Abstract

The invention relates to the technical field of boilers, in particular to an auxiliary combustion device for a coal-fired boiler. There are three layers of load-bearing steel plates, the upper end of the L-shaped support rod is welded to the four corners outside the load-bearing steel plate, and each load-bearing steel plate is evenly spaced with multiple through holes. There are connecting rods, and the connecting rods and the baffles are vertically arranged. There is a curved steel pipe between two adjacent load-bearing steel plates, and the curved steel pipe is fixed on the load-bearing steel plate through a fixing ring. One side of the curved steel pipe is connected with a straight steel pipe, the straight steel pipe is movably connected with a U-shaped air pipe, and the U-shaped air pipe is connected with a blower. The invention solves the problem of insufficient coal burning in the existing coal-fired boiler.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to an auxiliary combustion device for a coal-fired boiler. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. [0003] Most of the existing small heating boilers in rural areas are coal-fi...
