Biomass fuel boiler is a kind of boiler, is to biomass energy as a fuel boiler called biomass boiler. Biomass fired boiler installation cost is low, heating safety, heating material sources are wide, never dried up, everywhere desirable (such as: chaff, corn stalk, rice stalk, wheat). Biomass pellet boilers working pressure is small, can be used for bathing, heating and so on. At the same time, it is also suitable for greenhouse heating, large area heating, small and medium-sized hotel use, not subject to seasonal restrictions.
This boiler product adopts the fast furnace combustion mode, flammable wood chips, wood blocks, wood, bark, bamboo, clothing bags enterprise waste, broken agricultural straw and so on. The boiler adopts arch tube-sheet and threaded smoke tube to form the drum, which makes the cylinder change from quasi-rigid body to quasi-elastic body structure, eliminates the tube-sheet area and reduces the stress. In order to solve the problem of crack in tube-sheet, the pipe in tube-sheet is changed from two return to single return.
Biomass pellet boilers uses threaded smoke tube to enhance heat transfer, improve the heat transfer coefficient and thermal efficiency, because the flue gas in the tube has the disturbance effect. Smoke pipe is not easy to accumulate ash, play a role in self-cleaning. Biomass fired boilers adopts high efficiency heat transfer threaded smoke tube, which obtains the effect of heat transfer enhancement, achieves the characteristics of boiler temperature rise, fast pressure boost, and improves the thermal efficiency of the boiler.
When the biomass fired boiler is running, the fuel is sent to the top of the furnace by the feeder, and then sent to the furnace by the spiral feeder, evenly scattered on the grate, here because of the effect of high temperature flue gas and a preheating, drying, ignition, combustion, the process of precipitation of a large number of volatile, burning violently. This thread smoke tube boiler soot cleaning ability, threaded pipe load half of flue gas flow rate is still can be in more than 8 m/s, more than in the velocity of threaded pipe produced by the ash removal ability (rotation of the sets of high-speed air flow will be lower than half load grey swept away), which sets ash phenomenon, make the type boiler in a constant output unchanged, the efficiency in the operation of all the year round.
Biomass pellet boilers is a kind of biomass boiler with variable arch structure and low nitrogen oxide. Including the front, middle and back three sections of the air chamber, chain or reciprocating grate, by the front supply, the combination of the rear arch. At the bottom of the pot room arrangement in the wind and the wind chamber and achieve segmented with the wind, before and after the period of the wind room decorate a grate, above the furnace front before installing upward sloping arch tunnel, after the furnace after installation tilt of the arch, this combination of biomass fuel boiler and combustion characteristic, make to adapt biomass species widely, boiler burning degree good, the effect of pollution discharge bottom.
