Producing Là Gì

CHP.. is an energy efficient technology that generates electrithành phố and captures the heat that would otherwise be wasted lớn provide useful thermal energy—such as steam or hot water—that can be used for space heating, cooling, domestic hot water and industrial processes. CHPhường can be located at an individual facility or building, or be a district energy or utility resource. CHP is typically located at facilities where there is a need for both electriđô thị and thermal energy.

Nearly two-thirds of the energy used by conventional electricity generation is wasted in the khung of heat discharged to lớn the atmosphere. Additional energy is wasted during the distribution of electricity lớn over users. By capturing và using heat that would otherwise be wasted, & by avoiding distribution losses, CHPhường can achieve sầu efficiencies of over 80 percent, compared khổng lồ 50 percent for typical technologies (i.e., conventional electriđô thị generation & an on-site boiler).

Common CHPhường Configurations

The two most common CHP system configurations are:

Combustion turbine, or reciprocating engine, with heat recovery unitSteam boiler with steam turbine

Combustion Turbine, or Reciprocating Engine, with Heat Recovery Unit


*

Combustion turbine or reciprocating engine CHP systems burn fuel (natural gas, oil, or biogas) to turn generators lớn produce electrithành phố and use heat recovery devices khổng lồ capture the heat from the turbine or engine. This heat is converted into useful thermal energy, usually in the size of steam or hot water.

Steam Boiler with Steam Turbine


*

With steam turbines, the process begins by producing steam in a boiler. The steam is then used khổng lồ turn a turbine khổng lồ run a generator to produce electriđô thị. The steam leaving the turbine can be used khổng lồ produce useful thermal energy. These systems can use a variety of fuels, such as natural gas, oil, biomass, và coal.

CHPhường Applications

CHP is used in over 4,400 facilities nationwide, including:

Commercial buildings—office buildings, hotels, health clubs, nursing homesResidential—condominiums, co-ops, apartments, planned communitiesInstitutions—colleges & universities, hospitals, prisons, military basesMunicipal—district energy systems, wastewater treatment facilities, K-12 schoolsManufacturers—chemical, refining, ethanol, pulp & paper, food processing, glass manufacturing

A number of site-specific factors will determine if CHP.. might be a good technical and economic fit for your facility. Answer a few simple questions to lớn determine if your facility is a good candidate for CHPhường.
