HFW series of full automatic oil/gas hot water boilers are horizontal internal combustion three return fire tube structure. The corrugated furnace is the first pass, the second pass is made up of the threaded pipes, and the smooth smoke tubes constitute the third pass.The high temperature flue gas scours second and three pass pipes in turn, then it enters into the rear smoke box and is discharged into the atmosphere through the chimney. The large volume combustion chamber adopts the full corrugated furnace structure, increases the heating area and has good disturbance, which strengthens heat transfer and has high thermal efficiency. The combustion equipment adopts high quality and reliable international brand burner to make the fuel completely burn with less harmful pollutants and no noise. The boiler is equipped with complete automatic control device and safety protection device so as to ensure the safe operation.
