makeup water up to the temperature of the unrecovered condensate. It takes 1 BTU to raise 1 pound of water by 1° F. To determine how many BTU s are required to heat 1 pound of makeup water to the condensate temperature, simply subtract the makeup temperature from the condensate temperature.
Boiler Feed Water Temperature Boiler Feed Water Temperature Vs. kW Required per Pound of Steam The temperature of boiler feed water directly affects the steam output of a boiler. The following table can be used to determine the kilowatt rating of a boiler when the steam load, gauge pressure and boiler feed water temperature are known.
180 litres of water is near enough 180kg. The specific heat capacity of water is approx J / The increase in temperature is 45 Kelvin (6015) So the energy needed is 180,000 x 45 x = 34MJ 1kWh = 1000W x 3600s = Hence,...
If 1 t/h of steam is supplied to equipment for a heating process, then the same amount of condensate (1 t/h) needs to be discharged from the equipment. Condensate recovery is a process to reuse the water and sensible heat contained in the discharged condensate.
Steam driven units require about 9 to 10 pph per ton of 114 psig input steam at ARI standard rating conditions. Gasfired units require an input of about 10,000 to 12,000 BTUH HHV per ton of cooling at ARI standard rating conditions.
The absorption cycle uses water as the refrigerant and heat as the energy input to create chilled water for comfort or process applications. In the absorption cycle, steam or hot water is used to boil a dilute solution of lithium bromide and water in a hermetic vessel. The water vapor produced is drawn through the condenser, where it gives up ...
Electricity generation. Thus, a 1000 MW power plant would use 3,470 to 3,930 metric tons (tonnes) of steam per hour and the steam used by the 1,170,000 MW of worldwide power generation by coalfired and nuclear power plants might be as much as 4,000,000 to 4,600,000 metric tons of steam per hour.

A Btu, or British thermal unit, is the amount of energy needed to raise one pound of water from 60°F to 61°F at sea level. A gallon of water weighs lbs. If the incoming water is 60°F and we want to raise it to 140°F, that is a 80°F rise. Heating a gallon of water thus requires x .
A ton is a measure of weight, whereas a cubic meter is a measure of volume, so the material must be known to be able to convert the units. One ton of pure water is equal to 1 cubic meter. There are 1,000 liters in 1 cubic meter of pure water, and a liter of pure water weighs 1 kilogram. Therefore, 1 ton of water equals 1 cubic meter.
The typical range of net electrical energy that can be produced is about 500 to 600 kWh of electricity per ton of waste incinerated. Thus, the incineration of about 2,200 tons per day of waste will produce about 1200 MWh of electrical energy.

Example — A process requires 450 lbs of steam per hour at 75 psig. The available feed water temperature is 50°F. From the chart, read the kW/lb required for 50°F water and a gauge pressure of 75 psig. Multiply the factor by the pounds of steam: x 450 lbs = kW.
steam system (86%94% utilization), the fuel cost accounts for 96% of the total lifecycle cost while investment, operating and maintenance costs usually account for 3% and 1%, respectively. The cost structure clearly demonstrates that the
It depends on the enthalpy of the steam, pressure of the steam and the degree of superheat and/or reheat added. A ton/hour of steam at 900 psig and 375C will generate less MW than the same ton/hour at 2850 psig and 590C. Also depends on the generator efficiency which is .
