When the details of power plant boilers is used, it is necessary to pass the heat balance test. When considering the actual benefit of the boiler room, not only the thermal efficiency of the boiler, but also the energy consumed by the auxiliary equipment of the boiler should be taken into account. When the fuel is completely burned per unit mass or unit volume, the air demand calculated by chemical reaction is called theoretical air volume. In order to make the fuel burn in more contact with oxygen in the furnace, the actual air flow into the furnace is always larger than the theoretical air volume. Although the heat loss of incomplete combustion can be reduced by adding more air, the heat loss of exhaust smoke will increase, and the corrosion of sulfur oxide and the formation of nitrogen oxide will also be aggravated. Therefore, efforts should be made to improve combustion technology, Try to complete the combustion in the furnace with as little excess air as possible.
Yesterday we learned that the Guangdong Province to increase pollution control efforts by the provincial people's government approval, Guangdong Province Market Supervisory Authority, the ecological environment of Guangdong Province, Guangdong Province, recently issued jointly approved by local standards "details of power plant boilers air pollutant emission standards." Compared to the original standard, including contaminant particulate matter, sulfur dioxide, nitrogen oxides, etc. received strict emission limits help to further reduce the total emissions of air pollutants.
Provincial Department of environment-related offices responsible person, the current Guangdong Province "Boiler Air Pollutants Emission Standards" promulgated and implemented more than eight years, with advances in pollution control technology, emission control requirements of its apparent leniency. Meanwhile, Guangdong air pollution control task is arduous, urgent need to close strict standards, further reducing the total emissions of air pollutants.
Guangdong "boiler air emission standards" in the context of the implementation province domain for coal, the material forming the fuel oil, gas and raw fuel 65 tons of steam per hour and less steam boilers, hot water boilers of various capacities and Heat Transfer Material Heater; stoker various capacities, stoker furnace.
The new "boiler air pollutant emission standards" (DB44 / 765-2019) to adjust six major areas.
A clear the raw fuel material forming air pollutants emission limits fuel boiler;
Second, the received strict emission limits boiler air pollutants, increasing the emission limits coal boiler mercury and its compounds;
Third, the abolition of provisions different emission limits by functional area and boiler capacity;
Fourth, in particular an increase of atmospheric pollutant emission limit requirements;
Fifth, increase the fugitive emission control requirements;
Sixth, the excess air ratio conversion flue gas pollutants to the atmosphere of pollutants emission concentration of the reference oxygen content conversion, the oxygen content of the clear reference atmospheric pollutants fired boiler burning biomass.
The new standard in the province gamut execution, the execution time of the specific step-wise: new boiler effect since April 1 this year; the transformation of boilers give some time, depending on which region, from 1 July 2019 2020 or the date of July 1 implementation of the new standards.

Factors affecting the efficiency of a condensing details of power plant boilers, condensing boiler correct operation. Condensing boiler with a preset value the quality of work and the individual device operating parameters have a great relationship, when discrepancies operator to adjust the parameters of the amount of condensing boiler equipment presets and the environment, or the sequence of different operations confusion when may also lead to a condensing boiler use, the system Caton, leading to excessive condensation of water, low pressure or no change in temperature anomalies. Therefore, before using a condensing boiler and use it is best to have a professional guide and strictly follow the instructions. Second, the maintenance and repair of condensing boilers. Care and maintenance condensing boiler can directly determine the stability of the life of equipment and performance in a way, any time of the shutdown condensing boilers are extremely demanding, before stopping off after a period of time, a full periodic abnormal exclude dirt between the lines to clean up and, once the line is damaged or loose parts should be made in a timely manner in accordance with the instructions precautions to avoid large-scale accident late. Third, the condensing boiler equipment parameters and specific circumstances do not apply. Adaptability condensing boiler and to ensure that the environment is substantially ensure stability of the system must first determine the various parameters of the interface where the boiler system itself good in the purchase history of a long-condensing boilers, thermal energy value, pipe size, the space available areal extent, so as to determine the appropriate model parameters and condensing boilers combined with the original use of the energy system, so it can ensure an actual condensing boiler with the same use environment.
Practical Applications. Explosive deslagging of the boiler has even been performed online, with the unit turned down to low load. Check out these videos of actual power plant boiler deslagging operations: video 1, video 2, and video 3. Outside the boiler, explosives have been used to clean such power plant components as scrubbers, fly ash silos,Learn More
