Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain.Get Price
Typical boiler efficiencies range from about 90% for the best solid biomass fuel boilers to close to 95% for oil- and natural gas-fired boilers, Table 3.2. The main reason for the poorer performance of biofuels is the high moisture content of the fuel, which increases flue gas losses.Get Price
Steam Rankine cycle is known as one of the main power-generating cycles, which consists of four key devices, namely a boiler (heat exchanger), a steam turbine, a condenser (heat exchanger), and a pump, as illustrated in Fig. 28.This cycle needs heat input for the boiler either by burning fossil fuels, such as oil, coal, and natural gas, or by obtaining the necessary heat from renewable …Get Price
The HRT boiler has the capability to use gas, wood, oil, or coal fuels. In this boiler, the flue gases flow from the firebox to the rear of the boiler. 5) Lancashire Boiler. This type of fire tube boiler has the same operation as Cornish boiler, but it has two large flues that contain fires. In 1884, William Fairbairn designed the Lancashire Get Price

Hot water heating boiler. A boiler in which no steam is generated, from which hot water is circulated for heating purposes and then returned to the boiler, and that operates at water pressures not exceeding 160 pounds per square inch gauge (psig) (1100 kPa gauge) and at water temperatures not exceeding 250°F (121°C) at or near the boiler outlet. Hot water supply boiler.Get Price
Oct 05, 2010 · The main difference between nuclear reactor types is that pressurized water reactors keep the boiler water separate from the reactor, which allows this water to be kept free of radioactivity. Nuclear cooling systems are designed so that if pipes begin to leak, local water runs into the plant rather than radioactive water leaking out.Get Price

Dec 17, 2017 · A gas fired thermal power plant uses two types of hydrocarbon fuel with the following molal (volumetric analysis) CH4 = 68% ; C2H6 = 32%. Fuel and air is supplied to the boiler at 101 KPa and 25 C with 30% excess air requirement for complete combustion. Product temperature and pressure are 1000 C and 101 KPa, respectively.Get Price
The blowdown from the flash tank is passed through an exchanger and used to preheat boiler makeup water. With the use of an efficient heat exchange unit, the only heat loss is the terminal temperature difference between the incoming makeup water and the blowdown water to the sewer. This difference usually amounts to 10-20°F (5-10°C).Get Price
