Defining Combined Heat and Power (CHP) Steam . Fuel . Electricity . Prime Mover & Generator Heat Recovery Steam Boiler . Conventional CHP (also referred to as Topping Cycled CHP or Direct Fired CHP) • Simultaneous generation of heat and electricity • Fuel is combusted/burned for the purpose of generating heat and electricity
The turbine can either drive a generator (combined cycle system) or just use the steam in process applications (cogeneration or combined heat and power (CHP)). HRSGs can have either a single steam drum (as shown in the animation below) or multiple steam drums and pressures.
In order to get around these problems, the Rankine Cycle uses superheated steam from the boiler to the turbine. The condenser completely condenses the exhaust steam into saturated water. The compressor is replaced with a water (feed) pump to return the water to the boiler. The result of this is reduced efficiency but greater quantities of power
Trigen added a 1.2 MWe gas turbine with a heat recovery steam generator to drive both a 1.2 MWe electric generator and an ammonia screw compressor for the production of chilled water.

Home » Boilers & Power Generation » Steam Turbine Used 15.6 MW condensing steam turbine generator set boiler capacity of 80 t/hour of steam, with The CHP technology based on a steam turbine process thermal capacity of 20-30 MW fluidised tube boilers.
Working principle HRSG is originated and developed from the conventional boiler and heat exchanger. In terms of construction, it can be divided into flue gas type and shell & tube type. The flue gas HRSG is similar to the conventional boiler: the hot fluid in the furnace heats the tube bundle to create high-temperature steam or hot water.
Amherst College's cogeneration system consists of a 1250-kW gas turbine generator that burns natural gas or diesel fuel. The turbine, similar in design to a small aircraft engine, will turn an electrical generator connected to the campus electrical system and send its hot exhaust to a heat recovery steam generator (HRSG).
The captured heat can be used to provide steam or hot water to the facility. Capturing and using the waste heat allows CHP systems to reach fuel efficiencies of 75% or higher, compared to about 50% for the combination of utility-delivered power and an on-site boiler (see Figure 1).

Use boiler horsepower to calculate steam flow. Boiler horsepower is not related to mechanical horsepower. It is a boiler industry rating that predicates the amount of saturated steam a boiler will generate starting with water at 212 degrees Fahrenheit and 0 pounds per square inch gauge (psig--meaning atmospheric pressure) and ending with steam at 212 F and 0 psig.
By nature steam boilers are more complex than hot water boilers. With more variables to contend with, like steam pressure and water quality, it is important to understand the various design options along with their advantages and drawbacks in order to select the best boiler for any given application.
The three smaller boilers are used during maintenance of the larger coal boiler. Steam produced by these boilers, at high pressure (800 psig), is fed into three turbines with a total capacity of 40 MW. Two of these turbines are duel-extraction turbines, which output steam at both medium (400 psig) and low (50 psig) pressure.

Steam turbines are widely used for combined heat and power (CHP) applications in the United States and Europe. Unlike gas turbine and reciprocating engine CHP systems, where heat is a byproduct of power generation, steam turbine generators normally generate elec tricity as a byproduct of heat (steam) generation.
Unlike a gas engine, all of the heat generated by a gas turbine is high grade (>500 C). This makes gas turbines ideal for industrial sites that need high-temperature steam to run their processes. This also allows gas turbines to be used in combined cycle mode (steam is generated off the exhaust and used to drive a steam turbine).
Waste heat boilers utilise the heat in flue gases from combustion processes or hot waste air flows from industrial processes to generate hot water or saturated steam. Due to economic and legislative considerations, waste heat boilers are frequently used in conjunction with gas turbines and combined heat and power units.
Indeck Superheat Boilers Meet Short Term Need for Turnaround, Outages and Emergencies in Petrochemical, Refinery and Processing Industries. Why Select an Indeck Superheat Boiler? Indeck's 75,000 pph superheat boilers have large heating transfer surface areas for increased boiler efficiency and are designed to maintain lower furnace pressure drop.
The combined effect was a loss of heat transfer in the economizer and a rise in the HRSG gas-side pressure drop that significantly reduced steam production. Initially the plant owner thought to replace the entire economizer module with one having a recirculation system to take a portion of the hotter economizer outlet water and return it to the

Each HRSG solution is custom-engineered to meet your desired operating flexibility and performance requirements.
The CHP has a 10-megawatt combustion turbine, a heat recovery steam generator, a 4-megawatt steam turbine, and three natural gas boilers. The plant provides electricity for 70% of the campus and provides 100% of the steam that is needed for heating and cooling for buildings across campus.
This heat is converted into useful thermal energy, usually in the form of steam or hot water. Gas turbines/engines are ideally suited for large industrial or commercial CHP applications requiring ample amounts of electricity and heat. Steam Boiler With Steam Turbine
by heating it with sunlight. • - Turbines are driven directly by gases produced by Hot gases in gas turbines the combustion of natural gas or oil. Combined cycle gas turbine plants are driven by both steam and gas. They gener ate power by burning natural gas in a gas turbine and use residual heat to generate additional electricity from steam.
Steam turbines use high-pressure steam to turn electricity generators at incredibly high speeds, so they rotate much faster than either wind or water turbines. (A typical power plant steam turbine rotates at 1800-3600 rpm—about 100-200 times faster than the blades spin on a typical wind turbine, which needs to use a gearbox to drive a
