Third, improve environmental benefits
Since the combustion of natural gas itself is adequate, and clean burning, non-polluting emissions is a more environmentally friendly energy sources. After coal combustion emissions from sulfur, more ash, environmental pollution more serious, which is incomparable with gas boiler. Gas boiler can bring greater environmental benefits to the enterprise.
The heat exchange surface of Fangkuai 1200 kw vertical coal fired boilers is reformed reasonably: 1. The horizontal boiler is removed from the furnace arch of the original furnace, and the coal bed is covered with insulation layer and refractory brick, which is transformed into the secondary radiation surface. Vertical boilers can build radiation reactors at the bottom of the furnace and install radiation arches on the upper part of the tank. 2, control the leakage air volume of furnace and flue. It is necessary to seal the boiler's observation hole, to seal the boiler's air duct and flue, especially when the air leakage rate of brick air duct and flue is large, after changing to burning gas, it is necessary to carry on the sealing treatment, preferably to change to the metal flue. When multiple boilers share a total flue, each boiler Breakers should be installed on the flue to prevent flue gas and residual gas from the purging process from flowing into the boiler furnace that has ceased to operate. Reasonable selection of burners for Fangkuai boilers: 1. Under rated gas supply pressure, the thermal load of the burners must meet the requirements of the boilers. Combustion is complete, excess air coefficient is low, combustion temperature is high, combustion noise is small, furnace flame fullness is good, flame radiation ability is strong. 2, the load regulation ratio meets the requirements of boiler operation, and the excess air coefficient can be adjusted. 3, can realize the boiler safety technical supervision regulations issued by the Ministry of Labor automatic control project.
First, in line with environmental standards, higher efficiency due to low gas other fuel gas 1200 kw vertical coal fired boilers ash, sulfur and nitrogen than coal, burning more fully, and thus the amount of dust in the dust rarely, can greatly mitigate environmental pollution, and better meet the environmental requirements of modern production, on the other hand due to better overall environmental performance of a gas boiler, prompting the convection bank erosion bear small, good heat transfer, heat radiation and strong, low exhaust gas temperature, thermal efficiency is significantly improved, better use of effects to enhance the overall durability of the good gas boiler, prompting the two complement each other to produce the effect.
To speed up the transformation of coal-fired 1200 kw vertical coal fired boilers project, the Tianjin Municipal Government were tender for coal-fired boiler products. In the bidding site, a number of boiler prosperity across the country have resorted to every means, come to bid on his own star product. Fang fast low nitrogen water tube boiler with its unique architecture and technology, will come to the fore in this bid, the successful bidder Tianjin Justice Drive surrounding district project.
