Gas-fired boiler

Abstract

The invention relates to the field of boilers, in particular to a gas-fired boiler. The gas-fired boiler comprises a boiler body, a gas treatment structure, an overhaul support structure and a hoisting structure; the gas treatment structure comprises a breather pipe, denitrification treatment equipment, S-shaped heat exchange plates, a box body, a water pool, a water pump, a first connecting pipe,a water inlet pipe, a water outlet pipe, a second connecting pipe and a water guide pipe; an exhaust port on the boiler body is in communication with an inlet of the denitrification treatment equipment through the breather pipe, an outlet on the denitrification treatment equipment is in communication with the box body through the breather pipe, and the bottom of the other side of the box body isconnected with the water pool. The gas-fired boiler has the advantages that treated gas flows through gaps among the three S-shaped heat exchange plates, the gas flow rate is slow, and the contact time with the surfaces of the S-shaped heat exchange plates is prolonged, so that the heat exchange effect is obvious, the temperature of exhausted gas is reduced, the temperature of the exhausted gas can be rapidly reduced, and the hot air exhausted heat pollution numerical value is reduced.

Description

technical field [0001] The invention relates to the field of boilers, in particular to a gas boiler. Background technique [0002] The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where the 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 thermal 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. [0003] At present, the content of dust particles in the exhaust gas of gas-fired boilers is relatively small. Generally, it is directly discharged after being treated by denitrification treatment equipment. However, the temperature of the exhaust gas is still very high. When multiple gas-fired boilers work at the same time, the direct discharge will cause the outside temperatu...

Problems solved by technology

[0003] At present, the content of dust particles in the exhaust gas of gas-fired boilers is relatively small. Generally, it is directly discharged after being treated by denitrification treatment equipment, but the temperature of the exhaust gas is still high. When multiple gas-fired boilers work at the same time, the direct discharge will cause the external temperature to rise and cause thermal pollution. aggravated
