china automatic gas or oil steam boiler

Gas-fired china automatic or oil steam boilers and pressure hot water boiler has what a difference, the most critical is that goods difference: pressure hot water boiler production part of the standard high-temperature water; the production of gas steam boiler is part of the standard steam. Second, the auxiliary little difference: like supporting pressure hot water boiler water circulating pump, does not need gas steam boiler; gas steam boiler water level gauge support, do not need pressure hot water boiler; gas cylinder steam boiler supporting points, pressure hot water boiler with tank; Third, the production boilers, boiler installation, a boiler, a steam boiler safety of the gas stringent requirements. Fourth, the key difference is the use of gas boilers steam production is saturated standard high pressure gas for power generation, tie-dye, medical and other fields, is due to the production of saturated steam, pressure equipment is therefore, a boiler and the boiler installation must meet Compliant pressure hot water boiler is the production of high temperature water, not a pressure equipment. How to gas steam boiler blowdown gas boilers | oil boiler | Environmental Equipment Co. steam boiler (1) open inside discharge water valve; (2) slow external open blowdown valve, and the discharge duct for warming; (3) back and forth on the exterior from the opening and closing of the blowdown valve, the buffer boiler dirt stains, so that the dirt is discharged as water stains; (4) the inner blowdown valve closed, the waste water stored between the two valves drained water; (5) external blowdown valve closed, to complete the discharge.

Battle to win the blue sky, is the major decisions and plans to make a big party in the nineteenth, and is for building a moderately prosperous society, to improve the quality of life of citizens and establish a beautiful China's development goals. To fully implement the nineteen spirit, promote the governance of air pollution intensity and improve the living quality of the environment, this year March 8, Zhengzhou Municipal Party Committee General Office, Zhengzhou Municipal People's Government Office issued the 2018 air pollution control program and the corresponding subsidy policy, the implementation of low-nitrogen gas boiler retrofit demonstration project, as follows:

Before the end of September 2018, the city's more than 20 tons of steam (with), and the urban areas more than 4 tons of steam (with) the completion of gas-fired low-nitrogen transformation project demonstration projects, nitrogen oxides emission concentration is not higher than 30 mg / cubic meter, City level financial awards complement carried out in accordance with the 40% investment in equipment;

Before the end of September 2018, the city's more than 4 tons of steam (with), and the urban areas more than 2 tons of steam (including) low nitrogen gas boiler reconstruction project completed demonstration projects, nitrogen oxides emission concentration is not higher than 30 mg / cubic meter, City level financial awards complement carried out according to 30% of equipment investment;

Before the end of April 2019, the city completed all gas-fired low-nitrogen transformation, nitrogen oxides emission concentration is not higher than 30 mg / cubic meter, the municipal finances awards complement of 15% investment in equipment.

Multi-fuel china automatic or oil steam boiler protection water protection Fuel steam boiler: boiler water level gauge plate supporting one to two, should always be compared with each other, findings indicate inconsistency shall be corrected immediately. Class water level should be flushed, to determine their true level. While the water level comes electrode rod can accurately capture level signal to an alarm or a pump control. A steam pressure protection, the pressure controller: selection of high sensitivity of the pressure controller, the pressure is high, or low levels of signal to the electrical switches, automatic control chain protection or other control lines. Using pressure controllers and electrical contacts, the vapor pressure can overpressure alarm; single adjustable pressure controller or dual fire burning fire the actual operating pressure. 2, the safety valve: safety valve is the last line of defense to protect the boiler, the boiler pressure exceeds the limit, according to the set pressure relief valve design with the school, the exhaust steam pressure relief, to ensure the normal operation of the boiler. Flame protection: imported burner having a flame protection device, combustion function is to detect, when the ignition failure or extinguish combustion middle, immediately off the burner into the oil (gas) solenoid valve, the blower continues to operate at this time, the furnace was purged of residual internal combustible gas, after 20 to 30 seconds purge, and various auxiliary blowers automatically cut off power, the boiler operation stops. Self-locking power failure protection: Under the emergency power supply is interrupted, the boiler shutdown immediately self-locking, if the current power is restored, the boiler will not start at any time, you must reset release self-locking, to re-start the ignition.

Power plant boiler working principle

Power station boilers are an indispensable device in thermal power plants. They generate high-temperature and high-pressure steam by burning various fuels (coal, oil, natural gas, biomass fuel, etc.). This steam is used to drive a steam turbine. Generator attached to the steam turbine generating electricity.
