8. Q. How is the distribution of coal over the grate area accomplished?
A. By means of a low-pressure constant steam jet located in the back and bottom portion of each distributor elbow, as indicated by its individual pointer on steam gauge.
9. Q. By increasing the jet pressure, will more coal be carried to forward end of fire-box and against the flue-sheet?
A. Yes, it will, and by decreasing the jet pressure more coal will be fed at middle and back end of fire-box.
10. Q. Can the fireman direct the even distribution of coal in the fire-box?
A. Yes; by changing position of the dividing rib located in the transfer hopper, and by moving the regulating lever to either side.
11. Q. Should the sliding plates at the bottom of the tank be closed before coal is put on tank?
