heating steam boiler 0 7 mpa 120 kg
Flue gas fuel boiler design requirements 1) to be straight flue, air tightness, attachment and less resistance is small, the level of 1% or more to maintain the flue rise should be disposed laying down slope disposed avoided. 2) the fuel gas flue and the chimney of the boiler should be of steel or reinforced concrete construction, the lowest point of the flue and the chimney should be water-seal disposed condensate drains. 3) thickness of the metal plate is generally used flue 4 ~ 6mm, the flue design, should be sufficient arranged reinforcing ribs to ensure the strength and stiffness requirements. 4) thermal expansion of the flue should be compensated, the compensation amount to be calculated and the correct selection. 5) steel flue and reliable insulation measures should be fixed. 6) a fuel gas boiler should correspond to a chimney boiler, when the boiler by the conditions required to share a chimney flue or several, each boiler should be ventilated suction force balance. 7) arranged in a flue provided when necessary thermal and environmental measuring point measuring point in place. Single rated evaporation amount is equal to 20t / h or single thermal rating of greater than or equal 14MW oil-fired boiler, a fixed continuous monitoring smoke flue gas must be installed. S02 emission concentration of the instrument. 8) Where the flue gas is easy to assemble, and when more than one boiler or a total share a chimney flue shall be fitted with explosion-proof door on the flue after each fuel gas-fired boiler, the location of the vent should be conducive to relief, should be provided without jeopardizing personnel safety and proper position before turning, when explosive gas may endanger the safety of the operator, should be installed on the guide tube explosion relief means. 9) For some of the longer flue boiler room, they should be accounted for resistance, select the corresponding drum, induced draft fan (ID fan when there), in order to ensure the smooth flow of exhaust. 10) should be considered appropriate chimney anti-corrosion measures, chimney flue gas outlet temperature is preferably above the dew point of the flue gas temperature of 15 deg.] C; when the exhaust gas temperature is lower than the dew point temperature of flue gas, the flue gas should take effective measures to prevent the intrusion.
Therefore, if the use of gas-fired boilers in these demanding city, if your gas boiler emissions has not reached 30mg / m³ or less, then your gas boiler to meet environmental protection requirements, and may face the risk can not be used!
Qinhuangdao City Funing District Branch of Ecological Environment Agency organized the key enterprises responsible person within the jurisdiction of the boiler demolition, renovation work will hold a special schedule. The meeting stressed the need to vigorously promote coal-fired, gas-fired boiler demolition, renovation work progress, continued to improve ambient air quality.
At the meeting, staff of the Office of atmospheric area of the current coal-fired, gas-fired boiler demolition, renovation progress has been informed. Up to now, boiler demolition and reconstruction of the region involved all disabled.
First, Funing District compressed air quality improvement increasingly smaller space, air pollution prevention and control situation is very serious, involving various enterprises must attach great importance to effectively assume responsibility for environmental protection.
Second, the coal-fired boiler in accordance with the "water power, chimney down, shifting the body" standard transformation and low nitrogen oxides emissions analyzer mounted nitrogen gas boiler work requirements, make sure the end of this completed, the embodiment late cut-off regulation.
Third, the Bureau of atmospheric sciences, environmental law enforcement unit to further strengthen law enforcement and inspection and supervision, the monitoring center to provide scientific data monitoring, to crack down on environmental violations, it is important to ensure that coal-fired, gas-fired boiler demolition, renovation work is completed on time.
Boiler installation is very important, because the purchase of boilers is not a whole, the seller will carry a lot of boiler parts to the home and then professional personnel responsible for the installation of the boiler. If the installation work is not done properly, there will be a lot of problems when used later, so small as a screw to a boiler in the installation needs to be very important.
