3, coal combustion brand fire tube pakistan boiler technology

This technique is performed by coal-fired boilers, pulverized coal amount to be injected into the furnace in place, so that the combustion grate base layer, an appropriate amount of the suspension increases combustion energy can be obtained a certain rate. As for boiler fuel, gas type, you can replace the old with the new energy-saving burner, behind the burner to be transformed.

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 "brand fire tube pakistan boiler 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.

In the two oil crises of the 1970s, natural gas was used as a fuel for brand fire tube pakistan boilers.

By the early 1990s, fuel-fired industrial boilers with a certain degree of technological development had a high market share in the boiler market.

Increase productivity brand fire tube pakistan boiler system must first be optimized for verification, including the entire steam system for a complete analysis, and focus on some of the energy waste places. Via check can often find opportunities to save energy, increase productivity, and environmental protection have a positive contribution of. Check includes a steam generation, distribution, use and condensate recovery. The main steam waste requiring special attention place: exhaust gas boiler: boiler efficiency emissions system the most important indicators, the loss of energy is the most important place. Combustion air: general air enters the combustion furnace of the genus room temperature, require a lot of heating energy, i.e., the most commonly used power saving mode using a high temperature exhaust gas to preheat the combustion air of boiler, boiler efficiency can be significantly improved. The fuel / air ratio: Proper oil / gas mixture can only complete combustion, if the lack of air, combustion is incomplete, not only smoky pollution, environmental protests caused nearby residents, and easy carbonized grease gun and boiler heating tubes affect performance. If excess air is formed wasted energy, reducing boiler efficiency. Via the oxygen content of the tail gas can appropriately adjust the oil / gas ratio. Oil-fired boiler exhaust gas which content 3%, i.e., the excess air of about 15%, as the standard combustion control.
