The reason the gas boiler burner increased noise analysis when making use of the gas boiler and found this small fire normal, but this time turn the fire, extinguished or flashing instability. First speaking, that is because of this fire damper of the air volume setting is too large; i.e. after an oil fire because the micro-switch valve (damper outermost that group) inappropriate setting (set lower than the fire damper of the air flow larger) burner gas noise increases, mostly because the oil shut-off valve which is closed or lack of oil into the oil filter clogging; or, this is because of low temperature into the oil, the viscosity is too high or the pump into the oil temperature is too high; oil pump failure; fan motor bearing damage; there is because the fan impeller dirty equipment resulting in large noise. The above-described failure when using gas boiler, but also because the viscosity is too high oleaginous easy to be atomized (heavy oil); cyclones and because improper disc and the nozzle pitch; Note that because the fire is worn or dirty nipple; also because this preparatory tank the heating temperature is too high, causing the oil pump oil feed steam does not conform; or because the fuel inside the boiler resulting aqueous oil. When the above-described fault gas boiler used to perform this process, the test should be done gradually decreases; after heating temperature should be; adjusting the distance (between 0 ~ 10mm); clean or replace; is set to about 50 deg.] C to about; or drain oil change.
Pressure boiler furnace designed with the characteristics of the fuel pressure boiler furnace designed with the two main parts of the boiler body is characteristic of the furnace and the fuel pressure drum. Furnace, also called a combustion chamber, a fuel combustion space. The solid fuel on the grate furnace called stratified combustion furnace, also called fire bed furnace, and a liquid, gaseous or solid powdered fuel is injected into the combustion chamber in a combustion furnace, combustion chamber furnace referred to, also known as for the furnace fire chamber, a liquid, a gas or a pulverized solid fuel injected into the combustion chamber of the furnace, also known as combustion furnace; coal particles and air lift to a boiling state combustion furnace for combustion of low-grade fuel is called boiling furnace, also known as fluidized bed furnace; high-speed rotation of the coal particles by a gas flow and strongly cylindrical combustion furnace known as a cyclone furnace. Atmospheric overall configuration of a boiler furnace body includes two parts and auxiliary equipment. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Furnace design needs to fully consider the characteristics of the fuel used. Each boiler combustion of the original fuel should as much as possible. Different characteristics of fuel economy will reduce boiler operation and reliability. It is a natural circulation boiler drum and multiple forced circulation boiler, economizer receiving water circulation circuit connected to the saturated steam supplied to the superheater of the cylindrical container. Boiler drum is made of high quality steel plate, it is one of the heaviest components of the boiler.
Gas-fired horizontal fire tube fired 1 ton steam boiler is an advantage on the device using an environmentally friendly energy-saving: With the designers re-design of mechanical innovation, simple and easy to operate equipment, gas steam boiler is not only relatively simple, and better ensure the safe operation of ; saving advantages: high-temperature low-pressure gas steam boiler with a characteristic greatly reduces the stress levels of heating equipment, less direct advantage is the reduction in equipment investment. Electric heating boiler and the boiler is mainly composed of electric control box and control system. Its characteristics are environmentally friendly, clean, no pollution, no noise, automatic, with limited energy and reduce prices significantly, as a new boiler electric heating boiler equipment increasingly being recognized. Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. It was also said that the proportion of contact with air, just the right amount of fuel and the amount of combustion air composition in order to achieve combustion efficiency, but also reduce gas emissions and achieve energy-saving dual, very convenient. Gas steam boiler may be configured according to the actual amount of steam required, thus reducing waste of energy. The higher the degree of matching the actual demand and supply theory, better energy-saving effect. Continuous sewage heat can be utilized by a heat exchanger, thereby increasing the water temperature deoxygenated water. Gas-fired steam boilers and other machinery and equipment, more in line with current environmental requirements, so it has been widely used.
Comprehensive reduce coal consumption, a few days ago, Baoding, Hebei Province issued a "blue sky Baoding win the Battle of three-year action plan" (hereinafter referred to as the "Program"), "plan" put forward specific solutions.
First, the heating pollution control
1, to reduce total coal consumption
Adopt an integrated coal reduction measures to reduce coal consumption. Reduction of new coal project alternatives. Complete bulk coal clean alternative area designated as a "ban on coal zone", in addition to electricity, central heating and raw coal coal-fired outside the "clear." Promote the use of clean coal, non-coal for electricity cuts, increase the proportion of electricity from coal. Enhance the proportion of clean energy, and actively develop renewable energy. Industrial Waste efficient alternatives such as coal and waste heat supply heat. Multi-channel expansion of natural gas supply, accelerate the construction of natural gas production, supply and storage sales system, develop non-fossil clean energy, give priority to renewable energy generation Internet, and actively carry out the heat, wind, solar and biomass energy use pilot projects. Encourage the development of biomass thermoelectric County have the resources to conditions of heat and power, biomass briquette boilers and scale natural gas chemical and biological substances. By taking measures to reduce coal comprehensive, complete province to decide Yajian coal consumption targets.
