From Example 8.2, the existing boiler has an excess O 2 of 6% and an overall boiler thermal efficiency of about 78% (i.e., η s t d = 0.78). After the boiler tune-up, the excess O 2 is 3%. Using the monograph of Fig. 8.12, the new boiler efficiency can be determined from the flue gas temperature (343°C or 650°F) and the excess O 2 (3%).Get Price
3.4.1 The CHP plant. CHP plants producing heat and power are usually based on a Rankine cycle with steam superheating. The steam from the boiler is superheated, at the constant pressure, to a higher temperature than the saturation point. A flow sheet example of this process is presented in Figure 3.6 (Sipilä et al., 2005). If the process is Get Price
Aug 31, 2018 · Boiler feed pump must not only be able to supply feed water requirement; but also work as a condensate and makeup water pump when required. To ensure proper operation of these pump; feed water must be free from steam, air and insoluble solids. Parts of Boiler Feed Pump The image display a high capacity boiler feed pump used in thermal power plant.Get Price
Jun 08, 2018 · Boiler types : According to usage • Hot water boiler • Thermal oil boiler • Steam boiler • Steam generator • Exhaust gas boiler 20. Hot water boiler: Hot water boilers are normally used in room and building heating. These kinds of systems are suitable for discharge temperatures of up to 140°C.Get Price
Dec 25, 2021 · An auxiliary motor shall also be provided for inching of mills after trip and during maintenance. ii. In a steam boiler, the water is heated up by burning the coal in the air in the furnace and the function of the boiler is to give dry superheated steam at the required temperature. In the thermal power plant coal is burnt to generate Get Price
Jan 01, 2013 · • Facility's heat-to-power ratio: If the heat-to-power ratio in the facility is higher than that for the cogeneration plant, the excess steam demand is usually met by utility boilers. Any saving in steam demand (by better heat recovery) saves fuel in the utility boilers and leaves the operation of the cogeneration plant unchanged.Get Price

The boiler mountings are generally mounted over the boiler shell. They ensure the safe function of the steam boiler by controlling the fluid parameters inside the boiler shell. Without them, a boiler cannot function safely. There are mainly 7 mountings required to operate a boiler. We will discuss the function and working of each of them.Get Price

Examples of this type of failure include cracks in boiler components at support brackets or rolled in tubes when a boiler undergoes thermal fatigue due to repeated start-ups and shutdowns. Thermal fatigue occurs in horizontal tube runs as a result of steam blanketing and in water wall tubes due to frequent, prolonged lower header blowdown.Get Price
