material cost in building coal boiler
ZG is one top material cost in building coal boiler manufacturers in China, with long history and best technology to backup, also capable of design and fabricating this kind of boiler within the range of 1 to 320t/h, our products from gas fired boiler to biomass fired boiler, from firetube boiler to watertube boiler, from chain grate boiler to cfb boiler, from oil fired boiler to coal fired boiler. ZG Boiler is committed to manufacturing high quality and high efficiency boiler for both domestic and overseas consumers.
Five coal-fired material cost in building coal boiler gas boiler should pay attention to change the key to change the coal-fired boiler gas boiler should pay attention to the five key coal to gas project in the current renovation work, is more common in different regions, we continue to time nodes began to carry out, then, for the transformation of coal-fired boiler more standards-compliant, you need to note in particular the following five areas: (1) removal of auxiliary original coal-fired boiler, the boiler because if you want to fit in fuel, after the boiler auxiliary systems that should be a complete set. (2) the installation of blast doors. (3) of the boiler pressure test 1.5 times the working pressure. (4) in particular, to note that choosing the right matching burner, because the boiler during operation, the combustion machine is good or bad, is one of the important factors that affect the efficiency of the boiler. (5) In general, we should not try to change the pressure of the boiler body member portion, to make only a partial transformation of the furnace wall and the furnace arch. Of course, coal-fired boiler gas boiler change relatively strict, need to take into account the points will be more, just above these aspects must be considered in place of the step, which is to facilitate the follow-up work. In addition, the renovation work, if that time coal-fired boiler using some of the more than ten years or even longer, it is recommended to consider the purchase of a new gas boiler.
1, should guarantee the smooth flow of flue gas, have a good fullness and should avoid dead ends and dead.
2, the burner should be provided at the height position of the center of the furnace, and the combustion space and has sufficient length. Flame should not be flushed to the wall heating surface, so as to avoid incomplete combustion gases local overheating and damage to the wall.
3, since the combustion gas in the furnace backlash, high thermal strength, exposed to the bottom of the drum in the furnace should be adiabatic process.
4, various pipes, fire tube boiler furnace wall substantially refractory brick masonry, and shield plus insulation material. In the "coal to gas" should pay attention to the tightness of the furnace wall, minimizing the original door, door checks, etc., can assemble the refractory block, prevent cold air flames wounding or excessive leakage into the furnace , affecting boiler efficiency, to see the fire hole must remain closed also should see the fire hole, heat-resistant glass viewing by fire.
5, the furnace boiler and gas than coal-fired boilers, is generally greater, there is sufficient combustion space, increase the volume of gas, does not affect the transformation of combustion conditions. If the user requests output significantly improved boiler, the furnace can be increased radiation heating surface, to remove scale and soot while the inner surface of the outer heating of the original, so that without increasing the volume of the boiler case to improve the boiler output is not a problem. Thermodynamic calculations must do in the boiler, while the smoke but also good wind resistance calculation intensity calculation.
To speed up the transformation of coal-fired material cost in building coal boiler 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.
