The Power of Micro CHP CAB 2014 Combined Heat & Power Amaury de Laforcade NSC USA Inc.
An Entrepreneurship history Founding of the N. Schlumberger & Cie in 1810 with a cotton spinning mill in Alsace, France Later on they created Schlumberger Oil Services, the Schlumberger-Mallet bank and the Schlumberger metering devices as well as others entities
Designing & Manufacturing of equipment for the Process of long staple fiber, Non-Woven, Paper and Packaging Industry for more than 200 years, In addition, NSC develops projects in the field of recycling and energy
What is CHP ? Cogeneration or CHP is the use of a heat engine or power station to Simultaneously Generate Electricity and Useful Heat (from Wikipedia)
Thomas Edison and its 1882 Pearl Street Station, the world’s first commercial power plant and CHP plant.
What is CHP ?
7% of the US electricity capacity is from CHP systems
What is Micro CHP ?
Heat Load
To the Micro-grid
UPS & Electrical Load
Natural Gas NaturalNatural Gas Gas
CHP #1
Boiler
CHP #2
Absorption Chiller
HVAC / Cooling
How does CHP works ?
Highly Efficient System by mean of Reciprocating Engine & Thermal exchanger(s)
What is Micro CHP ?
800MWe…..80kWe
10-500kWe was not a priority range
3kWe…..0.3We
What is efficiency ? ‘‘Mileage’’ ‘‘ Profit ’’ ‘‘ Savings ’’
“Obviously, the highest type of efficiency is that which can utilize existing material to the best advantage.” Jawaharlal Nehru
“Washington is a city of Southern efficiency and Northern charm.” John F. Kennedy
What is efficiency ? When thinking Efficient think Effectiveness!!! (Elec power + Recovered Thermal power) Efficiency % = ? Keep thinking costs Available Power and performances
High efficiency CHP units range from 66 to 92 %
CHP advantages ? Centralized Power Generation 40% Efficiency
Co-Generation goes up to 92% Efficiency with TEMA HEAT Losses – 10%
HEAT Losses – 50% Electricity – 30%
FUEL 100%
FUEL 100%
POWER PLANT Line Losses – 10%
Electricity – 40%
CO-GENERATION
Heat Recovery – 60%
With the CHP, the energy released from the fuel is maximized, while reducing Energy waste, Energy bills & Greenhouse gas emissions
CHP advantages ? Efficient System Cost Effective Use of Natural Gas Power Supply Security UPS Functionality (Un-interrupted Power Supply) Peak Shaving Easy to Operate Flexibility (adaptable to your needs) Reduce carbon foot print
Why should we think CHP ? 1. Use of Thermal Power (Boiler, Oven, Dryer, Calender, A/C) 2. Reduce energy costs (Use of Natural Gas, Efficiency, Peak Shaving, Incentive benefits,…)
3. 4. 5. 6.
Energy autonomy Manage UPS load Process of critical products (Delivery time, Food,…) Minimizing our Carbon Footprint Just one of those reasons can be sufficient
Why should we think CHP ? Other good reasons:
Abundancy of Natural Gas Electricity price is linked to Natural Gas price Aging of US transmission lines and infrastructure (the Grid) Development of Smart Grid Government Incentives Need to be ahead of the energy providers Higher Energy Costs
Push for more Efficient Systems
Less Consumption in Fuel/Natural gas
Less Tax revenue
Increase of Fuel and Energy
Things to look for ? Analysis of the situation Identification of your thermal usage: hot water, air?
The primary output of the CHP is hot water to be converted Additional heat exchangers: liquid to liquid or liquid to air
Quantity of heat per hour: BTU / hr (for the said process to be supplied by CHP) Costs of your thermal demand per year Hours of operation per day / week / year the more you run, the faster your payback will be
Things to look for ? Analysis of the situation Utility bills Costs of kW/hr
Costs of electrical black-out Size of the UPS load Electrical base load Cost of Electrical Demand Electrical Peak lengths
Peak shaving savings
Things to look for ? From the Solution Appropriate sizing based on Thermal demand & Consumption. Most of the manufacturer have Systems from 30 to 150kW electric (60 to 300kW thermal). Not subject to temperature changes (reciprocating engine) Higher ratings can be achieved by coupling multiple units
