merchant steam system boiler

1 ton gas steam merchant steam system boiler these "parameters" what's the point? Rated evaporation gas steam boiler 1 t 1 t is to provide 600,000 kcal of energy per hour, can produce about 10 tons of water at 60 deg.] C per unit time, can be used for 8000 square meters workshop or room heating, can be for the 120 or so people at the same bath, in industrial production and heating heating industry is widely used.

Flue gas fuel merchant steam system boiler design requirements fuel gas boiler flue design requirements: 1. The flue should be straight, air tightness, attachment and less and less resistance, more than 1% level to maintain the flue should rise laying layout, try to avoid Longitudinal arrangement. 2. Fuel gas-fired boiler house and chimney flue should be constructed of steel or reinforced concrete, the lowest point of the flue and chimney should be set to seal air-conditioners, water drains. The thickness of the metal sheet 3. The flue generally use 4 ~ 6mm, the flue design, should be sufficient arranged reinforcing ribs to ensure the strength and stiffness requirements. 4. The thermal expansion of the flue should be compensated, the compensation amount to be calculated and the correct selection. The steel flue insulation measures should be reliable and fixed. 6. The fuel gas boiler corresponds to a boiler should be 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. The flue should be arranged to set 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 longer 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.

Industrial gas condensing merchant steam system boiler works and the core technology of industrial gas condensing boiler, by definition, it is a condensing gas boiler. Currently, condensing gas boiler can be divided into commercial gas condensing boiler and condensing gas boiler industry. Products are also different from the horizontal condensing boiler and condensing boiler vertical. The most important is to realize the nature of condensing boilers condensing technology. The key industrial condensing gas boiler condensing boiler key point is to use the condensing technology, which is a relatively new type of energy-saving and environmental protection technology. In fact, the principle is not complicated, the simple conclusion is that to recover the heat energy of the flue gas through the flue gas condensation. In general, the traditional boiler thermal efficiency of only 85% or 91%. The exhaust gas boiler condenser temperature was lowered to 35-60 ℃, full recovery of latent heat and sensible heat in the flue gas water vapor. Maximum thermal efficiency of up to 108.9%. Industrial works condensing gas boiler works condensation gas boiler is the hot flue gas discharged from the combustion boiler (typically from about 140 deg.] C) recovering the energy, the temperature of the exhaust gas after recovering only about 60 ℃. Thus, the thermal efficiency is improved about 10%, about 10% gas savings. Meanwhile, in the process of energy recovery, it is also possible to reduce harmful emissions, reduce environmental pollution.

(DB44/765-2019)

Recently, Guangdong Province issued a "Boiler Air Pollutants Emission Standards" (DB44 / 765-2019) (hereinafter referred to as the "standard").

A "standard" in the context of the implementation province domain for coal, oil, 65 tons of steam per hour and the material forming steam boiler burning fuel gas and raw, hot water boilers of various capacities and organic heat carrier boiler; stoker of various capacities, stoker furnace.

Second, the implementation of the emission limits of air pollutants specified in Table 1 of the boiler since July 1, 2019, since 2020 July 1 implementation of air pollutant emission limits specified in Table 2.

Third, the new boiler since April 1, 2019 (the date of the present embodiment standard) executed from air pollutants emission limits specified in Table 2.

Fourth, not the implementation of clean energy transformation of 35 tons of steam per hour and higher coal-fired boiler from January 1, 2021, implementation of the provisions of air pollutants emission limits in Table 3 in particular.
