Gas hot water 1t seller industrial boiler moldavia water circulation protection: gas hot water boiler water circulation proper protection measures, can effectively prevent the water circulation pump suddenly stopped, furnace water vapor and other adverse water hammer phenomenon. Fast boiler based on years of industry experience, summed up the protection for your gas hot water boiler water circulation, for your reference. 1, between the circulating pump inlet and outlet pipe, the check valve of the bypass pipe, the pipe diameter should be similar to the parent, and the bypass pipe cross-sectional area not smaller than 1/2 of the cross sectional area of the mother tube; check valve flow direction should be consistent with the direction of flow of the pump. 2, the weight of Formula inching valve provided on the inlet pipe section of the circulating pump, drain pipes which overpressure can open the access to the tank or drain.
Recently, the letters and the ecological environment unit, the letter of "1t seller industrial boiler moldavia 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.
Boiler furnace excess air control how to adjust? Boiler furnace combustion furnace excess air affects, therefore, how to effectively control the excess air ratio, is one of the prerequisites to protect the 1t seller industrial boiler moldavia reasonable run. Today to excess higher degree of automation of the gas boiler furnace air as an example to explain:
1, the hot 1t seller industrial boiler moldavia explosion accident prevention
