Boiler feedwater heaters are designed to improve boiler efficiency by extracting heat from streams such as boiler water blowdown and turbine extraction or excess exhaust steam. Feedwater heaters are generally classified as low-pressure (ahead of the deaerator), high-pressure (after the deaerator), or deaerating heaters.Get Price
An air-to-water heat pump is the most common model in the UK and works by absorbing heat from the air outside and transfers the heat to water. This type of heating system distributes through your wet central heating system and work more efficiently at lower temperatures than a standard boiler system.Get Price
Aug 19, 2019 · In the same way, a fuel source is burned in the furnace, causing the water tubes inside to heat up. Once again, when the water is boiled, steam is generated and moved downstream. A water-tube boiler is more thermally efficient than a fire-tube boiler, but they are more complex to construct and the quality of the water can be a limiting factor.Get Price
