Novel domestic energy-saving and environmental-friendly heating stove

Abstract

The invention discloses an energy-saving and environmental-friendly heating stove which comprises a stove body. The stove body is internally provided with a hearth and a multi-return-stroke reversal combustion chamber communicating with the hearth and is provided with a fuel feeding inlet leading to the hearth and a smoke box leading to the reversal combustion chamber. The smoke box is internally provided with smoke waste heat recovery devices and is provided with a smoke discharge barrel leading to the outside. The stove body is further provided with a water jacket wrapping the outsides of the hearth, the multi-return-stroke reversal combustion chamber and the smoke box. According to the energy-saving and environmental-friendly heating stove, the purpose of energy saving and environmental protection is achieved through fuel granularity control and smoke waste heat recovery, tail gas is filtered, pollution is reduced, and the energy-saving and environmental-friendly heating stove is simple in structure, low in cost and convenient to use.

Description

technical field [0001] The invention relates to a device in the field of small coal-fired boilers, in particular to a new energy-saving and environment-friendly heating furnace for household use. Background technique [0002] Household heating stoves generally use coal as the main fuel, and a few use briquette coal, firewood, and biomass pellets as fuel. Unprocessed raw coal. In recent years, smoggy weather has occurred frequently, and even smoggy weather has become the norm in some areas. According to the analysis of the Ministry of Environmental Protection, every ton of high-volatile raw coal burned in northern rural areas will emit more than 2.5 tons of carbon dioxide, and more than 150 kg of coal other pollutants. The emission of one ton of loose coal combustion is equivalent to the pollutants emitted by 5 to 10 tons of power plants. During the period of heavy pollution, the particulate matter emitted by fossil fuel or biomass combustion increases significantly, and t...

AI Technical Summary

Problems solved by technology

Due to the large difference between the price of other clean energy and coal-fired prices, coal-fired heating stoves will still be the first choice for northern household heating for a long time. The problems of low coal-fired utilization rate, low thermal energy utilization rate, and large pollution have become an important task for energy conservation and emission reduction, and have very important social value
