Background

Coal is a main industrial production in Vietnam and is widely used as fuel in many indusrties. A set of steam boiler is needed for TAN PATH EQUIPMENTJ.S.C to sypply large quantity of steam in production process. The 4 ton chain grate boiler they have purchased was a three pass, fire-water tube boiler with rated steam pressure 1.25MPa. The packaged chain grate boiler was designed to burn bituminous coal as fuel and its thermal efficiency can reach 79%.
