Biomass Fired Boiler Combustion System

Biomass fired boiler combustion system is mainly composed of feed system, combustion system, ash blowing system, smoke air system, automatic control system.

The feeding system is composed of bin, vibrating feeder, screw feeder, screw pipe and so on. The BMF fuel processed in the factory is transferred to the silo by the belt conveyor, and then the BMF fuel in the silo is fed to the burner for combustion by the screw feeder. In order to ensure the stability of continuous feeding and material conveying, a vibrating feeder is connected between the bin and the screw feeder.

The combustion system consists of burners, fans, igniters and other components. The biomass fuel is first preheated in the burner and then transferred to the furnace by a fan for combustion. BMF fuels contain high volatiles, and when the temperature in the furnace reaches the volatiles' precipitation temperature, the igniter fuel can be ignited and burned rapidly under the condition of air supply. Burner temperature control is based on the internal temperature of the furnace, and its temperature is related to the amount of air supply during fuel gasification. The adjustment of boiler load is controlled by the adjustment of feed quantity. The flue gas after combustion enters the convection flue for heat transfer through the furnace, then enters the dust collector for purification treatment, and finally exhausts the whole combustion and heat transfer process.

Biomass boiler is equipped with automatic ash blowing device, which can regularly purge the furnace and smoke pipe to ensure no ash accumulation on the surface of the smoke pipe, so as to achieve safe and efficient operation of the boiler. The control system adopts high brightness display screen and famous brand PLC control system as the central control unit. Exchange information with boiler users through man-machine dialogue, realizing full automatic operation of BMF boiler.

The air supply system of this series of industrial boilers is arranged in an integrated manner with burners. The air is sent to the furnace by the blower through the burners to achieve the function of fuel transportation and combustion support. Under the action of an induced draft fan, the high temperature flue gas generated after combustion goes through convective heat transfer in the smoke pipe into a dust collector for purification, and is finally discharged by the induced draft fan through the chimney.

Parameters and technical requirements of 6-ton gas-fired steam boiler for hospital use

The 6ton gas-fired steam boiler is commonly used in hospitals, and its process requirements are as follows: Natural gas boiler: natural gas → burner → boiler → steam → sub-cylinder → steam point. Tap water constant pressure water supply → water softener → soft water insulation water tank → energy saver → boiler. Hospitals are densely populated places, so the requirements for boiler equipment and suppliers are relatively strict. Suppliers of 6ton gas boilers must have a Class A boiler manufacturing license, a pressure vessel manufacturing license, a Class 2 boiler installation, renovation and maintenance license or above. The equipment supplier shall be responsible for obtaining relevant certificates and fees such as the registration certificate for installation and use of boiler equipment. The water supply of this series of gas boilers is designed with a flue gas condensation recovery device to recover the heat energy of the flue gas, and the exhaust gas temperature is less than...

SZS Gas-Fired Horizontal Water-Tube Saturated Steam Boiler

The pipelines within the scope of the SZS watertube steam boiler only include the valves and pipelines from the flange of the return water check valve to the outlet valve and drain valve of the boiler body. Accessories include valves and gauges for the boiler body. Such as pressure gauges, air valves, spring safety valves, outlet and return valves, check valves, thermometers, etc. The SZS gas-fired steam boiler is equipped with a flue gas condenser at the tail of the boiler body, which reduces the flue gas temperature (<70°C), improves the boiler efficiency and reduces the harmful components in the flue gas. The boiler adopts micro-positive pressure combustion, and the furnace wall tube is a full-membrane wall structure. This series of boiler products has a certain pressure bearing capacity, and no smoke leakage and air leakage will occur when running under a slightly positive pressure state. The boiler is a self-contained boiler, which can shorten the installation period whi...

35 Tons SZS Gas Steam Boiler

The SZS gas fired steam boiler is equipped with a flue gas condenser at the tail of the boiler body, which reduces the temperature of the flue gas, improves the efficiency of the boiler, and reduces the harmful components in the flue gas. The szs gas boiler adopts micro-positive pressure combustion, and the furnace wall tube is a full-membrane wall structure. The 35ton gas-fired boiler has a certain pressure-bearing capacity, and there will be no smoke leakage and air leakage when running under a slightly positive pressure state. The boiler is a self-contained boiler, which can shorten the installation period while meeting the transportation size requirements. At the same time, the aluminum casing and the skeleton are transported and connected by bolts, which are convenient for disassembly and maintenance. The furnace of this series of boiler products adopts a model water-cooled wall structure, and the whole boiler adopts an air-tight inner shield with a fully enclosed welding s...
