FANGKUAI’s H6 series oil fired hot water boiler is a fully condensing hot water boiler. The combustion system adopts advanced full premixed burners to increase the heat load of the furnace volume and reduce the generation of high-temperature NOx; large space natural convection and forced convection to ensure the heating surface. Uniform flushing reduces the requirements for boiler water quality and greatly improves boiler efficiency. The oil hot water boiler with an overall layout based on rigorous thermal expalma pipe networks saves capital investment costs. This type of furnace is very suitable for low-temperature heating systems such as hotels, schools, baths, and other enterprises and institutions that provide heating and domestic hot water.
