Technical field
The present invention relates to Industrial Boiler Technology field more particularly to a kind of combustion furnaces.
Background technique
Traditional Industrial Boiler is heated using firewood, coal, diesel oil, natural gas as fuel.China is world today's fire coal
Industrial Boiler production and most commonly used country, however a major issue existing for coal-burned industrial boiler is the dirt to environment
Dye is serious.Pollution problem main cause existing for Industrial Boiler has the following: first is that technology generally relatively falls behind, fire grate, subsidiary engine
Deng universal poor；Second is that Industrial Boiler operation operational efficiency is low；Third is that coal quantity is not inconsistent with boiler design generally.With current state
Interior Industrial Boiler year consumption mark coal amount is about 3.8 hundred million tons of calculating, and China's coal-burned industrial boiler discharges about 6,400,000 tons of SO2,26.7 every year
Hundred million tons of CO2,3,500,000 tons of dust, these emissions are all pollution air main sources.
The selection of attention with people to environmental issue, clean energy resource is of increasing concern.Clean alcohol-based fuel is easy
Complete decomposition combustion, discharge product is steam and carbon dioxide, therefore energy-efficient subtract may be implemented in clean alcohol-based fuel boiler
Row.As it can be seen that using alcohol-based fuel as substitution fire coal, fuel-oil or fuel-gas boiler in industry, civilian (heating, bathing etc.) certain fields
It uses, for realizing that the target of energy-saving and emission-reduction carbon drop discharge of society has great significance.
Every one ton of alcohol-based fuel of burning relatively one ton of about 1.3 tons of coal reducing emission of carbon dioxide of burning reduces pernicious gas 150Kg.
Petroleum fuel is substituted comprehensively in industry, civil heat supply system field, forms the pattern that alcohol-based fuel uses.Compared with traditional fuel
Boiler, with alcohol-based fuel heat boiler combustion it is abundant, emission is pollution-free, and heat utilization efficiency is very high, thus its discharge have
The tail gas of heat is not used, that is, causes the waste of the energy.
It is filled with water heating application No. is the patent water pipe of CN201720265354.8, is filled with water heating compared to traditional cooking-pot type,
