The water tube boiler adopts the lower support method and can freely expand upwards. D type watertube boiler has compact structure, small footprint and good flame fullness. The furnace water wall and convection flue all adopt membrane wall structure, which has good sealing and effectively reduces the use and maintenance workload of refractory bricks.

The water-tube boiler feed water is pumped to the economizer, and then sent to the steam drum after absorbing the heat of the tail flue gas. The water in the upper steam drum is circulated to the lower drum through the descending convection pipe. Then through the membrane wall in the front of the furnace, the membrane wall in the rear of the furnace, the membrane wall in the furnace, the membrane wall at the side of the furnace, the membrane wall at the side of the furnace, the membrane wall at the side of the convection, and the convection tube bundle to absorb the heat of the flame radiation and the high temperature flue gas in the furnace. A soda-water mixture is formed to reflux upwards to the upper steam drum. The steam-water separator in the steam drum separates the water and steam, and the water returns to the water space in the lower part of the steam drum. Saturated steam passes through the main steam valve and pipeline to steam users.

This series of boiler products is equipped with a condenser at the tail of the economizer. The condenser is designed for atmospheric pressure (use under pressure is strictly prohibited). A circulating pump is used to drive the low-temperature softened water to circulate in the condenser tube, thereby further reducing the exhaust gas temperature of the boiler and improving the thermal efficiency of the boiler. D type watertube boiler adopts high thermal resistance material as thermal insulation layer, which has good thermal insulation performance. The boiler adopts a quick installation structure, which can effectively shorten the installation time.

SZS series boilers realize the advantages of full combustion, no pollution, convenient operation and convenient installation. The boiler has high thermal efficiency, large output, strong load adaptability, high degree of automation, convenient operation, safe and reliable operation. It is an ideal green product with high efficiency, low consumption and low pollution. Water tube boilers are widely used in hospitals, schools, textile factories, garment factories, large supermarkets, garment factories, printing and dyeing factories, hotels, canteens, restaurants, food factories, beverage factories, soy products factories, meat products factories, cannery, wine Factory, pharmaceutical factory, packaging factory, building material factory, paint factory, swimming pool and other enterprises and institutions.

The combustion chamber of the SZS series steam boiler adopts a fully corrugated furnace structure, which not only strengthens the disturbance of the flue gas, but also increases the radiation heat transfer area; it not only increases the rigidity of the furnace, but also effectively reduces the expansion stress of the furnace; both The heat transfer effect is enhanced, and the combustion of the fuel in the furnace is promoted. D type watertube boiler symmetrically hinged front and rear smoke doors: easy to open, easy to repair and clean. When in use, the fuel is burned at a slight positive pressure in the furnace, and the high-temperature flue gas turns 180° backwards along the furnace and enters the first flue tube bundle through the return combustion chamber, and then turns 180° through the compression front smoke box to enter the second tube bundle. After convection heat exchange, it is discharged into the atmosphere. Zozen Boilers specializes in the production of various types of boilers, welcome everyone to come to consult and purchase!
