Biomass steam boiler combustion equipment adopts light chain grate to realize mechanical addition of biomass, and is equipped with drums and induced draft fans to realize mechanical ventilation. The biomass pellet boiler sales falls from the biomass hopper to the grate, and then burns after entering the furnace with the grate. The flue gas passes through the combustion chamber in the upper part of the rear arch, from the combustion chamber upwards through the rear shed tube smoke chamber, enters the first tube bundle to the front smoke box, and then is folded from the front smoke box into the second beam to the rear smoke box, and is drawn into the smoke by the induced draft fan. Tunnels, dust collectors and chimneys, and finally exhausted to the atmosphere.
This series of steam boilers has a high level of automation, with automatic regulation of boiler feed water, high and low water level alarms, low water level interlock protection, and interlock protection of induced and blower fans. The operation of biomass and slagging on the boiler is mechanized, which reduces the labor intensity of workers, and the auxiliary equipment is complete.
The control system of the automatic steam pressure adjustment system of the biomass pellet boiler enters the working state. When the necessary conditions for combustion are met, and the steam pressure in the pot is higher than or equal to the set pressure upper limit, the control system outputs a stop signal. Until it stops burning. When the system is at work and in normal operation, the feed water pump is started, the water pump works, and the water level differential pressure transmitter detects the water level signal to keep the water level of the drum stable and ensure the quality of the steam. Biomass pellet boiler sales water level adjustment instrument displays the boiler water level, and the water pump can also be manually controlled through the manual touch key on the control panel.
This series of boiler products are in the form of group (quick) installation, with compact structure, small footprint, short installation period, low installation cost, and low capital investment. The flue gas temperature at the tube sheet of the biomass boiler is low, the single-pass tube sheet of the flue tube is evenly heated, and the low stress of the tube sheet makes the boiler operate reliably and have a long service life. The heating surface layout is adequate and reasonable, the boiler heats up quickly, the pressure rises quickly, the output is sufficient, and the thermal efficiency is high. The grate is divided into air chambers for air intake, and the air volume of each air chamber is independently adjustable. The speed of the grate is stepless to adapt to a wide range of coals and fully burns. The electric control cabinet has overpressure, high and low water level alarms and interlocking protection devices, which are reliable and easy to operate.
The biomass pellet boiler sales have a larger furnace space than traditional boilers in terms of structural design. At the same time, the layout of the secondary air is very reasonable, which is conducive to the full combustion of biomass fuel. The control system adopts high-brightness display, with the famous brand PLC control system as the central control unit. Exchange information with boiler users through man-machine dialogue to realize fully automatic, safe and reliable operation of biomass pellet boilers.
