New type DZH Series coal fired steam boiler is single drum longitudinal type water and fire tube steam boiler,the combustion equipment is moving grate.The boiler mainframe in general configuration adopts the form of drum overhead and bilateral symmetry of water wall tube and header.The drum is installed and welded by boiler barrel and front & back tube plates.It has high burning efficiency due to the spark retaining wall located in the interior of furnace.
This series of boiler adopts latest scientific research achievements,such as arched tube plate, thread smokestacks, etc. It solves the problem of the pot shell type boiler tube plate cracking, pan cone lower speed bulge, water-cooled wall tube explosion, low thermal efficiency, insufficient of power and poor adaptability of coal.
This DZH series coal fired steam boiler is ideal for heating, textile plant, rice mill, garment factory, utility or power plant, hospital, hotel, food & beverage factory, dairy plant, school, chemical industry and more applications.
1. It uses arched tube plate and thread smokestacks constituted into the drum, reduces the stress.The fire tube inside of tube plate is single return instead of two-return, solves the problem of tube plate cracking.
2. The ascendable pipes are arranged at the bottom of drum,this makes the sludge deposit uneasy, prevents the drum bottom swelling.
3. It adopts efficient heat transfer threaded pipes, strengthen heat transfer, and then heating-up and pressure boost -up quickly, the thermal efficiency increased.
4. Compact structure, saving the boiler foundation cost.
5. Stable running, easy to adjust, strong steam output.
6. The smoke tube is not easy for ash deposition, due to the smoke can be disturbed and cleaned by itself.
7. Both wing wall and outlet widow inside of the furnace have the function of dust suppression, thus ensuring the soot discharge scratch the index stipulated by the State Environmental Protection.
