Tai Chi, Jiaozuo City, Jiaozuo City Sports Center is one of important sports infrastructure, a total area of 11.73 hectares, held several international events. With strict management in Henan Province for air emissions of pollutants, Jiaozuo City, also launched the governance of coal-fired boilers, thermal power and other equipment. Jiaozuo Sports Center actively cooperate with municipal workers, took the lead from coal to gas activities, the serious pollution of the original extent of coal-fired boilers to replace gas boilers. Gas boiler cleaning binding understanding of the market, to achieve cooperation with the finalization fast boiler by providing a fast side 2.8MW integrally condensing gas hot water boiler (WNS2.8-1.0 / 95/70-YQ), it is used to Sports Center provides heating and hot water.
What is the role and 150 pressure steam boiler economizer and what are the conditions? For boilers, the problem will be solved in the following, which specifically is: Energy Saver on the boiler, can play what role? Soil heating, radiators and boilers should be how to determine the height? And boiler and steam conditions What? Now that the problem has been brought up, and that the following immediately to give a specific answer to it and I hope that we have a complete understanding, in order to have a correct understanding. 1. The role of the boiler economizer in the boiler, economizer can play the role of the heat is recovered in the exhaust gas temperature to be utilized to increase the temperature of boiler feed water, the temperature of the blast, or directly to produce steam heating and so on. In this case, to avoid waste, at the same time, improve the efficiency of boilers, energy-saving goal. 2. soil heating, radiators and a boiler to determine the height of the case, for soil heating is concerned, first of all, is required to have pressure, so, to be achieved by the height difference between the backwater, namely, between boiler feed water and return pipe, the greater the distance, the greater the pressure difference. So, in general, back to the radiator outlet is higher than the boiler outlet back of 200-300mm. And, from the end of the radiator to the boiler, it is to have a two thousandths to three thousandths of distance downhill.
Introduction condensing boiler: condensing boiler efficiency is the use of flue gas condensation heat recovery boiler to absorb latent heat from exhaust tail and the sensible heat released by condensation of water vapor, to achieve the purpose of improving the thermal efficiency of the boiler. Thermal efficiency of the condensing boiler Analysis: conventional boiler, the exhaust gas temperature is generally 160 ~ 250 ℃, water vapor in the flue gas is still in a superheated state, it can not be condensed into liquid water and release latent heat of vaporization. As we all know, the thermal efficiency of the boiler low calorific value fuel is calculated without considering the heat loss of latent heat of vaporization of fuel in the high heating value. Thus the thermal efficiency of the conventional boiler generally only 87% to 91%. Waste heat recovery boiler is condensed, to which the exhaust gas temperature is reduced to 50 ~ 70 ℃, full recovery of the latent heat of condensation and sensible heat in the flue gas water vapor. Flue gas-fired condensing heat recovery 150 pressure steam boiler flue gas volume components typically produce 15% to 19%, the water vapor content of the oil-fired boiler flue gas is 10% to 12%, much higher than in coal-fired boiler water vapor content below 6%. Currently the thermal efficiency of the boiler are low calorific value calculation, although nominally higher thermal efficiency, but because of high natural gas, low calorific value difference of about 10%, the actual energy efficiency to be increased. To take full advantage of energy, reduce exhaust gas temperature, flue gas heat recovery physical, when the wall surface of the heat exchanger flue gas temperature below the dew point temperature, water vapor in the flue gas will be condensed, releases latent heat, low and high 10% calorific value difference can be effectively utilized.
1, due to the decrease of the atmospheric pressure, the fuel combustion speed slower burn time becomes longer, increasing the dissociation rate of the carbon dioxide, chemical incomplete combustion heat loss is increased. Solution to this problem is to appropriately increase the furnace volume, increased fuel residence time in the furnace.
2, no influence of the atmospheric pressure drop pairs exiled heat transfer coefficient of the heating surface, but decreases of Flame cause radiation heat transfer coefficient is reduced, so that the overall heat transfer coefficient is reduced. While reducing the radiation heat transfer coefficient caused by furnace exit gas temperature rise increases the convective heat transfer temperature difference, but to ensure that the exhaust gas temperature rises to a certain extent without excessive levels of convection heating surface area of the boiler should be appropriate increase.
3, low-altitude wind pressure effect on the smoke characteristics of a large gas-fired boilers, gas boilers running in the plateau region, the burner selection must be a revision in its air volume and pressure, ensure that the output power and boiler burner output.[email protected]

A boiler is an appliance designed to heat water and produce energy. The heat is applied to water in an enclosed container before being distributed throughout the system. The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and pounds per square inch gauge that the boiler produces.Free Chat
