Chain furnace knowledge The chain furnace is a fire-bed furnace with a wide range of applications, with a history of more than 100 years. At present, the capacity of domestic chain furnaces is 240t/h, and our company has achieved 160t/h hot water boilers.What should we do when problems occur in vacuum heat treatment? The chain furnace is a typical front-fed fuel boiler, and the grate moves slowly from front to back like a belt conveyor. The fuel descends from the coal hopper and falls on the grate, and travels with the grate. Air is introduced from below the grate from bottom to top, intersecting the direction of fuel supply. When the fuel passes through the coal gate, it is scraped to a certain thickness and then enters the furnace. After the fuel is radiantly heated in the furnace, it enters the combustion stage. 1. Chain belt grate: The shape of the grate pieces is like a link, and the whole grate itself is a wide annular chain belt formed by these "links" in series, and the chain belt is surrounded by the sprocket and supported on the front and rear axles.
