The specific embodiment
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of granular fuel steam generator, comprise being positioned at and erect the flue that the body of heater of being located at a side and the bottom of being located at opposite side communicate with body of heater, described body of heater inner chamber is provided with bottom side fire grate and the upper strata fire grate that places on the fire grate of bottom side, described upper strata fire grate and upper of furnace body constitute first combustion chamber, and communicate with the feed hopper of top, the first combustion chamber lateral wall is provided with upper furnace door, described upper strata fire grate and body of heater bottom constitute second combustion chamber, the second combustion chamber lateral wall is provided with lower furnace door, second combustion chamber and body of heater flue adjacent wall are provided with the flue gas port, so that after flue gas and the steam generator heat exchange of being located in the flue body, efflux through flue.
The heat absorption pipe network that described steam generator comprises water tank and is connected with water tank, and be connected the steam output control valve on top.
Vertical heat absorption pipeline section perimembranous in the described heat absorption pipe network is provided with the fin to declivity.
Described water tank is provided with the water level controller in order to the work of control supply-water pump.
Described steam generator is provided with safety relief valve.
Burning and flue gas flow: biomass granule fuel adds from sequence number 13 Bunkers, enters sequence number 16 upper fire-gratings, and the fire grate angle that tilts helps biological particles and piles up to fire grate is anterior.Close after opening the igniting of sequence number 11 upper furnace doors, regulate vent aperture (fire door is provided with and can regulates air vent) on the fire door.Along with the continuous burning after-flame of the biomass fuel of upper fire-grating, the red-hot biological particles that diminishes gradually on the upper fire-grating falls to from upper fire-grating that lower fire grating burns away and after-flame.Along with the minimizing of biomass fuel on the upper fire-grating, the new granular fuel of sequence number 13 Bunkers is because the effect of gravity constantly adds to upper fire-grating automatically.Participate in the burning of fuel on the upper fire-grating after little air is come in from the air vent of sequence number 11 upper furnace doors, fire burns is separated out, to granular fuel through heating, drying, fugitive constituent from bottom to up.The unburned fugitive constituent of combustion product and part passes oxide layer, reducing zone in the upper fire-grating fuel bed of high temperature and flows downward to the fire grate lower combustion chamber and burn away.
The not enough air of lower furnace burning then can be supplied with by the adjusting air vent on the lower furnace door.The lime-ash in lower fire grating afterburnt is then cleared by undermost sequence number 9 shoot doors, and shoot door adopts drawer-type structure, operates extremely simple and convenient.
The high-temperature flue gas of the flue gas of upper fire-grating fuel combustion and lower fire grating burning merges together from the exhanst gas outlet on the right and enters steam generator body bottom upwards mobile, further wash away convection bank, be welded with unique V-arrangement deflector in the convection bank, the guiding flue gas becomes two serpentines evenly to wash away convection bank and collection case, strengthen the flue gas disturbance, improve traditional boiler heating surface heat-transfer effect more than 1 times.At last from smoke stack emission.
