For some factories and enterprises that use industrial boilers as heating equipment, they must not only improve the thermal efficiency of the boilers and reduce fuel consumption. But also pay attention to another safety issue, that is, to prevent boiler explosion accidents. Although the biomass boiler manufacturing is one of the environmentally friendly boilers, it also requires constant attention to explosion accidents. After continuous research and testing, Zozen Boilers has summarized some of the reasons for the explosion of the raw biomass boiler.
Reasons for Explosion of Biomass Boiler
- Combustion explosion in the biomass boiler furnace: The main reason for the explosion in the furnace is that the liquid has been staying in the furnace. And the explosion will occur when the concentration of combustibles in the gas reaches a certain level. If the boiler goes down to purge the furnace when it is not started. Or if it is operated according to regulations when it is ignited, a furnace explosion may easily occur.
- The operating pressure exceeds the design pressure: The biomass boiler has a certain rated working pressure when it is designed. When the actual operating pressure exceeds the design pressure, an explosion accident occurs; the pressure gauge fails, and the safety valve does not operate after overpressure. Firefighters are off duty, the monitoring is insufficient, the main steam valve is closed, the safety valve fails. The boiler design N is unreasonable, and the manufacturing quality is poor . The quantity is unqualified, the material does not meet the requirements, the welding quality is poor, there is no regular maintenance inspection, long-term non-maintenance, causing corrosion of the boiler, reducing the pressure-bearing capacity, etc. causing an overpressure explosion.
- Explosion under normal working pressure: The pressure element of the biomass boiler is defective or damaged, and the explosion occurs gradually to a certain extent. Such as corrosion and wear of steel plates, defects in manufacturing, maintenance and welding, poor accumulation of dirt and heat transfer in the boiler, and rapid cooling of equipment caused by illegal water intake when the boiler is short of water, etc. May cause explosion accidents.
Therefore, when the above situation occurs during the operation of biomass boilers, relevant measures need to be taken as soon as possible to avoid accidents caused by explosions. As we all know, biomass boiler is a kind of boiler. Mainly biomass energy as fuel for the boiler called biomass boiler. Biomass boiler manufacturing can be divided into biomass steam boiler, biomass hot water boiler, biomass hot air furnace, biomass heat conduction oil furnace, vertical biomass boiler, horizontal biomass boiler, etc.
Combined with the case of boiler explosion in recent years, we must choose the boiler with high quality and stable operation. Generally, the biomass boiler efficiency of Zozen boiler is above 80%. The biomass boiler manufacturing model is larger and the combustion is more full, so the boiler efficiency is higher. The highest was 88.3 percent, 15 percent more efficient than the average coal-fired boiler. The industrial boilers we produce are of high quality and are widely sold in all countries and regions of the world. They are highly praised and trusted by customers, is a high quality boiler manufacturing enterprises.
