18. Q. How would you start and operate stoker?

A. First open main valve No. 1 at steam turret. Valve 2 is then opened;

this is the main valve in stoker steam line. Next open valve 3, which

allows the steam to flow to the distributor jet line; open valves 4 and

5, which govern the pressure on the jets until ten pound pressure shows

on the right-hand gauge. See valve 8 to the exhaust line is open, and

valve 9 to the transfer hopper is closed.
