The utility model has following feature:
The utility model is the important component part of clean coal technology, the scope of application of high energy charcoal alcohol fuel slurry (water-coal-slurry, coal, methyl alcohol coal slurry) is extended on medium and small micro-boiler kiln and uses, the low-cost high-efficiency clean fuel problem of medium and small micro-boiler kiln of enormous amount is resolved, make the burning and exhausting of medium and small boiler meet discharging standards, the technical bottleneck that clean coal technology is used on medium and small micro-boiler kiln is broken through at all.
The utility model uses inward eddy pressure atomized fog jet (i.e. the first pressure atomized fog jet 200 and the second pressure atomized fog jet 802), successfully solves solid-liquid two working medium, adopts the phenomenon occurring in the pressure atomization of air pressure system to be separated in tradition.The force (forcing) pump 102 of fuel feed system 100 can adopt membrane pump, and sprayed by pressure atomized fog jet after being pressurizeed by high energy charcoal alcohol fuel slurry, pressure atomized fog jet adopts wear-resisting tungsten alloy material to make, and has good anti-wear performance.This combustor can support two pressure atomized fog jet system, by the spray volume of the solenoid control fuel of Control Nozzle pipeline, can well save fuel in combustion.Two inward eddy pressure atomized fog jets in the utility model, its nozzle flow can be equally large, also can be greatly different.Determine according to user load situation, if the fluctuation of load is little, more steadily, the nozzle that two equally large can be selected.If the fluctuation of load is large, then select big fire nozzle large, the configuration that little fire-fighting mouth is little.
High energy charcoal alcohol fuel slurry special pressure spray burning machine of the present utility model, combustion controller 600 is adapted to the combustor control system of the special combustion process exploitation of high energy charcoal alcohol fuel slurry, support the light sensor of mixed spectra, temperature sensor, detected temperatures height switches large and small fire.Spray nozzle clogging and automatic alarm is judged by pressure and flow monitoring.Realize automatic ignition, automatic ignition time flame-out, automatic protection functions of lighting a fire not.Rinse-system automatic control function, needs automatically to open flushing when rinsing.Airdoor control function, when large and small fire switches, opens damper regulator.
Rinse-system 700 in the utility model, line clogging problem when solving start and stop or in work.Rinse-system comprises membrane pump, check valve.Because high energy charcoal alcohol fuel slurry still leaves fuel slurry when shutting down in pipeline, under the high temperature of burner hearth, methyl alcohol evaporates gradually, leave solid, nozzle and line clogging phenomenon can be there is again, fuel residual in pipeline and nozzle can be gone out by self-stripping system, prevents the generation of clogging.Rinse-system 700 of the present utility model can play at any time when system needs, and ensures that combustor also can prevent line clogging at work.
Air supply device 400 in the utility model is blower fans, comprises fan main body 401 and damper 402, and damper 402 uses two gear air doors, coordinates large and small fire adjustable.Air door drives and adopts motorized motions.
In the utility model, combustion condition sensor 500 comprises flame detection sensor, because namely the burning spectrum of high energy charcoal alcohol fuel slurry be different from methyl alcohol, be different from coal dust again, be provided with the spectral mixing of the two, therefore have employed the light sensor of applicable mixed spectra especially, as the detecting sensor of flame, certainly, described combustion condition sensor 500 can also comprise the sensor such as temperature, pressure.
The workflow of a kind of combustor of the present utility model is as follows:
1, system electrification, control system enters self-inspection state, and whether detection system is normal, if abnormal, system can automatic flame detection sensor, if exception sends warning, the alarm lamp on control panel is bright.
