Why does the biomass boiler do not need water for a period of time from ignition?

　　Biomass boilers have some common problems, as well as some difficult problems, such as: Why does the boiler need no water for a period of time from ignition? If it uses a cast iron economizer, how to solve the cooling problem during the ignition process? Now that these questions have been raised, let's give the correct answers below so that everyone can have a complete and correct understanding.

　　1. Why is there no need for water for a period of time after the ignition of the biomass boiler?

　　In this case, according to technical personnel, after the ignition of the citation boiler, the volume of the boiler water increases due to the increase in the temperature of the boiler water, which in turn causes the water level to rise. As the temperature of the boiler water further rises, water vapor is generated in the water wall and the boiler water level further rises. Therefore, it does not need water during this period of time from the start of ignition.

　　2. If the biomass boiler uses a cast iron economizer, how to solve the cooling problem during the ignition process?

　　If the economizer in the furnace is a cast iron economizer, then, because this economizer is not resistant to water hammer, it is not allowed to generate steam. Therefore, it cannot be set again. The circulation pipe is used to solve the cooling problem during the ignition process, but the bypass flue is set to solve the cooling problem of the economizer during the ignition process.
