Energy Content in Some Common Energy Sources

The unit of heat in the imperial system - the BTU - is. the amount of heat required to raise the temperature of one pound of water through 1 o F (58.5 o F - 59.5 o F) at sea level (30 inches of mercury). 1 Btu (British thermal unit) = 1055.06 J = 107.6 kpm = 2.931 10-4 kWh = 0.252 kcal = 778.16 ft lb f = 1.05510 10 ergs = 252 cal = 0.293 watt hours

Flue Gas - an overview | ScienceDirect Topics

Flue gases containing CO 2 are flowed through the absorber countercurrent to the flow direction of absorbent solution. Inside absorber tower, the absorbent solution reacts chemically with the carbon dioxide in the flue gases. The treated gases are vented to the atmosphere and CO 2-rich solution leaves the bottom stage of absorber.The CO 2-rich solution is entered into regeneration tower and is

residual oil, and refinery off gases are available. Applications include : conventional power generating stations and consists of a heat source (boiler) that converts water to high pressure steam. In the steam cycle, water is first pumped to elevated pressure, which is medium to In the simple schematic shown, a fuel boiler produces

Vapor-compression refrigeration - Wikipedia

Vapor-compression uses a circulating liquid refrigerant as the medium which absorbs and removes heat from the space to be cooled and subsequently rejects that heat elsewhere. Figure 1 depicts a typical, single-stage vapor-compression system. All such systems have four components: a compressor, a condenser, a metering device or thermal expansion valve (also called a throttle valve), and an

Rankine Cycle - an overview | ScienceDirect Topics

Bruce G. Miller, in Clean Coal Engineering Technology, 2011 7.1.1 Rankine Cycle. The Rankine cycle is the basis of all large steam power plants, as briefly discussed in Chapter 6 (refer to Figure 6.16).In coal-fired power plants, high-temperature, high-pressure steam is produced by converting the chemical energy stored in the coal into thermal energy and transferring the energy to the working

Heat exchangers (cooler) Heat exchangers are used to remove heat from the circulating oil in the hydraulic system. The most common heat exchanger is water-to-oil but some times air-to-oil units are used. Coolers will cool the fluid. Heat exchangers (heater) Heaters are used to warm the fluid. Cylinders

Industrial furnace - Wikipedia

An industrial furnace, also known as a direct heater or a direct fired heater, is a device used to provide heat for an industrial process, typically higher than 400 degrees celsius. They are used to provide heat for a process or can serve as reactor which provides heats of reaction. Furnace designs vary as to its function, heating duty, type of fuel and method of introducing combustion air.
