World Energy Technology Series 3 – COMBINED HEAT AND POWER (COGENERATION, TRIGENERATION)

Your energy technology and pricing expert is releasing issue #2 on Advanced Coal Technologies.  This series will focus on energy technologies (fossil, renewable, nuclear, storage) by giving information on the energy resource, basic principles, energy conversion technology, overnight capital cost ($/kW), operating and maintenace costs (fixed O&M $/kW/yr, variable O&M $/kWh), maintenance and overhaul schedule (to determine capacity factor and availability), outage rate and reliability, construction lead time, economic life, conversion efficiency (input energy to output power or heat or cooling), fuel heating value (gross and net BTU/lb, kJ/kg, BTU/scf, kJ/Nm3, BTU/gal, kJ/liter), fuel costs ($/MT, $/kg, $/bbl, $/liter, $/MMBTU, $/GJ) in order to arrive at its levelized price and levelized generation cost of energy. The benefits and risks of each technology is also presented. I encourage the reader to follow this series.

A complete power point presentation may also be obtained from this link to complement this article.

Combined Heat & Power (Cogeneration, Trigeneration) – By Marcial Ocampo

Topics – Combined Heat & Power

What is CHP or Cogeneration?

History of Cogeneration

Basic Cogeneration Plant
Extraction-Condensing Turbine

CHP GT with waste heat recovery boiler for heat and electrical power.

Cogeneration Plant Efficiency

Efficiency for Separate Generation

Types of Cogeneration

Topping Cycles

Other CHP Technologies

Opportunities for CHP

Cost of CHP and Distributed Generation Technologies

CCGT for District Heating and Sea Water Desalination

Fuel Cells for CHP

Fuel Cell-IGCC Hybrid

Fuel Cell Concept for Power, Heat and Potable Water

Environmental Impact of CHP:

• •Environmental Impact of CHP Plants

-        The primary environmental impacts are no different

than those of the same plant used solely for power

generation

-        Use of CHP increases the efficiency of energy

conversion process and controls, at least in part, the

release of heat from power plants into the

atmosphere.

Risks with CHP:

• •Technology Risks – associated with CHP are principally the risks that attach to the particular electricity generation technology being harnessed. (These are discussed with their associated technologies)
• •Economic Risks – the addition of CHP to a project should improve its financial viability. Certain industries have recognized this, but more often CHP is avoided.  This may be due to ignorance – fear of the unknown – that translates into a heightened level of risk.

Trigeneration

(power + heating + cooling )
