The SZS series steam boiler adopts a double-drum vertical D-type layout design. The pressure of the boiler body is in good condition. Important pressure components such as the drum are not directly radiated and washed by the high-temperature flame. The pressure components of the 20 Tons natural gas boiler can expand and contract freely and heat The stress is small and a high safety margin is achieved.

The natural gas steam boiler is fixed on the chassis of the main body through movable supports in the middle and both ends of the lower drum, and the overall expansion of the boiler to the two ends is ensured. This series of steam boilers are surrounded by membrane water walls, and the membrane water walls on the left side of the furnace completely seal the furnace and the convection tube bundle. The rear part of the convection tube bundle area is a diarrhea staggered structure, and the front part is an in-line structure. The flue gas generated by the furnace combustion enters the combustion chamber and convection tube bundle area from the smoke outlet at the end of the furnace, and then turns from the front of the left side of the boiler into the spiral finned tube economizer and condenser, and finally enters the flue.

Gas steam boilers are widely used in the food industry, chemical industry, packaging industry, pharmaceutical industry, biological equipment industry, washing and ironing, concrete curing, cleaning and other industries. The 20 Tons natural gas boiler is packaged in 304 stainless steel, runs ultra-quiet 80dB, and has an ultra-long operating life of 20 years.

The SZS series natural gas boiler adopts the overall design of the full membrane wall, and the high-temperature flue gas is surrounded by the sealed membrane wall, which overcomes the defect of conventional boilers due to incomplete sealing of the boiler and smoke leakage, and ensures the efficiency and safe operation of the boiler. The equipment is safe and reliable in operation, with sufficient output and high thermal efficiency. It is equipped with a high-intelligence automatic control system, which is convenient to operate.

The 20 Tons natural gas boiler equipment is safe and reliable in operation, with sufficient output and high thermal efficiency. This series of gas-fired boilers use high thermal resistance and light-weight thermal insulation materials, which have a better thermal insulation effect than traditional refractory concrete/refractory brick thermal insulation methods, and at the same time greatly reduce the total weight of the furnace body. Radiant heat transfer insulation measures (heat emission film) are set in the insulation layer to reduce the radiation heat loss that is ignored in the traditional insulation process.
