5, steel flue and reliable insulation measures should be fixed.
6, a fuel gas boiler room boiler should correspond to a chimney, when required by the conditions a boiler flue or chimney common to several units, each boiler should be ventilated suction force balance.
7, when the flue arrangement provided the 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 must be installed in the flue gas dust, SO2 emission concentration instrument.
8, in the flue gas gathering place easily and when many boilers a share or a total 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, It should be provided without jeopardizing personnel safety and proper position before turning, when explosive gas may endanger the safety of the operator that should be installed on the guide tube explosion relief means.
9, for some long flue boiler room, they should be accounted for resistance, select the appropriate blower, Fan (when there is draft fan), to ensure the smooth flow of exhaust.
10, the chimney should be considered appropriate 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.
Recently, the Tianjin Beichen District issued a "Tianjin Beichen District in 2019 to win the Battle of Blue Sky battle plan" (hereinafter referred to as "Plan"). "Plan" put forward: to strictly control new coal projects, the implementation of coal consumption reduction project alternative, prohibit self-supporting construction of coal-fired power plants. Complete the transformation of low nitrogen gas-fired boiler more than four before the end of September 2019.
Details are as follows.
1, reducing the total coal consumption in 2019, the region's total coal consumption and coal in primary energy requirements meet the relevant indicators. Strict control of new coal projects, the implementation of coal consumption reduction project alternative, prohibit self-supporting construction of coal-fired power plants.
2, ongoing heating, agricultural, industrial and commercial management of coal-fired boilers, coal-fired boilers to burn consolidate shut down rectification results to ensure that no rebound. Carry out special rectification coal, coal supervision prominence to the implementation of high-quality coal supply and security, supervision and management of coal enterprises to establish a purchase and sale accounting, prohibit the sale of low-quality coal does not meet the requirements of state and city, by increasing the sampling frequency, strengthen information disclosure, strict qualification management, according to the law firm did not check other means, to crack down on low-quality coal to maintain circulation, sale and use of high-pressure situation. Ongoing heating season heating companies burning coal quality inspection. Strictly implement the relevant requirements of the city, set up to ensure that the region is no longer operating coal storage space, strengthen supervision.
3, to promote the safe and orderly clean warm winter residents. The completion of the outer ring 23 000 residents in rural areas "coal to electricity," the task before the end of October 2019, the region's urban and rural residents to achieve bulk coal for heating, "cleared."
4, before the end of September 2019 to complete the transformation of more than four low-nitrogen gas boiler. The full implementation of leak detection and repair (LDAR) system. Ensure the region involving volatile organic compounds emissions from industrial enterprises and supporting environmental protection facilities full coverage, stable and meet the relevant emission standards.
First, we must ensure that the electrical environment boilers should be in a dry, no moisture environment, if too much moisture environments easily lead to electric boilers appear even electrical phenomena occur, causing an electrical hazard.
