Boiler

Abstract

The invention discloses a boiler. The boiler comprises a housing, a burning material inlet, a smoke outlet and a water outlet, and is characterized in that a partition wall with an opening in the middle is arranged at the internal middle part of the housing; an afterheat recovery box is arranged at the rear part of the housing; a water collecting pipe communicated with the afterheat recovery box is arranged at the lower part of the housing; a boiler barrel is arranged at the upper part of the burning box; an ascending water pipe and a descending water pipe are arranged between the boiler barrel and the water collecting pipe; smoke pipes are arranged in the boiler barrel and the afterheat recovery box, and the rear end of the boiler barrel is in sealing connection with the upper end of the afterheat recovery box; a water outlet pipe is communicated to the front end of the boiler barrel; and an U-shaped pipe array is arranged in front of the opening. According to the boiler, the afterheat in the smoke is efficiently absorbed, the utilization efficiency of the heat is improved better, and the amount of inlet oxygen is greatly increased due to the long-distance smoke channel, so that burning efficiency of the fuel is increased; and the waste is avoided, and the energy consumption is reduced.

Description

technical field [0001] The invention belongs to the field of boilers, and in particular relates to a boiler. Background technique [0002] Boiler is a kind of energy conversion equipment. The energy input to the boiler is in the form of chemical energy in fuel, electric energy, heat energy of high-temperature flue gas, etc. After conversion by the boiler, it outputs steam, high-temperature water or organic heat carrier with certain 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 water boilers, which...

Problems solved by technology

In the current improvement, the usual method is to add a combustion chamber, or to use serpentine coil heat exchange tubes, but these measures only improve the heat exchange efficiency of the boiler, but also increase the complexity of the boiler structure, making The difficulty of boiler processing and use has increased a lot, which is not conducive to popularization
