Fuel oil and fuel gas steam boiler

Abstract

The invention discloses a fuel oil and fuel gas steam boiler. The fuel oil and fuel gas steam boiler comprises a combustion furnace body, a turbocharging fan above one side of the combustion furnace body and a chimney arranged above the other side of the combustion furnace body; the combustion furnace body comprises a combustion chamber and a water storage chamber, the combustion chamber comprisesa combustion channel, a reversing chamber and a combustor, a first return pipe, a second return pipe arranged above the first return pipe, a steam output valve arranged above the water storage chamber and a water inlet pipe arranged above the water storage chamber are arranged in the water storage chamber, through the combustion chamber composed of the combustion channel and the reversing chamber, oil and gas can be sufficiently combusted, and the effects of energy saving, environment friendliness and heat increasing are achieved; through the first return pipe and the second return pipe, thesmoke gas conveying path can be prolonged, the heat exchange effect is improved, the first return pipe and the second return pipe are rapid in heat conduction, the resource waste caused by direct discharging of heat along with smoke gas can be reduced, and the boiler is suitable for boiler heat recycling.

Description

technical field [0001] The invention relates to a fuel gas steam boiler. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input into the boiler can be chemical energy, electric energy, etc. After being converted by the boiler, it outputs steam, high-temperature water or organic heat carrier with certain heat energy, which can be used in power stations, ships and locomotives etc., making it play an irreplaceable role both in industry and in life; due to the scarcity of coal energy, traditional coal-fired boilers are now being phased out, and environmental protection bureaus around the world require coal-fired boilers to be converted into clean energy , The emerging natural gas is a clean energy with low cost, high combustion rate and low emission, which can meet environmental protection requirements. [0003] Traditional oil-fired gas-fired steam boilers are mostly vertical, and adopt a two-return structure consisting of a lower f...

Problems solved by technology

Due to the limitation of the structure, the flow of the flue pipe is short, the flue gas flow rate is slow, and the heat exchange effect is poor; at the same time, due to the large water capacity in the furnace, the fuel consumption is large when the boiler is started, and the fuel waste is serious when the heat exchange effect is poor.
