Boiler Efficiency - an overview | ScienceDirect Topics

Circulating cooling water leaving the condenser is utilized to preheat the air used for drying the coal. The temperature of the circulating water leaving the condenser is usually about 49 °C and can be used to produce an air stream at approximately 43 °C, which is fed into a fluidized-bed coal dryer. Approximately a quarter of coal moisture

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.

Three-drum boiler - Wikipedia

The Yarrow boiler design is characterised by its use of straight water-tubes, without downcomers. Circulation, both upwards and downwards, occurs within this same tube bank. Alfred Yarrow developed his boiler as a response to other water-tube designs, and his perception in 1877 that Yarrow & Co were lagging behind other shipbuilders. His initial thoughts already defined the key features of the

Expansion tanks: how to diagnose & bleed a waterlogged hot

In older hot water heating boiler expansion tanks that do not have an internal bladder to keep air and water separate, over time air in the expansion tank may become absorbed into the heating water. Air may also find its way via the heating water to other air bleeders or vents in the system.

Inhibition of lignite ash slagging and fouling upon the

Jan 01, 2015 · Most coal fired boilers are equipped with soot blowers that use a high-pressure jet of superheated steam, saturated steam, water or compressed air to remove ash deposits . However, the soot blowing is energy-intensive, and hence, its utilisation negates the overall efficiency of a boiler and causes erosion and damage to water tubes as well

What Size Heat Pump Do I Need? | Boiler Guide

If your home is currently heated by a boiler then an air-to-water heat pump is likely to be the better option. This is because they heat water before circulating it around a wet central heating system such as radiators or underfloor heating. It's worth noting that air-to-water heat pumps can't heat water to the same high temperature as boilers
