1.What is the Combined Heat and Power(CHP)?

Combined Heat and Power system is an efficient energy utilization technique, it produces power and thermal energy in a system, improving energy utilization efficient. Compared with traditional power generation methods, CHP can recover and use the waste heat generated during the power generation process. Increase the overall energy utilization rate from 30%-50% of traditional power generation to 70%-90%.

2. Why Combined Heat and Power(CHP) become increasingly popular in industrial, commercial, and district heating

By simultaneously generating electricity and heating, what appears to be an efficiency level often approaching 80% is seemingly attainable. What also appears significant is that, compared with conventional thermal methods, Combined Heat and Power may reduce certain pollutant emissions. From this perspective, what appears to follow from this higher efficiency is a corresponding potential for lower energy costs and improved economic benefits. Furthermore, what seems to result from these considerations is an apparent enhancement in energy supply stability, particularly when they function as what might be characterized as part of a distributed energy system.

3.Basic principles of CHP system

Fuel (such as natural gas, biomass, hydrogen, etc.) drives power generation equipment (such as gas turbine, fuel cells, or internal combustion engines) to generate electricity. The waste heat generated during the power generation process is recovered and used for heating or industrial steam demand.

4. Advantages compared to traditional power generation system

• High energy utilization efficiency: The energy utilization efficiency of CHP systems can reach more than 80%, while traditional power generation systems usually only have 30% -50%.
• Reduce energy loss: The CHP system is close to the user end, reducing energy loss in transmission and heat transfer.
• Environmentally friendly: CHP system reduce environmental pollution and greenhouse gas emissions by comprehensively utilizing the energy of fuels. In addition, the CHP system can flexibly adjust the ratio of power generation and heating according to user needs, further improving the system's economy and adaptability.

5.Feasibility analysis before constructing a CHP system

5.1Energy demand assessment

Electricity consumption: Evaluate the user's electricity demand, including peak, valley, and average electricity consumption.

Thermal energy demand: Evaluate the user's thermal energy demand, such as the amount and temperature requirements of steam, hot water, etc.

5.2 Fuel analysis

Natural gas: clean, efficient, suitable for most CHP system.

Coal: Traditional fuel with lower cost, but environmental protection issues need to be considered.

Biomass: Renewable energy, environmentally friendly, but requires a stable supply source. When choosing fuel, it is also necessary to consider the stability of fuel supply, price fluctuations, and future sustainability

6.Selection of various components of CHP system

6.1 Boiler

Type selection: Choose a suitable boiler based on fuel type and thermal energy requirements, such as gas boilers, coal-fired boilers, etc.

Capacity matching: The capacity of the boiler should match the thermal energy demand of the system to ensure the economic and reliable operation of the system.

6.2 Steam turbine

Efficiency: Choose a high-efficiency steam turbine to improve the overall efficiency of the system.

Flexibility: Consider the load regulation capability of steam turbines to adapt to different thermal energy demands.

6.3 Generator

Power matching: The power of the generator should match the power generation demand of the system to avoid excessive or insufficient equipment.

Reliability: Choose a high reliability generator to ensure the stable operation of the system. In addition, the maintenance cost and service life of the equipment need to be considered to reduce the long-term operating costs of the system.

7.Common application scenarios

• Industrial manufacturing, such as chemical industry, paper making and other factories, need a large amount of thermal energy and power. CHP system can provide stable heating source supply, thereby helping enterprise reduce production costs.
• Commercial buildings, such as hotels, shopping malls, office buildings, etc., require stable electricity and heating. CHP system can meet these needs while reducing energy waste.
• Regional energy supply system: Urban centralized heating/cooling to improve energy utilization efficiency. CHP system can significantly reduce energy consumption, improve the reliability and economy of heating in regional heating.

8.Summary

CHP system significantly improves energy efficiency by simultaneously producing electricity and heat energy. Before constructing a CHP system, need to consider a detailed feasibility analysis, including energy demand assessment and fuel analysis. Choosing the right boiler, steam turbine, and generator is the key to the success of the system. CHP system has broad application prospects in industrial, commercial, and regional heating, which can help enterprises reduce costs, improve energy independence, and achieve sustainable development goals.
