Fig. 2 is the side view of living beings heat-conducting oil furnace.
Detailed description of the invention
As depicted in figs. 1 and 2, biomass heat-conduction oil oven comprises the burner hearth 8 of firing biomass fuel, conduction oil body 13 is installed above burner hearth 8, the profile of heat-conducting oil furnace body 13 is a cylindrical shape furnace wall 5, inside, furnace wall 5 arranges the inner coil pipe 6 and the outer coil pipe 7 that carry out heat exchange for flue gas and conduction oil, the feeding mouth of burner hearth 8 installs feed screw 1, the entrance of feed screw 1 is communicated with stove storehouse, stokehold 3, reciprocal grate 10 is set below burner hearth 8, conduction oil body upper part arranges smoke-box 4, the outlet flue of smoke-box 4 is communicated with air preheater 12, burner hearth 8 sidewall is communicated with primary air nozzle 9 and overfiren air port 11, burner hearth 8 front wall bottom arranges air inlet 2.
The process of biomass heat-conduction oil oven firing biomass fuel is: fuel is thrown into after on fire grate, and its temperature starts to raise, and dries out and becomes dry; When fuel temperature reaches 100 ~ 105 DEG C, volatile matter starts to separate out, and the structure of fuel particle starts to become fluffy; When fuel temperature reaches 220 ~ 300 DEG C, fuel takes fire, and when temperature reaches 800 ~ 1100 DEG C, the burning of charcoal stops.
The process that fire grate occurs can be divided into: the endothermic reaction (dry and pyrolysis) and exothermic reaction (burning).Because biomass fuel has very high volatile matter, their chemical energy is mainly discharged in burner hearth inside.Volatile matter takes fire when 500 ~ 600 DEG C in burner hearth.Flame is very long, and the vertical type of furnace of the utility model is well suited for the burning of biomass fuel.
According to the combustion characteristics of biomass fuel, the effective measures improving the combustion efficiency of biomass fuel are: the supply of air is indispensable.Except supplying except First air bottom fire grate, also to additionally provide rational Secondary Air for volatile combustion, for this high volatile fuel Secondary Air often higher than First air.For biomass fuel boiler, due to biomass fuel easily catch fire, fugitive constituent is high, it is short to burn the time, and only need a large amount of oxygen in high temperature combustion zone, if the uniform requirement that can not meet biomass fuel and burn completely of Secondary Air, then can produce excess air or form black smoke in running.
1, heat-conducting oil furnace body
Conduction oil body adopts vertical structure.Conduction oil body is made up of the inner coil pipe arranged in furnace wall and furnace wall and outer coil pipe.Inner coil pipe (1 pipe upwards spirals and forms the coil pipe of a large diameter multi-turn) and outer coil pipe (outwards screw out with 1 pipe and then upwards spiral and form the coil pipe of the multi-turn of a larger diameter) compose in parallel exhaust gases passes.Form radiation of burner hearth heating surface in whole inner coil pipe, inner coil pipe and outer coil pipe, between outer coil pipe and furnace wall, form burner hearth convection heating surface.Furnace roof cover plate and fixture thereof can be opened fast, make cleaning, maintenance, easy to maintenance.
Fuel the generated high-temperature flue gas that burns on fire grate enters inner coil pipe (radiant tube component) after radiation heat release, temperature is down to about 350 DEG C, entered in outer coil pipe (convection tube assembly) by upper furnace and carry out convection heat transfer, temperature is down to about 230 DEG C, then enter air preheater, then enter air through chimney.Low Temperature Thermal carrier (conduction oil) enters oil return header, flow through inner coil pipe (radiant tube component) and carry out rotating jet flow, flow through outer coil pipe (convection tube assembly) again and carry out convection heat transfer, form high-temperature heat carrier (conduction oil) and import fuel-displaced header, be transported to heating equipment and carry out heat exchange (heat release), then be pumped into oil return header through forced circulation, reheat, constantly circulate.Calorific value distributes rationally, arranges enough heating surfaces, ensures thermal power.
2, air preheater
Air preheater is made up of many straight steel pipes.Flue gas is walked in pipe, and air is walked outside pipe, flue gas 1 flow process, and air is done two and turned through 180 degree, around being separated into 4 flow processs.Through heat convection, overfiren air port is caused through overfire air fan by the air heated, tangentially boiler furnace is entered through overfiren air port, form imaginary circle, the burning cloth wind of boiler furnace fuel, is mainly arranged in boiler furnace first half, adapt to the needs of fuel combustion, by adjusting the aperture of air door, reaching reduction excess air coefficient, forming the flame of vigorous combustion.
3, air inlet
Air inlet is used for blowing into burner hearth to by biomass fuel, and make burner hearth cloth even, prevent tempering, powder blows to burner hearth rear portion, makes furnace flame form " S " type torch, increases fuel at residing time in furnace, meets the needs that biomass fuel fuel burns.
4, fire grate
Combustion apparatus adopts the reciprocal grate with angle of function admirable, and boiler wind speed adjustment adopts special Secondary Air arrangement.Configure primary air nozzle below burner hearth, and configure overfiren air port with fire grate plane plan furnace left and right sides, be beneficial to the burning of biomass fuel and burn.Ensure that the efficient stable of boiler runs.Thermal oil heating piping system adopts the forced circulation mode being convenient to safe operation, and closed circuit is very simple.This heat-conducting oil furnace structural configuration is compact, safe and reliable to operation.
5, Secondary Air
The overfiren air port that burner hearth left and right sides is parallel with grate surface, from air nozzle ejection as shown in the figure, tangentially form an imaginary circle at hearth combustion center, stir furnace gas, make it Homogeneous phase mixing, burn volatile matter, reduce furnace temperature, and make inner flue gas of the stove produce vortex, extend the flying dust and the stroke of fly ash combustible material in stove that suspend, flying dust and fly ash combustible material are reduced further, and its reasonable Arrangement uses and flying dust amount can be made to reduce, and fly ash combustible material is reduced.In addition, to suspension combustible and volatile matter, supply enough air, be conducive to fuel and burn, improve boiler thermal output, be beneficial to and reduce the initial smoke density of boiler, be conducive to the energy-conservation and environmental-protecting performance improving boiler.
