new industrial straw pellet steam boiler price
Compared with ordinary gas boiler, condensing gas boiler can improve the thermal efficiency of 15-25%, one year, input costs for business can save a small fortune in fuel. But we can not ignore, in order for correct operation condensing gas boiler to play its true strength.
First, it can improve the efficiency of electric heat boiler exchange and reduce power consumption. Experimental contrast, had run under the same conditions Taipower two boilers, electric boilers cleaned after maintenance than without cleaning and maintenance of electric heating boiler is significantly faster rate around 25%, which means that the electric boiler can be cleaned after the original basis 25% savings on power resources. Second, extend the life of electric boiler. By cleaning the inside cleaning member can effectively reduce the load of the main pump, heat exchanger, so that more smooth operation of the boiler, prolonging its life. If every one to two years time cleaning the boiler service life and maintenance, extend equipment 3--5 years.
It may also be that the expansion tank is not consistent with the constant pressure of the boiler. The height is less than 15 meters, but the constant pressure of the boiler is 2.5 kg / cm ~ 2. In order to maintain the 2.5kg/cm2 working pressure index, the boiler workers often carry on the replenishment water, which spills into the trench unambiguously, that is to say, the water is consumed as well as the coal is consumed. Shut down the furnace and do not maintain it. After the heating period, the boiler was shut down, temporary workers were dismissed, some boilers were full of softened water, some boilers were exposed to the atmosphere, lack of necessary maintenance.
Recently, the letters and the ecological environment unit, the letter of "boiler air pollutant emission standards" in the "gas boiler exhaust pipe predetermined height of not less than 8 meters, within 200 meters from the building around the radius of the new boiler room chimney when was the tallest building in which the chimney should be higher than 3 meters "requirement questions.
First, the new urban gas boiler chimney should be performed outside the specified height is 3 meters above the surrounding buildings (there are many communities within 200 meters around the building height higher)?
Second, on the 20t / h steam boiler and above, and more than 14MW hot water boiler to be installed pollution-line monitoring equipment, this means that a single 14MW boiler or boiler means the total audience of 14MW?
Third, for example, I have more than 2MW heating station natural gas hot water boiler 7 units, exhaust gas through the two exhaust pipe emissions, the need to install pollution monitoring equipment?
A "boiler air pollutant emission standards" (GB13271-2014) states that "fuel, gas boiler stack height of not less than 8 m, particularly boiler stack height is determined by the EIA document approved. Chimney around the new boiler room when there is a building within a radius of 200 meters, the tallest building in which the chimney should be higher than 3 meters. when there is a building within 200 meters around the new boiler house chimney radius, "according to the provisions in the new urban area gas boiler should be implemented", the chimney should be higher than the provisions of the tallest buildings in more than 3 meters, "the.
Two, 20t / h steam boiler and above, 14MW and more hot water boiler must be installed in the line monitoring apparatus contaminants "14MW and more hot water boiler" means a single boiler.
Third, on the "exhaust gas through the two exhaust pipe emissions, the need to install pollution monitoring equipment" problem, according to "People's Republic of China Air Pollution Prevention Law" Article 24 "key sewage units should be installed, using air pollutant emissions automatic monitoring equipment, and environmental protection departments to monitor network devices, monitoring equipment to ensure the normal operation of public and emissions information in accordance with law. "provisions, as well as the" State Council on the issuance of three-year action plan to win the blue sky to defend the notice "(Guo Fa [2018 ] No. 22) "outfall height of over 45 meters of elevated source, as well as petrochemicals, chemicals, packaging, printing, painting and other VOCs emissions from industrial sources focus, the focus of sewage into the Directory of key areas should be basically completed by the end of 2019 to install flue gas automatic monitoring facilities, the country should be basically completed by the end of 2020 the automatic installation of flue gas monitoring facilities. "requirements, if the exhaust pipe where the company was listed as key units of sewage, flue gas monitoring facilities should be installed automatically, otherwise, no installation.
