Product Details

Company contact:

Tong Hai Power the pioneer industrial boilers of China market, and we have various boilers for worldwide customers.

Product introduction:

1. The structure DZL boiler horizontal fast-assembling fire tube boilers and natural circulation.

2. Advanced design: The main heating tube of the boiler uses 20# low and medium pressure boiler seamless pipe and the boiler drum uses the special steel.

3. The front arch of the boiler use refractory brick. The back arch is low and long, so it has good combustion. Both blank flue and side wall use refractory bricks. Front wall and back wall of the boiler use common refractory bricks.

4. Reasonable air distribution in the grate, large combustion chamber, widely types of coal. The DZL boiler could use bituminous, anthracite or mixed coal. Because of high temperature flue gas enters the settling chamber firstly, and then from both sides of the flue into the wings, front smoke box, so it has good dust abatement.
