Sawdust as fuel - woodweb.com

The boiler was made in 1917 and is still in good repair. Trash grates are sometimes called "step grates" as they are primarily set up like stair treads at about 30 degrees of slope. At the bottom of the step grate is a smaller vertically barred grate. Other than a good natural draft created by a 60 - 70 foot chimney, nothing else is needed.

Combustion Source Inspection: Student Reference

For good combustion, air flow must vary along the bed. This can be accomplished in several ways. In a typical chain-grate installation, for example, the space between the upper and lower strands of grate forms a common air chamber, which allows equalization of air pressure under the entire grate.

When this type valve is in the open position, steam can flow from the boiler but cannot return. This prevents the possibility of steam entering the boiler through the main steam line from another boiler when it is idle. It is very important that care be exercised when opening a main stop valve or any other stop valve on a boiler.
