The coal burner's installation.

We have two principles. First, there is enough distance among the burners. and

flow air can be freely expanded and form recirculation zone in order not to interfere one

another. Second, the flame cannot swash against the adjacent wall or block wall , which

will lead to slagging in the adjacent wall or block wall. With regard to industry boiler, the

basic layout form has four styles :

1. Quadrangular layout.

2 Relative collision layout front wall against back wall.

3.Front wall layout.

4.Layout at the top of the boiler.
