Combined Heat And Power (CHP) System Cost

Combined heat and power (CHP), or cogeneration, is the simultaneous generation of useful mechanical and thermal energy in a single, integrated system. CHP can be configured as a topping or bottoming cycle. In a typical topping cycle system, fuel is combusted in a prime mover, such as reciprocating engines, combustion or gas turbines, steam turbines, microturbines, or fuel cells, which drives the overall system to generate electricity. In a bottoming cycle system, also referred to as "waste heat to power," fuel is combusted to provide thermal input to a furnace or other industrial process and heat rejected from the process is then used for electricity production.

About combined heat and power system cost not only contains fuel cost and equipment boiler, but also installed cost.

1.Fuel costs depend on the fuel chosen by the customer and the local resources.

2.Equipment cost. CHP system contains many equipment, such as boiler, electronic control system, fuel supply system equipment, slag system, etc., for different equipment manufacturer, the price might be different. The technology, the steel material, the auxiliaries, the production process and the service are different.

3.Installed cost. The installed cost for most CHP technologies consists of the total equipment cost plus installation labor and materials, engineering, project management, and financial carrying costs during construction.

4.Operation and maintenance (O&M) cost.

Non-fuel operation and maintenance (O&M) costs typically include routine inspections, scheduled overhauls, preventive maintenance, and operating labor. O&M costs are comparable for gas turbines, gas engines, steam turbines, and microturbines, and only a fraction higher for fuel cells.
