Description
Technical field
The present invention relates to the heating equipment technical field, relate in particular to a kind of special boiler that heats and have condensation by flue gas.
Background technology
Boiler is a kind of heating equipment, it is to utilize coal, oil or gas for fuel, produce heat through burning and produce steam or hot water, flue gas, slag that coal produces pollute the environment, and the harm people's is healthy, and the processing of combustion technology and flue gas is comparatively complicated, oil gas type fuel is easy to carry and use, guaranteeing substantially not produce environmental pollution under good burning condition, calorific capacity is high.In recent years, because the Methods of Oil-Gas Fired Boiler volume is little, automaticity is high, easy for installation, be widely used, and a large amount of primary energy of urban heat supplying boiler consumption, the pollutant of amplification quantity side by side, the heating boiler of China mainly be take fire coal as main traditionally.Raising along with the urban life level, in order to improve urban air-quality, use clean energy resource to become a kind of trend, in these years, our country has found and has exploited a large amount of natural gases, set up the heavy construction of transfering natural gas from the west to the east, some areas are (as Beijing, Xi'an) be defined in the inaccurate coal heating boiler of setting up again in urban district, and recommendation natural gas boiler energetically, for fear of the back-end surfaces cold end corrosion, traditional coal heating exhaust gas temperature is usually above 150 ℃, steam boiler is even higher than 200 ℃, after adopting natural gas, most hot-water boiler exhaust gas temperature is between 140～200 ℃, this has not only expended a large amount of energy, and improved the operating cost of boiler, the boiler that the natural gas of take is fuel, the flue gas of discharge has 150 ~ 250 ℃ of quite high temperature, it contains approximately 15% ~ 19%(volume of steam), the main carrier of flue gas heat.If the exhaust gas temperature of boiler is dropped to enough low level, the steam that is so superheat state in flue gas will condense and emit the latent heat of vaporization, the boiler that the latent heat of vaporization in flue gas is recycled is called condenser boiler, there are the defects such as efficiency is low, equipment is perishable, UTILIZATION OF VESIDUAL HEAT IN facilitates not in time in traditional flue heat exchange design, cause boiler to use the decline of whole efficiency, wasted a large amount of energy.
Summary of the invention
The applicant, for the shortcoming existed in above-mentioned prior art, provides a kind of extraordinary condenser boiler,
