Boiler Efficiency and Combustion | Spirax Sarco

Pressure jet burners. A pressure jet burner is simply an orifice at the end of a pressurised tube. Typically the fuel oil pressure is in the range 7 to 15 bar. In the operating range, the substantial pressure drop created over the orifice when the fuel is discharged into the furnace results in atomisation of the fuel.

It controls the flow of water from the feed pump to the boiler and prevents return flow from the boiler to the feed pump. The return flow occurs when the boiler pressure is more than the pressure of the feed pump. Fusible Plug. Function: The function of a fusible plug is to extinguish the fire in the furnace when the water level drops very low.

Another consideration is whether the exhaust stack will be under a positive or negative pressure. This can determine how the joints of the exhaust stack must be sealed. Boiler controls help produce hot water or steam in a regulated, efficient, and safe manner. Combustion and operating controls regulate the rate of fuel use to meet the demand.

Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
