Combustion boiler with fume exhaust pipe being replaced conveniently

Abstract

The invention discloses a combustion boiler with a fume exhaust pipe being replaced conveniently. The combustion boiler comprises a heating box, a cover plate is fixed to the edge of the outer wall ofone side of the heating box by bolts, an air exhaust opening is formed in the bottom end of the outer wall of one side of the cover plate, and an air exhaust pipe is welded to the inner wall of one side of the air exhaust opening. The fume exhaust pipe is connected to the end, away from the cover plate, of the air exhaust pipe in an inserted mode, equidistantly distributed connecting lugs are welded to the outer walls of one sides of the fume exhaust pipe and the air exhaust pipe, the connecting lugs on the fume exhaust pipe and the air exhaust pipe are fixed by bolts, an air inlet is formedin the top end of the outer wall of one side of the cover plate, and a gas pipe is welded to the inner wall of one side of the air inlet. According to the combustion boiler with the fume exhaust pipebeing replaced conveniently, staff can conveniently disassemble and clean the fume exhaust pipe, the replacement of the fume exhaust pipe is convenient, and the labor cost is saved; and the fixing andinstallation work of the fume exhaust pipe and the air exhaust pipe is facilitated, the stability of the fume exhaust pipe is improved, the combustion time and stroke of gas staying in the combustionboiler can further be increased, and the combustion efficiency and the heat conversion rate of the gas are improved.

Description

technical field [0001] The invention relates to the technical field of combustion boilers, in particular to a combustion boiler which is convenient for replacing smoke exhaust pipes. 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. Boilers that provide hot water are called hot wa...

Problems solved by technology

[0003] After the existing combustion boiler has been used for a long time, some impurities are easy to accumulate in the exhaust pipe, which needs to be cleaned regularly to prevent the pipe from being blocked and affecting the use of the boiler. Therefore, a combustion boiler that is easy to replace the exhaust pipe is urgently needed to solve the above problems
