Condensing steam how to increase boiler performance thermal efficiency condensing steam boiler analysis is the use of flue gas condensation heat recovery efficiency of latent heat is absorbed in the rear of the boiler flue gas and the sensible heat released by condensation of water vapor, to achieve the purpose of improving the thermal efficiency of the boiler. Boiler system, 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 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.

The development of industrial furnaces comprehensive remediation plan, establish management classification list. Carry iron and steel, building materials, thermal power and other key industries and fugitive emissions of coal-fired boilers investigation, the establishment of management accounting.
Good implementation of ultra-low emission coal-fired plants green electricity, coal-fired boiler out of grant funds to develop policy, research and comprehensive utilization of straw Jinshao, out of old cars, coal-fired boilers ultra-low emissions and energy efficient building renovation and other key tasks to support policy and actively for the central and provincial special funds for air pollution control.
First, 10 tons of gas how to increase boiler performance installation scheme 1, the installation needs to inform the local quality supervision department for; 2, boiler installation; 3, installation and connection of auxiliary equipment; 4, the connection between the boiler and the steam pipe;
Gas heating how to increase boiler performance operation and management system to resolve the gas heating boiler heating system will be relatively complex, requiring a strict management system to ensure safe heating boiler running smoothly in this process need to pay attention to the following points: 1. The quality of boiler water must to go through rigorous testing, sub-standard water to be softened to avoid scaling, corrosion and other boiler components after use, affecting the thermal efficiency and operational safety late boiler. 2. boiler and its auxiliary system is operating normally, if abnormal timely feedback process. 3. Ensure the indicators boiler water systems, safety accessories and other normal and flexible. 4. boiler operator rigorous specialized training and work and strict management system, be sure to do, patrol officers and operators keep alert, can not be insensitive. Inspection time designated times to be once per hour. Period of time to carry out maintenance and repair timely 5. boiler shutdown. To ensure that the boiler inside and outside the normal indicators, the device remains clean and orderly. 6. In addition, during each inspection of boiler operation, inspection, etc., must do text and data records to ensure that when the transfer of work to be a clear understanding of boiler operating conditions between the transfer of personnel. Of course, the normal norms of these will be far more complex, these are the general direction in which, in any case, to ensure safe operation, the safety of gas heating boiler, while maximizing operating results play a boiler, strict implementation of the operation and management system It is a necessary operation.
