Guide on Combined Heat and Power (CHP) Systems
An extremely efficient method, Combined Heat and Power (CHP) traps and uses heat which is actually derived during the process of generation of electricity, only as a by-product.
CHP systems are able to generate power and heat at the same time. Thus, it is able to lower carbon emissions by as much as 30% when compared to other ways of generating electricity through a power station and a boiler.
If you do not know much about CHP systems and how they work, then read on and find out all about them.
Combined Heat and Power Technology
Overall, any CHP plant comprises of an electrical generator along with tools for trapping and using heat that is created by the same generator. A reciprocating engine or a gas turbine can be the prime mover, which would serve as the generator.
It may also comprise of a steam turbine which manufactures power from the steam that is generated in a boiler and kept at high pressure. There are a few cases where a CHP scheme can be a blend of one or more steam turbines, boilers and prime movers.
Below is a great diagram that maps out exactly the process in which a CHP system uses to produce energy.
Operating and Maintaining Combined Heat and Power Systems
When the installation of a CHP package has been done, it has to be properly maneuvered and maintained so as to offer the savings in costs as planned.
There are some types of CHP plants which fail to provide the amount of savings expected, as a result of lackluster maintenance and overall supervision.
Combined Heat and Power and Environmental Problems
In case of any specific CHP plant and its operation approach, the lowering of consumption of primary energy can be based on the energy production and consumption every year.
The emissions arising from the setup and performances of the Combined Heat and Power unit may also be based on the same.
Site Assessment tool for Combined Heat and Power
It is actually a tool which is available free of cost and can help users to assess and review the possible options for setting up CHP system on a specific site.
This type of tool has been devised to be used by people having only a small amount of understanding of how CHP operates. The tool helps users receive and understand the information that is needed for doing an indicative assessment. It can display whether more investigation is necessary in a specific site.
Generally, CHP systems offer an efficiency that is higher than 80%. Usually, operators are able to save as much as 30% on the emissions of carbon.
