Power Solutions - Industrial Cogeneration and Combined Heat and Power

##

Combined Heat and Power - What is it? Combined Heat and Power (CHP), or cogeneration, is the simultaneous generation of

electrical or mechanical power and useful thermal energy from a single fuel source.

•Utilize the heat that would have been wasted as steam, hot water, or cold water.

•CHP is not a single technology but an approach to applying various technologies.

Combined Heat and Power Examples

4

Combined Heat and Power Why? - Increased Efficiency and Cost Savings

CHP can:

Increase energy efficiency

Reduce site energy costs

Reduce air pollutant emissions

Enhance site energy reliability

Provide critical power stability

Reduce transmission cost

Delay need for new T&D

infrastructure

Use clean domestic energy

sources (natural gas, biomass,

and biogas)

5

Combined Heat and Power How to use the Heat Generated?

Exhaust gases (800-1000°F)

Steam, Chilled Water, CO2 capture and re-use

Jacket or Heating Water (200°F)

Hot Water, Pre-heat Water, Economizer, Building Heat

Aftercooler Water (130°F)

Building Heat

Major Applications

Industrial

Chemical,

Paper,

Food and Beverage,

Institutions

College & Hospital

Combined Heat and Power Does your site qualify?

CHP is an economic decision and must be evaluated on a case by case basis.

What is the prime objective? Electric or Thermal Heat Demand

Qualifiers:

Extended operating hours (greater than 5,000 hours)

High electric and/or thermal demand

Need to meet standards for energy efficiency (corporate, state or federal)

Environmental Regulation pressure (GHG emissions, Boiler MACT)

Large Spark Spread – Cost of generating power VS. buying from the grid

Replacing or expanding existing steam/heat generator offset

Energy reliability and/or critical power stability offset

Rule of Thumb:

CHP usually makes economic sense if greater than 50% of available thermal

energy can be used on an annual basis.
