Boiler (power generation) - Wikipedia

Boiler (power generation) 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 (72,000 kPa or 1290 psi) but, at pressures above this, it is more usual to speak of a steam generator .

Flame Characteristics of Oxy-fuel Combustion and Burner

8.1. Introduction. Oxy-fuel flame characteristics in ignition, flame stability, flame shape, etc. are different from those in conventional air combustion because of the changes in the oxidants composition, which mainly consists of CO 2, H 2 O, and O 2.Compared to a constant initial oxygen concentration in air combustion, the initial oxygen concentration can be controlled by the flue gas Cited by: 1Publish Year: 2018Author: Junjun Guo, Zhaohui LiuHigh Pressure Boilers: Features and Advantages ~ ME Mechanicalhttps://me-mechanicalengineering.com/high-pressure-boilersOct 27, 2016· A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.

Scotch marine boiler - Wikipedia

Scotch marine boiler. The Scotch boiler is a fire-tube boiler, in that hot flue gases pass through tubes set within a tank of water. As such, it is a descendant of the earlier Lancashire boiler, and like the Lancashire it uses multiple separate furnaces to give greater heating area for a given furnace capacity.

Understanding Steam & Boiler Heating Systems | HomeAdvisor

Boiler Systems Operation. In steam heating systems, a boiler furnace heats water by means of a gas or oil-fired burner and turns it into steam. The steam travels through pipes to radiators or convectors, which give off heat and warm the room. As the steam cools, it condenses back into water, and returns to the boiler to be heated again.
