  • Water for the Boiler

    Water for the Boiler. The operating objectives for steam boiler plant include: Safe operation. Maximum combustion and heat transfer efficiency. Minimum maintenance. Long working life. The quality of the water used to produce the steam in the boiler will have a profound effect on meeting these objectives.

  • Boiler Efficiency and Combustion

    A reasonably well-insulated shell or water-tube boiler of 5 MW or more will lose between 0.3 and 0.5% of its energy to the surroundings. This may not appear to be a large amount, but it must be remembered that this is 0.3 to 0.5% of the boiler's full-load rating, and this loss will remain constant, even if the boiler is not exporting steam to ...

  • Condensate Recovery

    Typical application s for flash steam. Flash steam supply and demand in-step. This gives maximum utilisation of the available flash steam. The air heater battery discussed in Figure 14.6.5 is one such system, but similar arrangements are practical with many other applications such as space heating installations using either radiant panels, or unit heaters.

  • Pressure Control Applications

    There are many good reasons for reducing (and sometimes maintaining) steam pressure. Find out about the common applications for direct operating, pilot operated, pneumatic, electric and electropneumatic pressure control systems, including the advantages and disadvantages of each different control method.

    Heat Recovery from Boiler Blowdown TDS Control Only. Boiler water is blown down to control the amount of total dissolved solids (TDS) in the boiler. This water is pressurised, hot and dirty, creating large volumes of flash steam and possible disposal problems. A heat recovery system can reclaim large amounts of energy during this essential process.

  • Steam Consumption of Heat Exchangers

    A shell and tube heat exchanger used to heat water for space heating (using either steam or water) is often referred to as a non-storage calorifier. (A storage calorifier, as shown in Figure 2.13.1, is constructed differently, it usually consists of a hot water storage vessel with a primary heating coil inside).

  • Pressurised Deaerators

    The operating pressure will usually be approximately 0.2 bar (3 psi), which gives a saturation temperature of 105°C (221°F). The vessel will contain between 10 and 20 minutes water storage for the boiler on full-load. The water supply pressure to the deaerator should …

  • Introduction to the boiler house

    This meant that less energy had to be stored in the boiler water. The boiler could therefore be smaller, radiating less heat to the environment, with a consequent improvement in efficiency. The smaller size also meant that the boiler occupied less production space. Mechanical stokers were eliminated, reducing maintenance workload.
