A valve is required to open at 500 psig inservice where the service temperature is 400° F, and back pressure = 25 psig. Differential set pressure = 500 psig – 25 psig = 475 psig. Temperature multiplier: 1.013. Cold differential test pressure = 475 psig x 1.013 = 481 psig. This valve would have a stamped set pressure of 500 psig and a CDTP of

Boiler feed pumps operate at fluid temperatures of 160 to 210 ºC. In exceptional cases the temperature of the fluid handled may be higher still. Feed pumps for 1600 MW nuclear power stations are constructed for mass flow rates of up to 4000 tonnes/h and feed pump discharge pressures of 70 to 100 bar.

10.2.1 Kettle reboilers. A kettle reboiler (Figure 10.1) consists of a horizontally mounted TEMA K-shell and a tube bundle comprised of either U-tubes or straight tubes (regular or finned) with a pull-through (type T) floating head. The tube bundle is unbaffled, so support plates are provided for tube support.

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 the plant, and is simply on stand-by.

Cochran Boiler is a multi-tubular vertical fire tube boiler having a number of horizontal fire tubes. It is the modification of a simple vertical boiler where the heating surface has been increased by means of a number of fire tubes. The efficiency of this boiler is much better than the simple vertical boiler.
