Application method.
Background technology
It is well known that many industries are required for using steam in process of production, especially in recent years, as people are to steaming
The wilderness demand of vapour, the application of steam boiler are also more and more extensive.Common steam boiler includes four kinds, i.e.,：
(1) coal-burning boiler；Coal-burning boiler is most traditional, although coal-burning boiler is faced with the border gradually eliminated now
Condition, but we can not deny the important function that coal-burning boiler was taken on and played in the past.In presently coal-burning boiler still
It is so most popular, the area especially in some present economics of underdevelopment.For coal-burning boiler, use cost compared with
It is low, it is adapted to the relatively backward area of economic development, but precisely due to sulfur content is larger in coal body, after burning the shortcomings that its is maximum
Emission can be caused seriously to pollute to air, while substantial amounts of place is also taken up during use, and dust is also more.
(2) biomass boiler；Biomass boiler is a kind of environmentally friendly boiler of comparison, and occupation rate is used in current boiler market
It is and higher.The fuel of biomass boiler belongs to reproducible green energy resource, and wide material sources be mainly agricultural crop straw,
Wood chip, bark etc., because it derives from biomass energy, the feature of environmental protection is also high, and widely using for biomass steam generator can be with
Reduce the dependence to fossil energy.Although its advantage is more, design in use, it is seen that：Initial input cost compared with
Height, substantial amounts of space is also required to when in use.
(3) oil burning boiler；The use of oil burning boiler in recent years is also than wide, and in use, fuel oil burning is rapid,
And burner hearth coking problem is not present, furnace volume heat release rate is higher, than coal-burning boiler height by about one time；But due to its fuel
Price it is of a relatively high, the financial burden also relative increase for general enterprises, the transport of fuel oil, the danger of storage in addition
Height, easily there is accident.
(4) gas fired-boiler is because the fuel of gas fired-boiler is natural gas, efficiently, environmental protection turn into the great advantage of combusting boiler,
But the use of gas fired-boiler is to have ready conditions limitation, it is necessary to the ground that gas pipeline is opened can be enjoyed just now, and some compared with
The place of backward obstructed combustion gas, it is that can not use natural gas.
By above-mentioned analysis, it is seen that, each steam boiler all suffers from some problems during design, use, thus

System is limited among one big drum again, and anti-pressure ability is very strong, is overcome the drawbacks of conventional vapor boiler tube bursting, is greatly improved
The safety coefficient of steam boiler, this is the key point of the present invention.
4th, two drum both ends and the end face of boiler body not in one plane, and grow away one section, so design plus
Heat exchanging process has been grown, has improved heat-transfer effect, has been very reasonable science.
5th, conventional vapor boiler does not have not pressure-bearing water system, and fire resisting is all used outside the pressure-bearing water system of all catalytic combustion thermal energy
Material is replaced, and is greatly to waste for the energy.But the place of catalytic combustion thermal energy is all set to by the present invention
Independent, the water system of pressure-bearing, the drum for producing steam of making a living do not feed 40 DEG C or so of hot water, significantly increase steam production,
Thermal energy is fully utilized.
6th, structure design is simple, in production process, drum, dust deposited case, diversion box, smoke separating box and support in steam boiler
All parts can batch production Prefabrication, quick assembling, production and assembly efficiency can be greatly improved, and realize standardization,
Modularization, substantially increase quality standard.
7th, the effect of drum is using the thermal energy conducted in the steel pipe vertically set up among drum, will pass through in boiler and add
Water after heat is changed into steam, and overall construction design is more reasonable, makes full use of the temperature of flame and flue gas to enter each water layer
Row heating, thermal energy conversion efficiency are high.
8th, quirk, lower quirk, upper flue, the design method of lower flue in setting, the motion row of flame is on the one hand added
Journey, water is fully heated, on the other hand effectively the waste heat of fire smoke gases can also be made full use of, overall heat energy utilization
Rate is higher, and security is ensured.It is discharged into addition, being extracted out tail cigarette by means of air-introduced machine within the deduster of boiler exterior setting
Carry out dedusting operation, it can be ensured that meet the requirement of environmental protection during exhaust emissions.
9th, automaticity is higher, is provided with automatic control system, and the whole service process to boiler automatically controls,
Enormously simplify the operation of boiler, and ensure that the operation of high-effect high-quality, automatic alarm, ensure that it is safe for operation, significantly
Reduce the labor intensity of operating cost and operation；And the networking control with remote monitoring center is set, is extensive, big model
The horizontal combination operation and maintenance management enclosed lay the foundation.
