Introduction:
SZL series water tube steam boiler  is designed by our engineer based on the advanced technology in domestic and international, which is the horizontal type double drum longitudinal type chain grate water tube boiler, it contains both steam generator and hot water boiler. This series boiler has reached the international advanced level on technology, performance, environment protection.

industrial horizontal type coal fired water tube steam boiler

Application:

This series steam boiler is widely used in industry and life where need steam and heating, such as textile plant, rice mill, garment factory, utility or power plant, hospital, hotel, etc. The relevant capacity hot water boiler is widely used in industry and heating for civil use.

Technical Advantages:
1. Furnace arch adopts advanced design, forming obvious inverse “α” flue gas flow, which makes the boiler strong adaptability.
2. Boiler’s back and forth arches are water-cooling “warm arch” structure, which can protect furnace arch.
3. Boiler adopts bilateral inlet air and independent plenum structure, can adjust blast capacity and wind pressure of each plenum, to ensure the burning effect.
4. Grate back-shaft adopts roller bearing structure, to avoid sliding bearing over-burning.
5. The bottom road rail of grate adopts light rail, which improve the operation’s reliability.
6. The length of grate is 500-1000mm longer than domestic, which enhance the thermal efficiency.
7. Boiler design adopts light furnace wall structure, which makes the absorbed heating capacity reduce and the boiler starts and stops quickly.
