Background technology
Boiler is a kind of energy conversion, and the energy inputted to boiler has chemical energy, electric energy in fuel, boiler output
Steam, high-temperature water or organic heat carrier with certain heat energy.The original meaning of pot refers to the water container heated on fire, and stove refers to burning
The place of fuel, boiler include pot and stove two large divisions, and caused hot water or steam can directly be industrial production and people in boiler
Heat energy needed for people's livelihood work offer, mechanical energy can be also converted to by Steam Power Equipment, or again be turned mechanical energy by generator
It is changed to electric energy.The boiler for providing hot water is referred to as hot-water boiler, is mainly used in living, also there is a small amount of application in industrial production；Produce
The boiler of steam is referred to as steam boiler, is often simply called boiler, is used for thermal power station, ship, locomotive and industrial and mining enterprises.
The main operational principle of boiler is that a kind of waste heat using in the heat energy discharged after fuel combustion or industrial production passes
Pass the water in container, make water reach required for temperature or certain pressure steam heat power equipment.Boiler is in " pot " and " stove "
Two parts are carried out simultaneously, and water enters after boiler, and boiler heating surface feeds water the heat transfer of absorption in boiler circuit, makes water
The hot water or generation steam of certain temperature and pressure are heated into, is brought out applying.In combustion apparatus part, fuel combustion is constantly put
Go out heat, high-temperature flue gas caused by burning transfers heat to boiler heating surface, and self-temperature gradually drops by the propagation of heat
It is low, finally discharged by chimney.
The sorting technique of boiler is a lot, can be by the purposes point of boiler, structure that can also be by boiler, fuel type point,
It can also classify by water circulation form, pressure.1st, by boiler purpose classification：Boiler can be used as thermal power boiler and heat supply pot
Stove.Power boiler includes station boiler, ship boiler and locomotive boiler etc., is mutually applied to generating, ship power and railroad traction,
Heating boiler includes steam boiler, hot-water boiler, heat pipe boiler, hot-blast stove and heat-carrier heater etc., be correspondingly made available steam,
Hot water, hot blast and thermophore etc.；2nd, classify by structure of boiler body；By boiler structure point：It is broadly divided into multitubular boiler and water pipe
Boiler, multitubular boiler include vertical boiler and horizontal boiler, and water-tube boiler includes tranverse water tube boiler and vertical water pipe boiler；3rd, by pot
Furnace fuel type classification：By boiler coal-burning boiler, oil burning boiler and gas fired-boiler and coal-fired pot are categorized as with fuel type
The upgrade technique of stove, substitute products-pulverized-coal fired boiler, gas double boiler etc. of oil and gas stove.Coal-burning boiler can be with by combustion system
It is divided into grate firing boiler, room combusting boiler and boiling boiler, newest fuel is alcohol-based fuel boiler, will greatly reduce coal-burning boiler to big
The pollution in compression ring border；4th, classify by boiler capacity：Evaporation capacity is referred to as miniature boiler, evaporation capacity more than 75t/h's less than 20t/h's
Referred to as large-sized boiler, what evaporation capacity fell between is referred to as medium-sized boiler；5th, classify by boiler pressure：Below 2.5MPa pot
Stove is referred to as low-pressure boiler, and more than 6.0MPa's is referred to as high-pressure boiler, and what pressure fell between is referred to as medium-pressure boiler, in addition,
Also superpressure boiler, subcritical boiler and super critical boiler；6th, by boiler water cycle formal classification：By boiler water cycle form
Natural circulation boiler and forced circulation boiler can be divided into（Including direct current cooker）；7th, classify by device form：It is divided into fast-assembling pot
Stove, semi-packaged boiler and boiler in bulk, in addition, the also form such as wall hung gas boiler, vacuum boiler and module boiler.
Whole fire grate mainly includes two parts of framework and fire grate segment, and fire grate segment generally cylinder iron manufactures, after assembling piece and
Necessary ventilation gaps are kept between piece, and the draft chamber for the separation that can adjust air quantity is set below toward contact in fire grate,
So as to air by gap incoming fuel layer burn, the lime-ash after burning-up manually or mechanical means discharge, fire grate have it is fixed,
