Boiler device

Abstract

The invention relates to a boiler device. The boiler device comprises a boiler shell. A burning partition plate is arranged inside the boiler shell, and the boiler shell is divided by the burning partition plate into a burning cavity and an ash collecting cavity. A dust discharging hole is formed in the upper end of the boiler shell, a viewing window and a delivering pump are arranged on the side wall of the boiler shell, and the delivering pump is connected with one end of a delivering pipe. Two powder spraying covers are arranged on the delivering pipe. A plurality of heat collecting pipes are arranged on the upper side of the interior of the boiler shell and connected with a heat collector, and one end of the heat collector is connected with a heat transferring pipe. According to the boiler device, under the effect of the delivering pump, coal powder is loaded through high pressure and then sprayed out through the powder spraying covers, so that the contact area of the coal powder and air can be increased, burning is more sufficient, and the burning using ratio is increased; meanwhile, heat can be timely collected and transferred under the effects of the heat collecting pipes and the heat collector, the heat transmitting efficiency is improved, and heat losses are reduced.

Description

technical field [0001] The invention relates to the technical field of power plants, in particular to a boiler device. Background technique [0002] A power plant refers to a power plant that converts some form of raw energy into electrical energy for fixed facilities or transportation, such as thermal power, hydraulic power, steam, diesel or nuclear power plants, etc. [0003] 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 ...

AI Technical Summary

Problems solved by technology

[0004] Boilers are indispensable equipment in power plants. Existing boilers generally burn briquettes or briquettes directly. In this way, the contact area between briquettes or briquettes and air is small during the combustion process, which is insufficient in the combustion process. At the same time, the heat transfer efficiency of the boiler Low, resulting in a large energy loss of the boiler, at the same time can not clearly observe the internal combustion of the furnace
