Due to combustion chamber applying whole membrane water cooling structure and micro-positive pressure combustion, there is no smoke leakage and no pollution to the environment.2. With anti-explosion door and flame detector, the boiler is safer and reliable.3. The water circulation is enforced. That can ensure every heating area can be cooled and no vaporization happens.4. We adopt spiral finned tube economizer. That can reduce the smoke temperature and increase the heat efficiency up to 92%.5. Compact structure. It covers small space in the boiler house.6. The manholes are designed at each end of the double drums, and the check door is designed at the back of boiler. The door is easy to open and is very convenient to do maintenance and cleaning job.7. The boiler is assembled for delivery. It is easy to transport and installed at site.8. The boiler achieves full automation control. It is easy to operate.Steam capacity scope: 2T, 4T, 6T, 10T, 15T, 20T, 25T, 30T, 35T, 50THot water capacity scope:7MW, 10.5MW, 14MW, 17.5MW, 21MW, 29WM, 46MW, 58MW, 70MW, 116MW. ModelRated thermal power(MW)Rated working pressure(MPa)Rated output water temperature(ºC)Rated Feeding water temperature(ºC)SZS7-1.0/115/70-Q7111570SZS10.5-1.0/115/70-Q10.5111570SZS14-1.25/115/70-Q141.2511570SZS17.5-1.25/115/70-Q17.51.2511570SZS21-1.25/130/70-Q211.2513070SZS29-1.25/130/70-Q291.2513070SZS46-1.6/130/70-Q461.613070SZS58-1.6/130/70-Q581.613070SZS70-1.6/130/70-Q701.613070SZS116-1.6/130/70-Q1161.613070From Zozen and Shinmo Team, we have more than 15 years of experience in manufacturing and exporting.
