Boiler - Wikipedia

Gas for the main burner is supplied through a pressure control valve, a flow control valve, the electrically operated automatic shut-off valves, and finally the main gas cock. The automatic shut-off valves are arranged in a "double block and bleed" system that ensures no gas can enter the furnace when the boiler …

Dry Flue Gas Losses This account for major heat losses amongst all. If the flue gases leaving the boiler is at a high temperature than the temperature for which it is designed, then most of the heat is getting wasted leading to reduced boiler efficiency .

The Heat Balance and Efficiency of Steam Boilers

Watertube boilers are also capable of high efficiencies and can generate saturated or superheated steam. In fact, the ability of watertube boilers to generate superheated steam makes these boilers particularly attractive in applications that require dry, high-pressure, high energy steam, including steam turbine power generation.

Difference Between LPG and Natural Gas - LPG vs Natural

a cylindrical vessel mounted at a high point of a water-tube boiler, where dry steam may separate above the water level, so that it may be drawn off without risk of priming. This is similar to the function of a dome in a fire-tube boiler.

Boiler System Energy Losses - Natural Resources Canada

Dry flue gas loss (LDG) Heat is lost in the "dry" products of combustion, which carry only sensible heat since no change of state was involved. These products are carbondioxide (CO 2 ), carbon monoxide (CO), oxygen(O 2 ), nitrogen (N 2 ) and sulphur dioxide (SO 2 ).Concentrations of SO 2 and CO are normally in the parts-per-million (ppm) range
