YLW series coal fired thermic fluid heater

YLW series coal fired thermic fluid heater   YLW series coal fired thermic fluid heater are the horizontal type compositional liquid forced circulation boilers. The furnace radiant heating surface locates in the front of furnace body and consists of monolayer closely-arranged (the inner sparse-arranged coils and outer closely-arranged coils) coils. The convection heating surface locates at the back of furnace body and consists of snakelike coils. The boiler comprises the upper body and the below combustor (chain grate stoker) and can be assembled on construction site; and behind the heater is the waste heat boiler ( air pre-heater). The fuel burns sufficiently and forms the high temperature flue gas, the energy of which is mostly absorbed by the radiant heating surface; and then the gas enters into the convection heating surface to exchange heat and moves out of the boiler; and then it passes through the waste heat boiler (air pre-heater) to release heat further, then passes the dirt remover; it is finally sent into funnel by induced draft fan and discharged into atmosphere. The heating surface consists of the monolayer ( double layer) coils so as to lay out enough heating area; such design reduces not only the resistance of the medium inside the heater but also the thermal load on the coil surface so as to ensure the safer usage of the heat transfer oils. The ceiling coil on the top of the radiant heating surface can protect the furnace top better and prevent it from being burned out. With the special design on the fire grate and furnace arch, the boiler can achieve the independent regulation on air volume, which makes the sufficient and full combustion. It can use a wide range of coal as fuel. It is very convenient to install the boiler because we only need to put the upper body and the below combustor together. So the installation period is very short. The factory     The workshop     Certifications       Related Products
