Gas-fired steam boilers and coal-fired steam boiler which is more energy-efficient? General business in the procurement of steam boilers were more often or consider production efficiency problem, we need to know what kind of fuel steam boilers more energy-efficient choice is clear, and that is the most common gas and coal-fired steam boiler steam boiler comparison which is more energy efficient? Following on from me give you an analysis. Clear answers to the same model or coal-fired steam boiler energy saving compared to steam boilers, we can roughly be calculated next-ton per hour boiler work at full capacity to 150-160Kg according to the market value of coal fuel, and gas to around 80m3 of gas. A further additional energy means 'gas' is higher than the calorific value of 'coal' fuel value, and then under the same conditions, producing one ton of steam, of course, fast burning gas. Also a ton of water to generate a tonne of steam, in theory, as much heat energy is required, the low single coal market price, it is cheaper than burning gas. But better to burn coal gas and environmental protection in environmental protection. If a large amount of production if the proposed biomass boiler, coal processing than such low investment, but also more environmentally friendly.
Pressure steam boiler shutdown fire you do not know the techniques and precautions steam boiler refers to water heated to a certain temperature parameters and the production of industrial steam boiler, the water in the steam drum is heated to become vapor, fire emits heat in the furnace, It is the principle of the steam boiler. Steam boiler belongs to special equipment, design, processing, manufacturing, installation and use of the boiler must be supervised by technical supervision departments, users only get to use the boiler permits to use steam boilers. Fire pressure steam boiler shutdown is interrupted by slowly burning until the load drops to zero until a planned shutdown. Specific steps are as follows: 1, to reduce boiler load, according to the length of time of shutdown, the seam thicker, the thickness is generally not more than 200 mm, suitable to accelerate the speed of the grate. 2, the distance to the thick seam slag is about 1 mm grate stop rotation of the drum is stopped, the operation of the induced draft fan, blowing off a small segment of the regulating plate stopper and dampers qs, relying on natural ventilation to maintain coal lean-burn, the sewage, boiler water level will rise to the maximum allowable level. If the fire burn coal gate, grate can be switched on again, the gas will move back some distance. 3, the recovery boiler needs to run, as long as the opening lead, a blower, to adjust the smoke, and the wind baffle plenum segment adjusting the opening degree of the shutter, the adjustment of combustion steam boiler seam thickness to be normal, start grate, to resume operation .
By the end of 2016, the State Council issued separately "" Thirteen Five "environmental protection plan" and "" Thirteen Five "energy-saving and environmental protection industry development plan", environmental planning and environmental protection industry to make guidance. During the two sessions this year, environmental protection is also a hot topic. Policy of continuous progress, and constantly increase investment in environmental protection efforts, more and more industries engaged in environmental construction. In the pharmaceutical industry, pharmaceutical equipment associated with its environmental protection has also been vigorously sought after by the market, the drug manufacturing must seize the favorable policies, increase research and development of energy-saving, environmental protection, pharmaceutical equipment.
In the pharmaceutical industry, industrial steam and pure steam is essential production conditions, mainly heating and apparatus for sterilizing products. The main steam from natural gas and other fuels to generate heat in the boiler, and the boiler consumes a lot of fuel per year. Currently, many enterprises will be condensed water vapor produced direct emissions, which not only pollutes the environment, but also lost a lot of heat and precious water resources. If we can be recycled, either generate economic benefits, can also protect the environment.
For a long time, boiler manufacturing industry has been committed to upgrading boiler welding technology to improve the level of boiler manufacturing technology, especially in recent years, domestic production of boiler equipment companies are active in technological innovation, and the introduction of new equipment, new technology to promote advanced welding to accommodate boiler capacity, and the parameter variations furnace, boiler meet the complex structure of the new materials and the welding member boiler.
Experts said boiler technology has made some progress, but the low efficiency of industry resources are distributed, disorderly market competition, product less competitive and other issues also plagued the entire boiler industry. Boiler welding technology, while progress has been made, but the level of automation of welding part of the product to be improved, welders welding quality is good or bad is still dependent on the technical level.
Market demand, the major boiler manufacturers are actively cooperate with professional welding equipment manufacturers to develop new welding equipment and welding technology. In recent years, China's major boiler plant are actively carry out technical transformation, the introduction of new technology and new equipment, and actively implement new advanced welding technology, adapt to changes in the parameters of boiler capacity and the furnace, boiler and boiler components to meet the complex manufacture of new materials requirements.
Insiders said that in terms of stabilizing the economy and achieve long-term sustainable development, energy saving and environmental protection industry is an important force. After the new GMP implementation on some equipment and production conditions put forward higher requirements, how to meet the production requirements of the premise, as far as possible to reduce energy consumption, which has become a headache problem of large pharmaceutical companies. Use energy boiler system is an effective way in the pharmaceutical industry to achieve energy saving, reduction of pollutant emissions fog.
Changing and blessing, natural gas fuel development and application of national energy saving policy of energy supply system will enter a period of rapid development, coal-fired industrial boilers will gradually withdraw from the center of town. Launched around the "coal to gas" and other policies is to verify this fact. In the context of social development, boiler manufacturing industry must adhere to market-oriented strategy to develop science and technology as a weapon boiler, under the guidance of relevant national policies, enterprise architecture and product structure adjustment, to obtain long-term survival and future development.
The main difference between the gas boiler and gas steam boiler What is the main difference between what gas boilers and gas steam boiler is? Nominally, a clear distinction between gas and steam boiler wherein the boiler fuel gas is different. The former use of natural gas, which uses coal. I think a lot of user concerns boiler is why they should cancel gas-fired boiler, because many people have purchased and used the gas boiler. If they switch to gas-fired boiler, it will be a huge expenditure. First, according to the current direction of development of the ecological environment of China, gas boilers will gradually be replaced by gas-fired boiler or other clean and green energy boilers, gradually withdraw from the stage of history. To say a big difference between the gas boiler and gas steam boilers, gas-fired boiler is mainly due to the elimination of environmental protection. From the fuel supply portion, only a gas boiler tube connected to the boiler; gas boiler needs coal field, coal (with or artificial), coal transportation, handling, storage and loading of coal boiler process. It will produce dust, causing serious pollution to the people's living environment. From the point of view of atmospheric emissions, natural gas is very small dust content, substantially negligible; high ash content of coal, the ash content of about 10-30%, the combustion smoke. If dust emission reduction facilities, emissions will increase; if more dust removal facilities, the corresponding costs will increase, this is not a long-term solution. In addition, the sulfur content of natural gas is very small, dust removal, desulfurization and denitrification can get gas boilers, gas boilers need only consider the denitrification problem. From the other point of view of waste disposal, natural gas substantially free of other contaminants, especially in city gas. In the case of coal, the coal field (especially small boilers mainly built in the open air) to produce coal slurry water during the rainy season, or sink into groundwater. When entering the surface water, the combustion ash conveyance of dust is generated. Of course, there are differences also in other ways. For small boilers, gas boilers are more energy efficient than gas boilers, equipment flow is simple, small footprint, low operating and maintenance costs, and so on. These are the main difference between the gas boiler and gas steam boilers, as well as the significance out of gas boiler. As can be seen, the use of gas-fired boiler is the trend of the whole society.[email protected]
