1. Efficiency: The primary goal of cogeneration is to maximize the efficiency of the overall energy system. Thus, the design should aim to minimize energy losses and waste by optimizing the use of heat and power.
2. Technology selection: The selection of the appropriate technology for cogeneration depends on multiple factors such as the type of fuel, project scope, load profile, etc.
3. Safety and environmental considerations: Industrial cogeneration facilities must meet stringent safety and environmental standards. Safety considerations should include the proper management of combustible materials, fire protection measures, explosion-proofing, etc. Environmental considerations should include reducing air emissions, treating waste streams, and adhering to local regulations.
4. Maintenance and reliability: To ensure continued operation and maximum efficiency, cogeneration facilities must be designed for ease of maintenance and optimal reliability. This includes ensuring adequate access for maintenance, selecting equipment with high reliability, and implementing a comprehensive maintenance program.
5. Integration with the electricity grid: For grid-connected cogeneration facilities, integration with the local electricity grid is critical. The facility must be designed to meet the local grid's requirements and regulations for connection, operation, and control.
6. Economic considerations: The economics of industrial cogeneration projects are complex and dependent on multiple factors. The design should incorporate considerations such as the cost of fuel, electricity prices, capital costs, and available incentives.
7. Load management: Cogeneration facilities must be designed to manage changes in loads on both the electricity and heat sides. This requires a flexible design that can adapt to changes in demand and optimization of the system.
8. Energy storage: Cogeneration facilities can benefit from an energy storage system to improve efficiency and increase flexibility. The design should include considerations for energy storage capacity, system selection, and location.
