What if biomass-fired boiler furnace wall cracks, deformation, coking, and tilt, loose bricks, tube wall was totally stuck and rock wool sealing is burned out & combustion chamber wall is damaged?
A biomass-fired boiler furnace that has multiple issues such as wall cracks, deformation, coking, and tilt, loose bricks, tube wall blockage, burned-out rock wool sealing, and combustion chamber wall damage requires immediate attention to prevent further damage and potential safety hazards.
Firstly, it is recommended to shut down the boiler immediately to prevent any further damage and ensure the safety of the surrounding area. The boiler should not be restarted until all necessary repairs have been completed.
Secondly, a qualified technician should be called to assess the extent of the damage and provide recommendations for repairs. The technician may conduct an inspection of the entire boiler system to identify any other potential issues that may need to be addressed.
Depending on the severity of the damage, repairs may involve replacing damaged components, such as the combustion chamber or tube walls, and repairing any cracks or deformations on the furnace wall. Loose bricks should be fixed or replaced, and the rock wool insulation should be replaced if it has burned out.
