Abstract

The invention discloses an energy-saving and environmentally-friendly boiler, which is characterized in that an interlayer-type water jacket is arranged between a hearth wall and a boiler shell body; three flue beams comprising a plurality of round exhaust pipes are vertically arranged in a water tank of the boiler; and the air and the fume in the boiler sequentially pass through a flue beam A, a fume and dust tank B arranged in the water tank and a flue beam C, enter a flue outlet, and are pumped by an exhaust fan to enter a chimney so as to be discharged into the air. The energy-saving and environmentally-friendly boiler has the advantages of reasonable structure, high thermal efficiency, sufficient combustion, no black smokes, good smoke and dust removing effects, environment friendliness and energy conservation. The temperature of smoke discharge is as low as about 35 DEG C, the thermal efficiency is high, and 45% to 50% of coal can be saved. The energy-saving and environmentally-friendly boiler can be widely used for heating, domestic water, steam production, bath and the like.

Description

technical field [0001] The invention relates to a boiler, in particular to an energy-saving and environment-friendly boiler. Background technique [0002] At present, there are various boilers on the market, and most of them use coal as fuel. In order to improve the heat utilization rate of boilers, reverse combustion technology is generally used in boiler design. The latest reverse combustion design of the reverse combustion boiler is to use the double return flue to absorb the heat of the smoke for a second time, which reduces the temperature of the exhaust gas and increases the heating area of ​​the water, thus achieving the effect of energy saving and coal saving. However, there are still high boiler exhaust gas temperature, large heat loss of flue gas, low boiler thermal efficiency, insufficient output, resulting in high ambient temperature; at the same time, there is still a small amount of black smoke, which fails to meet environmental protection requirements.
