1400kw biomass pellets automatic chain grate stoker heating oil boiler

  1400kw biomass pellets automatic chain grate stoker   heating oil boiler product description YLL series heating oil boiler is vertical assemble type liquid forced circulation boiler. It takes coals as fuel. With the compact heating surface (radiant heating surface and convection heating surface), the boilers adopt multilayer closely-arranged coils and ceiling coils so as to lay out enough heating area. The flue gas experiences many rounds of heat transfer in the “S-Form”, the heat efficiency is high.   Features: 1      Take multilayer closely aligned coils as heating area Heating area is the multilayer closely aligned round coils. Heating area is arranged sufficiently and absorbs the heat from the multi-passes flue gas. The coefficient of heat transfer is very high. 2      The ceiling coil The ceiling coil on the top of the radiant heating surface can protect the furnace top from being burned out. 3      Compact structure The boiler is in compact structure, which greatly saves the space of boiler room. 4      Waste heat boiler or air preheater The waste heat boiler (or air preheater) is mounted to recover the energy in the exhaust gas so as to improve the efficiency 5      Rational medium procedure The medium enters from the low position and flows out from the high position. In this way, the exhaust gas can be discharged out of the boiler smoothly. 6      Good exhaust gas outlet position The exhaust gas outlet sits right above the boiler, which can balance the heating surface and rationalize the structure. 7      Special furnace arch and furnace grate design 8      Convenient installation The installation is very convenient and flexible, just need to place the boiler on the foundation.
