CHPowerLineTurning wasted energy into useful energy.

 

To meet the growing demand for cogeneration generators, we are proud to introduce our latest line of generators.

Cogeneration, or combined heat and power (CHP), is the simultaneous generation of electricity and useful thermal energy from a single fuel source.

A conventional, engine driven generator set provides electricity and consumes fuel, often diesel or natural gas. Some of the fuel consumed, usually about 30 to 40 percent is converted to mechanical energy to drive an electricity generator. The balance of the fuel consumed, 60 to 70 percent, generates heat. This heat is dissipated to the coolant and radiated directly to the surrounding air.

A CHP generator set also converts fuel to mechanical energy to generate electricity. However, instead of wasting the heat energy, the heat energy is largely captured and transferred into usable energy in a heating system. The heat energy may be used simply for hot water for heating, for cleaning, or for pre-heating for boilers.

Checklist 2Checklist of Things to Consider

For CHP generator sets to be economically feasible there must be a nearby use for the heat rejected by the engine.PDF-Icon 1 darkback 2

CHP works best when the kWe produced by the generator and the demand for heat from the engine (kWt) are both used to their maximum output. Often a good system will be limited by the electrical or heat load. For example, if you require 200 kWt of heat energy and 600 kWe of electrical energy, the most effective system may be to provide 200 kWt and (about) 175 kWe. The balance of the electrical load would remain on the grid.

The following is a list of some of the things that you need to consider for a CHP generator set.

  • What is the voltage, frequency, kWe, kWt?
  • Where will the heat be used (i.e., what is the distance)?
  • How will the heat be be used?
  • Where will the CHP generator set be located—indoors or outdoors?
  • What noise (i.e., sound pressure) levels are acceptable?
  • What are you paying in electrical utility costs?
  • What are you paying in heat energy costs?
  • What fuel source is available?
  • What is the cost of fuel?
  • Can your fuel costs be improved or locked in by contract?
  • What are the access restrictions (e.g., size or weight restrictions especially in buildings)?

There’s lots more to consider.

CHPowerLine Generator Features

Here are some of the key features of our new line of generators.

  • Turnkey cogeneration system fully packaged inside a sound-attenuated and thermally-insulated container.
  • Highly efficient genset based on a Liebherr gas engine and a Stamford generator.
  • Simultaneous production of prime electrical power and thermal power as hot water at 90ºC improves fuel efficiency from 37% to over 80%.
  • Automatic operation control and switchgear included.
  • Silent operation with an average of 75 dBA at 7m using a critical grade muffler and custom acoustic-designed air inlet and discharge ducting.
  • Low engine emissions of NOX, CO and HC make the package very environment friendly.
