Boiler body uses the forced circulation in the high temperature area to make sure all heating areas can be cooled down and avoid vaporization; The explosion door and flame detector are equipped for safe and reliable operation. Comb plates are used between both sides of boiler and tube bundle to avoid leakage of condensate and gas caused by using refractory concrete as sealing material. Air proof test is done before delivery in the factory to guarantee any gas leakage problem.

Big combustion chamber equipped with Low emission combustion burner effectively reduce the NOx to 30mg/m3. Smoke duct and smoke outlet use internal insulation to reduce operating noise.Combustion chamber uses full membrane water cooling wall structure and pressurized combustion without smoke mixture.
