Said structure also can be matched with other components to possess other several functions including safety alarm function, etc.
Description
The present invention relates to a kind of under new boiler design theoretical direction, the new structure of design, novel combustion technology equipment, burning briquette and low heating value raw coal seriation boiler product.
China's boiler product has situation now:
The following steam boiler of the 20T/H that China now moves, hot-water boiler all are introducing external traveling-grate stoker, and back and forth double-deck water-cooled grate of the stripping fire grate of cant fire grate and China expert innovation and creation and fixed grate boiler are main.The deficiency that exists is that boiler coal bad adaptability, the thermal efficiency are low, undercapacity, big slag phosphorus content height, boiler grate sideslip, the easy scaling loss of fire grate, the fire grate fractional cold is big, smoke discharge amount is big, the big waste energy pollution of harmful gas emission environmental pollution atmosphere is serious.China's boiler product still rests on the level before 35 years.Do not satisfy the Environmental Protection in China state basic policy, the statutory standards of energy-conservation national law and requirement.The requirement of incompatibility China economic development.
Purpose of the present invention
Provide burning briquette and low heating value raw coal, environmental protection, energy savings, control pernicious gas atmosphere pollution, all qualified seriation boiler product up to standard of dust polluting environment.For industrial production provides steam, for people's lives provide heat supply heating heat energy thermal source.Put into practice the structure that two three ones of committees of ministry of materials of Machinery Ministry Ministry of Labour of planning commission of former national Economic and Trade Commission unite levelling reform raising China boiler product of formulation, the boiler design theory that innovation and creation make new advances, instruct New-type boiler product development Development and Production, realize that China's boiler product upgrades Huan Shi.Improve the comprehensive technical indexes performance and the roman level of boiler product.
The design theory that the present invention proposes
Free carbon molecule coal gasification in the fire coal, the fixed carbon molecule solidifies carbonization in the fire coal, and coal gas and fixed carbon, carbonized carbonaceous divide the combustion cofiring to mix combustion.The coal-fired burning under the condition of high temperature adds quantitative steam water and water, short coal molecule and hydrogen molecule when steam and water reduction decomposition, and oxygen molecule carries out the chemical breakdown reduction.When at high temperature carrying out chemical reaction, suppresses hydrocarbon oxygen molecule generation and the discharging that control destroys nitride sulfide.
Foundation of the present invention
The present invention to be finishing the mini-test of correlation technique project, and obtains the basis that authentic data is product design.
According to boiler product population theory and notion, pot is that pressure-containing parts is a heat-exchange apparatus.Stove is that the combustion apparatus of boiler is the conversion equipment of carbon energy.The key problem in technology of boiler product is to improve to reform the more combustion technology and the equipment of new boiler.Promptly be the complex art economic criterion and the level of the advance decision boiler product of combustion technology and equipment.
According to the national environmental protection state basic policy energy and air contaminant treatment law decree rules.Boiler product quality monitoring, law, decree, rule, technical standard and the regulations of country's promulgation.
According to China's abundant coal resource, the hundreds billion of ton of China's coal reserves, sincerely in the Inner Mongol, Shanxi, Shaanxi, Gansu, Ningxia, Xinjiang verifies brown coal band reserves and can use 200 years for the whole nation.
The invention of moulded coal is to adequately protect to utilize exploitation China coal resource, realizes improving boiler complex art economic indicator.The best fuel of control pernicious gas contaminated environment atmosphere pollution.The technology of China's moulded coal occupies first place in the world.Country has built tens of moulded coal production lines in planned economy age throwing huge fund and can use for the different coals of national zones of different in the whole nation.
The present invention finishes in the following way
Boiler is provided with upper drum, lower drum, and the side collection, convection bank constitutes the water pipe structure pot.
Boiler is provided with ferrous metal skeleton fire grate and high temperature resistant, and high strength engineering ceramics spare is combined as fixed grate boiler under the high temperature.Boiler is provided with being made up of track, tilting bar, electrodeless transmission system and closed system of new structure, the V-type stoker boiler is provided with steam generator and injecting type water drenching device in boiler, steam and water are injected in the reducing zone and flame of boiler main combustion chamber burning, arch is set builds wall and flame is formed spray regime directly wash away tube bank, cancel big volume burner hearth.Be provided with 1
