A Case Study on a Rice HuskCogeneration Power Plant

Presentation Outline

• Cogen3 Programme

• Cogeneration: How Does It Work?

• Angkor Prosperous Rice Mill

• Environmental and Economic Benefits• Conclusion





Cogeneration

Cogeneration (Combined Heat andPower or CHP) is the simultaneous

production of electricity and heat,both of which are used.





Angkor Rice Mill

Location Map of Angkor Rice Mill





Angkor Rice Mill





The rich, fertile soil of Central Cambodia provides optimal

environment for growing Neang Malis rice





Angkor Rice’s carefully selected planting area is in four provinces

in Central Cambodia: Kandal, Kampong Speu, Takeo and Kampot





A farmer transplanting seedlings





The region’s (central Cambodia) naturally fertile and sandy soil

enables farmers to grow Angkor Rice’s premium-quality Neang

Malis rice in a traditional way without chemicals.





More than 25,000 families are Angkor Rice’s members and growing

Neang Malis rice. There are no middlemen. Angkor Rice sets a

high standard. The Agriculture Division distributes high quality

seeds and instructs the farmers in planting rice.





Products of Angkor Rice: 100% Neang Malis





Proposed Rice Husk-Fired Cogeneration Power Plant

Angkor Rice Mill

• Steam turbine system with 1 MW electric capacity

• Present capacity of the mill is 10 tons/hour. Proposed

expansion of another 10 tons/hour

• Rice husk will be used as fuel• Two scenarios:

– steam has no value

– steam has value equal to 50% of the cost for steam

generation in a boiler using fuel oil

• Excess Electricity exported to other customers

• Utilization of heat for drying






Angkor Rice Mill

Scenario: Steam has no value• Total Investment Cost including contingency: 1.5 million euro

• Net Present Value: 3.1257 million euro

• IRR: 49.7%

• Discounted Payback Time: 2.3 years

• Cogeneration Project Lifetime: 20 years






Angkor Rice Mill

Scenario: Steam has value equal to 50% of fuel

oil cost• Total Investment Cost including contingency: 1.5 million euro

• Net Present Value: 4.659 million euro

• IRR: 64.4%

• Discounted Payback Time: 1.6 years

• Cogeneration Project Lifetime: 20 years





Cogen3 Pre-evaluation and Recommendations

• Project seems feasible

• Further investigations are recommended, concerning: – detailed design (electricity capacity of steam turbine,

utilization of capacity) – necessary investment

– real value of steam (benefits of drying using steam)

– necessary investment in drying process

– necessary investment in electricity distribution grid

– all issues, (especially government regulations) related toselling of electricity to other parties

• Requires a full feasibility study and investigation





Benefits of the Rice-Husk Cogeneration

Power PlantEnvironmental Benefits• Less pollution

• Uses rice husk, which is considered an agriculturalwaste

Economic Benefits• Savings (electricity production)

• Income generating (selling excess electricity, ashsales)

• Generates job

• Saves on fuel, no foreign currency needed
