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 "boiler steam electric heating pressure vessel 2018 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.
2 t 2 t electric steam boiler steam electric heating pressure vessel 2018 price electric boiler steam boiler price of pharmaceutical laboratories for pharmaceutical boiler of the boiler is concerned, based on reserves of clean energy in terms of different regions, not only gas-fired boilers, biomass boilers, electric use of the boiler is relatively frequent, fast square below Zhengzhou small series to a simple analysis of the price of 2 tons electric steam boilers. Price simple two tons electric steam boilers and boiler auxiliary equipment is in terms of configuration comprehensive consideration two aspects, as freight, installation costs, etc., are based on the actual consideration of the actual situation. For Zhengzhou parties were quick to simple accounting, the price of one ton of basic electric steam boiler at around 90,000 yuan, the price of the specific needs of specific accounting based on the actual situation, then, the price of two tons of basic electric steam boilers in 18 ten thousand yuan or so. Of course, in the process of purchase, the basis for subsidies in different parts of the country will make the appropriate subsidies in different ways, so the actual cost of the boiler may not be so high. Therefore, the process of performing pharmaceutical boiler selected, if the site is suitable to run the boiler using electricity to drive the boiler, so in the meantime, the best combination of factors are taken into account, make a reasonable judgment. Of course, here small also like to remind everyone that during electric power steam boiler selection, in addition to considering the price factor than the boiler, the boiler overall cost, such as thermal efficiency, quality also need to be taken into account, after all, fit is better.
What is different from the hot water boiler steam electric heating pressure vessel 2018 and steam boiler there? There are many companies will operate on steam boilers do this relatively high cost of care. After the scene since the late boiler equipment, equipment up and running is a big sum of costs. About enterprise, if choose for their own fuel boilers, boiler fuel efficiency will make use of further progress. Therefore, we demand that the cost of running on several different fuel steam boilers budget to know. Gas: Advantages: clean energy, high thermal efficiency, low cost. Disadvantages: gas adapter constrained condition. Produce one ton of steam costs about 240 yuan (gas prices by 3 yuan / square meter accounting). Fuel: Advantages: no pollution, high efficiency, no fuel constraints. Disadvantages: higher operating costs. About 594 yuan one ton of steam production costs (fuel prices accounted for 9.0 yuan / kg). Electric heating: advantages: no pollution and no fuel constraints. Disadvantages: is a secondary energy, high operating costs, the cost of producing one ton of steam is about 700 yuan (price 1 yuan / degree). Coal: Characteristics: low operating costs. Disadvantages: severe pollution in some areas, the use of restraints, cost of production of one ton of steam is about 150 yuan (coal prices by 1,000 yuan / ton accounting). Heat boiler is an important means to transfer heat to the appropriate fuel equipment, it is now being widely used in industrial production and heating and so on. Popular in the size of the boiler is a steam boiler and hot water boiler both types, many people who only know the boiler heating equipment, but can not tell in detail parting boiler. Today we gave Shandong steam boiler explain what the differences steam boilers and hot water boilers, after all, what! On the surface, we can understand heating hot water boilers and steam boiler heating method chosen is not the same, but the distance between the hot water boiler and steam boiler Moreover, detailed in what areas? The different output media we literally can be seen, the medium is hot water output from the boiler, medium boiler steam output of the steam. First, the user can according to their demand for the output media, choose the appropriate boiler. Different steam boiler space occupied by a high pressure vessel, through steam forming water is heated after the completion of the vapor compression heating, and the area of the pressure vessel by the use of less water boiler is an unpressurized vessel by virtue of heat temperature of the water to complete the heating, hot water boilers professional usually occupied by a larger location, but better able to complete the non-selection of the pressure vessel safety are better able to ensure the safety of those who use. Because the size of different heating and heat storage capacity of water vapor from a large, high-volume hot water boiler and thus be able to choose long-distance transport of heat pump delivery lost less able to complete large-scale transport of hot water requirements. The steam boiler because the steam freezes faster, so in the long-distance transport can lead to sudden drop in water temperature, so the size of two kinds of heat supply boiler equipment can withstand different. Heating steam boiler at different speeds when using the heat generated as the water transpiration and thus burn calories in order to ensure the needs of large steam generation, and thus the temperature rise faster fever faster speed; hot water boiler heated water to ensure that the temperature of the water in the use of Yung heat better, thus better able to maintain the heating heat.
