DZL seires coal/biomass fired steam boiler realizes almost zero pollution with the use of special dust collector solution (bag dust collector, double towers desulfurization, etc.). This series boiler is single drum horizontal type shell boiler, the combustion equipment is chain grate (small scale flaker is available), has the advantages of feed mechanically and strong adaptability of different fuels. The fuel could be II class bituminous coal, the diameter should be 6-25mm, and ash content should be less than 32.4%. Otherwise, DZL series boiler could also burn biomass fuel, including wood, straw, bagasse, rice husk, coconut shell, cotton seeds, peanut shell, etc.

Performance Features

1. The biomass steam boiler is a horizontal fast-loading steam boiler with natural circulation of working medium.The heat exchange system of the steam boiler is composed of the boiler barrel, the left and right sets, and the water cooling wall. The main heating surface has the water cooling wall of the furnace, part of the boiler barrel and the convection tube bundle inside the boiler barrel.This series of steam boiler is composed of five parts: boiler body, smoke duct, dust collector and pipeline system.The first four parts have been manufactured in the factory and transported to the installation site for assembly, which can greatly shorten the installation cycle and ensure the installation quality of products.

2. Excellent boiler design performance: the main heating surface tube of the steam boiler is made of seamless steel tube of no. 20 low and medium pressure boiler, and the boiler barrel is made of special steel plate for the boiler.The left and right containers are made of seamless steel tubes.

3. The coal fired steam boiler arch is made of fire-resistant concrete.The rear arch is low and long, so it burns well. The wings of the flue and the side wall tiles are made of refractory sintered bricks.Boiler front wall and back wall adopt universal firebrick.

4. Reasonable blast distribution of boiler grate, large combustion chamber and strong applicability of coal.Suitable for all kinds of bituminous coal or anthracite, mixed coal.Full combustion. As the high-temperature smoke enters the settling chamber and then enters the two wings of smoke flue and front smoke box from both sides, the effect of smoke elimination and dust removal is good.

5. Simple water circulation, reasonable structure of pressure components, under the condition of ensuring water quality, completely safe operation.

6. The steam boiler combustion equipment is a fast-loading grate, which can be manufactured and installed in the factory and directly installed on the foundation after being transported to the site.With reasonable structure, compact, low steel consumption, so that the boiler performance, weight, structure and size compared with domestic boilers with the same capacity has obvious advantages.
