SHL20-2.50-M Shanghai coal-fired boiler brand ranking
ZOZEN boiler innovates new low nitrogen gas hot water boilers to further improve thermal efficiency and reduce emissions, leading the industry. The boiler can be divided into WNS series horizontal internal combustion wet-back gas-fired hot water boiler and SZS series double-pot vertical gas-fired heat boiler: water boiler, which can meet different heating needs, shl20-2.50-m Shanghai coal-fired boiler brand ranking.
Shl20-2.50-m. Brand ranking of coal-fired boilers in Shanghai. DHW series coal-fired hot water boilers adopt single horizontal reciprocating grate. At the same time, the air supply from the isobaric silo and the air distribution in the micro-zone also reduce the carbon content of the slag. In addition, the boiler body around and in the middle of the partition wall are all adopted membrane type water wall seal structure, the flag type convection heating surface is also adopted the same velocity design, reduce ash fly, further improve the heat transfer coefficient, to ensure the longgang district people warm winter to provide adequate heat source protection.

The circulation of materials in the circulating fluidized bed boiler is started and maintained by the kinetic energy provided by the blower (including the primary and secondary fans, the return fans) and the induced fans. The air fan out from a powder into a _ 2 into the chamber: the first way: after – wind air preheater Cheng heated hot air into the furnace at the bottom of the water cooling room, decorate through the cloth wind plate, hoods on bed material fluidization, and form up through the chamber of a stove or furnace gas solid two phase flow if the bed oil ignition way road also sets a duct igniter. The second way: after the air = preheater heating hot air to the upper part of the coal feeder before the furnace as a sealing wind.
The process control network of the system adopts a dual high-speed channel and a redundant SCnet II, which directly connects the control unit, operation station, engineer station and server of the system. It is a channel for the transmission of real-time process control information, with high real-time performance and reliability. The redundancy design of SCnet I ensures the high-speed and reliable transmission of all field control layer information, such as system process parameters, operation instructions, configuration information diagnosis information, alarm information, etc., and realizes the operator’s monitoring and control of the process.
