  • Sulfites for Oxygen Control - Scranton Associates

    For lower erythorbate content, the same sequestering process releases it from solution as it is diluted and as alkalinity increases in the boiler. This allows any free erythorbate present to catalyze the sulfite/oxygen reaction and validates it as a safe, non-metallic agent of catalysis.

    pressure the average pressure cooker operates on but lets say, for the sake of argument, that it makes steam at 15 pounds per square inch. At that pressure something else happens--our pound of water does not boil at 2120F, it boils at 250°F, and the temperature of the steam is now 250°F. Inside the pressure cooker, just as in the open pan of

  • Flue-gas stack - Wikipedia

    A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler

    Jun 12, 2017 · High Pressure, High Temperature Boilers for utility power applications have experienced steady increases in operating pressures from 1200 psi to 5500 psi. Superheated steam temperatures have increased from 700 o F to 1200 o F. Boiler capacities have increased from around 140,000 pounds of steam per hour to about 3,000,000 pounds of steam per hour.

    Steam pressure reduction affects mainly the high pressure part of the steam system. Within practical limits, pressure-reducing valves (PRVs) will adjust the pressure at lower levels to the previous set points. This means that most of the savings benefits from pressure reduction occurs in the high pressure section of the steam system. Summary. 1.

  • Fire-tube boiler - Wikipedia

    A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank
