Introduction:
SZL series water tube  hot water boiler is designed by our engineer that learn the advanced technology at home and abroad and experience, which is the horizontal type double drum Longitudinal type chain grate water tube steam boiler and hot water boiler .This series boiler has reached the international advanced level at technology, performance, environment protection.

Application:
This series hot water boiler is widely used in industry and life which need steam, the relevant capacity hot water boiler is widely used in industry and heating for civil use. It is also ideal for heating, textile plant, rice mill, garment factory, utility or power plant, hospital, hotel, etc.

Technical Advantages:
1. Furnace arch adopts advanced design, forming obvious inverse “α” flue gas flow, which make the boiler have 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.
