It is well known that water is heated in a boiler barrel to become steam, and fire gives off heat in the furnace, which is the principle of a steam boiler. There are many forms of steam boiler, today we will take 4ton biomass steam boiler as an example, to specifically talk about its principle and structure. Zozen Boilers biomass steam boilers manufacturing quality and reliable, stable operation safety, reasonable price, welcome everyone to come to advisory procurement.
Biomass fired boiler is a boiler with water wall. Between the pot barrel and the lower box, there is a descending tube and a water-cooled wall tube, forming the frame of the combustion chamber. There is a steam separator at the top of the drum to reduce the water vapor carries out. The heating surface of the pot is the lower part of the pot, the water – cooled pipe and the firework pipe.
The combustion part of 4ton biomass boiler is composed of a chain grate and a driving device, plus a combustion chamber formed by the pot frame on the grate frame. The surrounding refractory material, the fuel is entered by coal scuttles, and the coal gate is used to control the thickness of coal seam and seal the air in front. The lower part of the combustor is where the blast enters. This kind of boiler has great resistance and requires forced blast. From the back of the boiler, the flue gas goes forward by the one-return pipe of the boiler barrel, and returns to the back by the two-return pipe, and then enters the dust collector to separate the ashes, and then is discharged by the chimney through the induced draft fan.
The induced draft fan is not only necessary for discharging the flue gas, but also for the negative pressure operation of the boiler. A steam boiler is a force vessel, and safety devices are necessary. Biomass steam boilers manufacturing heating core part of the separation of water and electricity, will not cause leakage accidents. Resistance wire heating part of the water and electricity does not separate, electric heat pipe soaked in water for a long time, easy to cause electric leakage accident, harm to human health.
This series of biomass boiler is single boiler tube longitudinal layout chain grate boiler, suitable for combustion molding biomass fuel, but also pure coal burning or mixed coal burning and molding biomass fuel. There is a economizer at the tail. The ash and slag can be directly used as farmyard manure, which is a kind of high efficiency, energy saving and environmental protection product. It is equipped with an induced draft fan for mechanical ventilation and a screw slag extruder to realize mechanical slag discharge, complete control and monitoring instruments, and safe and reliable operation of the boiler.
The above is the introduction of the principle and structure of 4ton biomass steam boiler. Due to the constant innovation of the technology, the technical parameters are also constantly updated. The detailed technical parameters of the boiler are mainly based on drawings. Biomass steam boilers manufacturing operation is stable and reliable, rich production experience, strong technical force, worthy of customer trust. When purchasing a boiler, we must take various considerations from the scale, qualification, technology, production process, public praise, after-sales service and other aspects of the boiler manufacturer to do a comprehensive consideration.
