4 Pass Design Johnston maximizes boiler performance design to minimize operations maintenance. 3500-4500 2600' • For many years, there were two choices — a 4 pass dry backed boiler or a 3 pass water backed boiler. This was a hard decision for many users.
Steam Production When heat is added to water, its temperature rises at a rate of 0.56 C (1 F) for each heat input of 2.095 kJ/kg (1 Btu/lb) If we take water at 0 C (32 F) and we add 419 kJ/kg (180 Btu/lb) then we will increase the temperature of the water by 100 C

The vent or stack design for a boiler is supposed to provide the draft required by the boiler/ burner manufacturer. This is usually around 0.05" to 0.5" (inches of water column) of negative or positive draft. Most applications with short stacks have no problems

Draft (boiler) The difference between atmospheric pressure and the pressure existing in the furnace or flue gas passage of a boiler is termed as draft. Draft can also be referred to as the difference in pressure in the combustion chamber area which results in the motion of the flue gases and the air flow.
An 80% efficient boiler generates 45,000 pounds per hour (lb/hr) of 150-pounds-per-square-inch-gauge (psig) steam by burning natural gas. Condensate is returned to the boiler and mixed with makeup water to yield 117 F feedwater. The stack temperature is

2016/2/17 · Oxygen. The air we breathe and use for burner combustion contains about 78% nitrogen, 21% oxygen, and about 1% argon and trace elements of other gases. It is adjusted to the least amount possible for best efficiency. If the burner has too much air or insufficient fuel, it is called lean and lowers the efficiency.
