Boiler Technologies: Submerged Combustion Direct Contact

In a submerged combustion direct contact boiler, water flows downward through a vertical column filled with stainless steel packing rings. Cold water comes into direct contact with the rising hot combustion air from a gas burner. Heat from the combustion gases is transferred to the water and the heated water accumulates in a storage tank. The burner flame does not contact the water directly. Heat transfer is optimized without the use of heat transfer surfaces that can become fouled. The process also produces very low NOx emissions.
