For all of those reasons a spare nozzle is a desirable item for a service- man to carry. b. FLAME SHAPE — Looking into the combus- tion chamber through the flame plug hole, the flame should appear straight with no sparklers rolling up toward the top of the chamber.
- Page 21 It chills the flame, causes smoke, and allows unburned fuel to pass through the combustion chamber and clog the flueways of the boiler. h. COLD OIL— If the oil temperature approaching the fuel pump is 40°F or lower, poor combustion or delayed ignition may result.
- Page 22 A leaky system will increase the volume of make-up water supplied to the boiler which can significantly shorten the life of the boiler. Entrained in make-up water are dissolved minerals and oxygen. When the fresh, cool make-up water is heated in the boiler the minerals fall out as sediment and the oxygen escapes as a gas.
