The biomass boiler should choose the boiler lining according to the combustion materials. If it is biomass particles, the temperature in the furnace can reach about 1200 degrees, and coking will occur. The working conditions are very bad. High-quality refractory materials should be selected. If the material is logs, the impact is not significant.
The selection of refractory materials for biomass boilers needs to consider the following aspects:
High-temperature resistance performance: The working temperature of the biomass boiler is relatively high, so it is necessary to choose refractory materials that can withstand high temperatures, and generally require the ability to withstand high temperatures above 1000°C.
Abrasion resistance: When a biomass boiler burns biomass, it may contain particulate matter, which will cause wear to the refractory material. Therefore, it is necessary to choose refractory materials with better wear resistance.
Corrosion resistance: The gas produced by the combustion of biomass boilers may contain some corrosive chemicals, which will cause corrosion to refractory materials. Therefore, it is necessary to choose refractory materials with better corrosion resistance.
Stability performance: choose a refractory material with better stability performance to ensure that its long-term use will not cause problems due to its own chemical changes.
Cost factors: The selection of refractory materials also need to consider cost factors, including the price of the material itself, the cost of installation and maintenance, etc.
In short, the selection of refractory materials suitable for biomass boilers needs to comprehensively consider the above aspects, and select materials with stable performance, reasonable price, and wide application range.
