Cogenerating Heat And Power (CHP)
Combined heat and power is generally referred as Cogeneration or CHP. It is a system that makes better use of many types of fuels that is used to produce electricity. Electricity can be generated by an engine that is powered by fossil fuels, Bio-fuels or natural gas; alternatively electricity can be produced by the use of a steam turbine, the steam being produce using the same fuels. Cogeneration system uses the heat produced in the process of generating electricity; CHP captures some or all of the by-product heat for heating district housing or commercial building
Types of Cogeneration (CHP)
Large thermal power plants that generate electricity are the most common type of cogeneration.This uses steam or hot water, with temperatures ranging from 80°C to 130°C to produce electricity. Typically, steam is produced by passing the water through a steam turbine, this heats the water which then is used to produce electricity. This hot water than is further used to heat near-by homes and commercial buildings. However CHP is most efficient when used on site or close to it, the system loses efficiency over long distances because of the need to use heavily insulated pipes which are expensive and inefficient. In older Thermal power plants the heat was released into the natural environment using cooling towers or other means.
Micro CHP, has a Bio-fuel or vegetable oil adapted engine and can be used by individual homes or farms. The engine drives an electric generator which provides electricity for the home or farm. Any surplus of electricity can be fed into the national grid if the plant is near to the grid network. The hot water can be then used for heating the home or the farm. The exhaust gases produced by these engines can be also used for heating; exhaust gases can be passed through specialized radiators with fans attached to produce warm air heating.
Theses micro CHP electricity generating plants are usually manufactured as a complete package, this make installation simple.
In Europe, 11% of the electricity produced is by using cogeneration technology. Denmark, the Netherlands and Finland are the leading countries in cogeneration but other European countries also make a great effort to support cogeneration and increase its efficiency
