Structural characteristics and working principle of hot blast stove

The RML type hot blast stove mainly includes two parts: the furnace body and the coal burner. The furnace body is a component used to isolate the combustion products in the furnace from the outside world and form a flue gas channel. The grate is the combustion part of the hot blast stove, which consists of a driving shaft, a driven shaft, a bracket, an ash-releasing device, an air regulating device, a furnace chain, a coal hopper, a front damper and a slag retainer.SWD SERIES PLC CONTROL 3D BEAMS DRILLING MACHINE The grate of the hot blast stove moves slowly from front to back at a speed of 2-20m/h through the speed-regulating motor through the reducer, and the coal in the coal hopper enters the furnace through the coal gate, and can be lifted by adjusting the coal gate Adjust coal seam thickness. The coal entering the furnace moves from front to back with the grate, and completes the stages of heating, drying, igniting, burning and burning out in sequence.Prevention method for grinding cracks of vacuum carburizing and quenching gears The finally formed ash is shoveled into the ash hopper by the slag removal plate (Eagle Iron) installed at the tail of the grate. In the belly frame of the grate, there is an air chamber that can adjust the air distribution in different areas.Pit Type Furnace Nitriding Process And Operating Procedures The air supply volume of each section of the air chamber can be adjusted separately with a baffle, and the air required for combustion is sent to each through the grate for ventilation The gap enters the coal seam to participate in the combustion reaction.SWD700 PLC CONTROL 3D BEAMS DRILLING MACHINE
