Description
Technical field
The invention belongs to boiler plant field, particularly a kind of Detachable steam generator.
Background technology
At present, using waste heat from tail gas discharge recycling present situation, the equipment such as the burning of industrial and mining enterprises and oven dry produce a large amount of using waste heat from tail gas and are wasted.Flue gas waste heat recovery approach adopts two kinds of methods usually: one is pre-heated work pieces; Two kinds to be that preheated air carries out combustion-supporting.Smoke pre-heating workpiece need utilize the heat transmission equipment of larger volume to carry out heat exchange, is often subject to the restriction of Active workings.Adopt said method equipment mainly boiler carry out waste heat recovery.What is boiler? other thermal energy is become other working medium heat energy, production specifies that the equipment of the working medium of parameter and quality is called boiler.Boiler structure and operation principle pot: the water-steam system referring to boiler, be made up of equipment such as drum, down-comer, header, water-cooling wall, superheater and economizers.(1) task of boiler is that water is absorbed heat, and is finally changing into the steam of certain parameter.Its process is: feed water and squeeze into economizer by feed pump and absorb heat gradually later, temperature is elevated to the boiling point of drum operating pressure, becomes saturation water; Saturation water continues heat absorption in evaporation equipment (stove), when temperature-resistant, flash to saturated vapor; Saturated vapor is introduced superheater from drum and is superheated to set point of temperature gradually later, becomes qualified superheated steam, then arrives steam turbine acting.Drum: drum is commonly called as drum.What the drum of steam boiler was in-built is hot water and steam.Drum has certain water capacity, and with down-comer, water-cooling wall is connected, composition natural water circulation system, and meanwhile, drum accepts again the feedwater of economizer, to superheater conveying saturated vapor; Drum is the decomposition point of heating, evaporation, overheated three processes.Down-comer: effect is that the water in drum is continuously sent into lower collecting box, supply water-cooling wall, makes heating surface have enough quantity of circulating water, to ensure reliable operation.In order to ensure the reliability of water circulation, down-comer is all arranged in outside stove after drum is drawn.Header: also known as header.Be generally that diameter is comparatively large, the pipe of closed at both ends, is used for connecting pipe.Work to collect, mix and distribute carbonated drink and ensure that each heating surface reliably supplies water or collects water or the steam water interface of each heating surface.(being positioned at the lower collecting box of fire grate both sides, also known as anti-scorch header) water-cooling wall lower collecting box is all equipped with periodic blowdown usually.Water-cooling wall: water-cooling wall is arranged in surrounding or part in combustion chamber and is arranged in the middle of combustion chamber.It is made up of many tedges, to accept radiant heat transfer for main heating surface.Effect: the thermal-flame of dependence burner hearth and flue gas are to the radiant heat transfer of water-cooling wall, water (unsaturated water or saturation water) heating evaporation is made to become saturated vapor, because furnace wall inner surface is hidden by water screen tube, so temperature of furnace wall greatly reduces, make that furnace wall is unlikely to be burned.And slagging scorification and slag can be prevented again the erosion of furnace wall; The structure of furnace wall changed by cylinder, alleviates furnace wall weight.The form of water-cooling wall: 1. light pipe type 2. membrane type superheater: the auxiliary heating surface being steam boiler, its effect is when pressure is constant, from drum, draw saturated vapor, then through heating, makes saturated vapor become the superheated steam of uniform temperature.Economizer: be arranged in boiler back end ductwork, utilizes the equipment of the waste-heat boiler feedwater of flue gas, and its effect is exactly improve feed temperature, reduces exhaust gas temperature, reduces heat loss due to exhaust gas, improves the thermal efficiency of boiler.Desuperheating device: ensure steam temperature within the limits prescribed.Steam temperature regulates: 1, steam tempering (employing attemperator) 2, fume side regulate (adopt swing type burner) stove stove to be exactly the combustion system of boiler, are made up of burner hearth, flue, burner and air preheater etc.Operation principle: air is sent in air preheater the heat that absorbs flue gas and sent hot-flow flue to by pressure fan, is then divided into two strands: one is given pulverized coal preparation system and carries coal dust as First air and send into coal powder injection device, and another stock is directly sent to coal powder injection device as Secondary Air.Coal dust and primary and secondary air spray into burner hearth header combustion heat release through burner, and heat is passed to the radiation heating-surfaces such as the water-cooling wall of burner hearth surrounding with radiation mode, burning produce high-temperature flue gas then along flue stream through superheater, the equipment such as economizer and air preheater, heat is mainly passed to them with convection type, in diabatic process, flue-gas temperature constantly reduces, and finally sends into chimney by induced-draught fan and enters air.Burner hearth: burner hearth is surrounded by a furnace wall, for the principal space that fuel combustion is conducted heat well, its surrounding is covered with water-cooling wall.Burner hearth bottom is ash discharge cinder notch, and the furnace bottom of dry bottom furnace is the furnace hopper of the inclination being bent by front and back water screen tube and formed, and the furnace bottom of slag tapping boiler is the molten slag bath of level.Upper furnace is hung with pendant superheater, and burner hearth back upper place flue gas flows out the passage of burner hearth furnace outlet.Air preheater: be utilize the heat of boiler exhaust gas to add the heat-exchange apparatus of hot-air.It is contained in the vertical gas pass of boiler tail.Because technological difficulties are exactly with conventional boiler recovery waste heat, its volume is too large, usually because enough positions cannot be had to install, be limited to the defect of special equipment supervision, and waste heat exhaust emissions point is many, input cost weight, period of investment return limit for length, poor practicability.How to realize that one reduces costs, volume is little, by the restriction of enclosing interior supervision in pot specification, and facilitate installation and maintenance, the steam generator that can produce high-quality steam becomes the larger market demand.In addition, boiler belongs to pressure vessel, and the inner volume adopting water is generally more than 30 liters.
For example, the diesel engine that oil exploitation oil well uses discharges flue gas up to more than 300 degree, possesses very high recycling and is worth.But because discharged diesel oil flue gas is messy; And be difficult to by condition restriction water quality the requirement reaching boiler use; In addition, because the changed power of diesel-driven generator is frequent, the variations in temperature that tail gas is discharged is large, and conventional waste heat boiler is difficult to adapt to service condition.