2, accelerate rural clean heating
To proceed from reality, should the electric power, gas should the gas, the coal should be coal, it should be hot is hot, the raised ring Beijing, the main city of Central City and other plain areas, rational distribution of science, science and progress targets set number of transformation to ensure the safety of the masses warm winter.
① heating diversified towns, villages conditional alternate embodiment of central heating.
② the completion of basic insurance North "ban on coal zone" and change to gas, electric construction of the main city, the main city ring accelerate dispersion of coal-fired and alternative Baonan key counties, and strive to three years to a total ban on the use of decentralized heating fuel Plains coal. "Substitution of gas for coal" adhere to the "gas will change" to ensure safe construction, safe use, security management, gas boiler energy efficiency of not less than level 2. The development of gas "pressure uninsured people" program, detailed list of contingency plans.
③ local conditions and actively promote photovoltaic solar, wind, biomass, geothermal heating mode, the implementation of solar heating pilot demonstration projects.
④ can not be implemented in rural mountainous areas clean heating transformation, and actively promote clean coal, and improve supply security system, the implementation of clean coal underpinning policy.
⑤ support agricultural production priority use of renewable energy, encourage the use of gas-generation coal, electricity generation of clean coal and other fuels such as coal generations, the phasing out of agricultural production in the plains with scattered coal-fired. 2019 basically completed the bulk of agricultural production of coal governance.
3, accelerate urban central heating
Promoting cogeneration heating energy structure, large-scale coal-fired boilers, geothermal energy, industrial waste heat as the main heat source, natural gas, electrical energy, biomass and other as complementary. Making full use of industrial waste heat, the conditions of the county to implement a city of a centralized heat source, synchronized planning and construction of central heating pipe network, and promote town extends to the surrounding heat source. Develop distributed heating gas boilers, electric boilers and other heat storage. Scientific and rational use of geothermal heating, into a film support regional development and utilization of geothermal heat pumps and the construction of gas distributed power station. Urban central heating can not cover all the villages in the implementation of clean energy alternatives.
4, strengthen the clean energy supply security
Establish a sound working mechanism of gas, emergency power supply security, oil and gas pipeline protection, on the basis of 2017 filled the gap on natural gas, natural gas plan focus on incremental substitution of gas for coal project in 2018, the 2018-2019 heating season to ensure that dual-generation project gas, electricity supply effectively improve the city's energy level security operation. Strengthen protection for air supply and power supply capacity, speed up the layout of the building and the city and county levels peaking gas storage facilities supply business, accelerate the improvement of the power grid and gas pipeline construction.
5, strengthen the bulk coal market and poor quality coal for control
According to sector regulation, local management, levels of responsibility and "who approved, who control", "who is in charge, who is the principle of supervision", strict bulk coal production, processing, storage, sale and use of corporate governance. Strengthen departmental interaction of law enforcement, strengthening the floor management to crack down on sales (including online sales) and use low-quality coal for violations. Strict control of industrial and civil coal quality, strict implementation of "coal quality coal for civilian goods" (GB34169-2017) standard, the quality of coal supplied to customers production and processing enterprises must meet the "industrial and domestic fuel coal" Hebei (DB13 / 2081-2014) local standards.
6, out of the transformation of coal-fired boilers to strengthen and deepen governance
Demolition firm covering central heating boilers scattered coal-fired in the area. The completion of the city 35 steam tons / hour and coal-fired boiler, stove and stove operating a small coal stove replace the task of transformation. Before the end of 2019, more than 35 tons of steam / h coal-fired boiler basically completed colored plume governance reform and ultra-low emissions, coal-fired boiler to retain the overall emission limits and achieve energy efficiency standards. Promote clean coal-fired boilers. A ban on new 35 steam tons / hour and coal-fired boilers. The main city and counties (cities, districts) ban on new built-up area 35 steam tons / hour and below a biomass boiler, more than 35 tons of steam / hour biomass boiler to achieve ultra-low emissions standards. Out central heating pipe network coverage and bulk coal fired boilers in the range, it does not have the area in cogeneration district heating conditions, and the like may principle of volume replacement, construction of large-capacity coal-fired central heating boilers alternative. Start the implementation of the transformation of low-nitrogen combustion gas boiler.
7, improve energy efficiency
