Efficient and low-carbon, synergy and mutual assistance | ENN Power's "cooling, heating and power triple generation" solution based on micro and small gas turbines
Combined Cooling, Heating & Power (CCHP) is a distributed energy system built on the user side, using natural gas as the main fuel, using gas turbines or gas internal combustion engines to burn natural gas for power generation, and further recovering waste heat after work for cooling, heating and domestic hot water. Through the method of combined cooling and heating, the cascade utilization of energy is realized, and the comprehensive energy utilization efficiency can reach more than 90%, which is an important way to efficiently utilize natural gas. At present, the use of cold and heat power combined power system has been quite common, mainly used in hotels, hospitals, shopping malls, office buildings, schools, airports and other public place facilities.

ENN Power is based on micro and small gas turbines
Combined cooling and heating and power solutions
✓ Realize the efficient conversion of energy through the use of energy cascades and reduce the energy cost of customers
✓The energy station is close to the user side, which can match the production capacity and energy consumption and reduce the transmission loss
✓ Improve the reliability and flexibility of energy supply
✓ For users with insufficient capacity, the capacity can be compensated by gas turbine power generation
✓The average annual comprehensive energy utilization rate of cooling, heating and power is generally 75%~92%, and if there is a suitable cold source on site for the cascade utilization of flue gas exhaust heat, the comprehensive energy utilization rate will be higher
✓ Efficient - continuous breakthroughs in core technologies
Micro and small gas turbines with completely independent intellectual property rights, the performance has reached the international advanced level, high-speed motors and air bearings have continuously made breakthroughs in international advanced technology, and the heat recovery adjustable technology has greatly improved the flexibility of the system to adapt to load changes. The system can output cold/hot, hot water and electricity at the same time, realizing the stepped utilization and comprehensive supply of energy, and the comprehensive utilization efficiency of energy can reach more than 90%, which is an efficient way of comprehensive energy utilization and saves energy costs for users.
✓ Low nitrogen – dry low-emission combustion technology reduces NOx emissions
ENN Power Gas Turbine Combustion Chamber adopts centrally graded premix low-emission technology, which controls nitrogen oxide emissions by controlling the temperature and distribution of the combustion zone, while reducing carbon monoxide and unburned hydrocarbon emissions by controlling the residence time. The natural gas combustion process produces almost no SOX and dust, and produces less NOX than other fossil fuels, and the total emission of nitrogen oxides (NO and NO2) is controlled within 15 ppm.
✓ Carbon reduction – The energy utilization efficiency of the gas turbine triple power system can reach more than 91%
The carbon factor generated by power generation can be as low as about 0.3tCO2/MWh, while most of the electricity in the power grid is coal power, the comprehensive energy utilization rate is low, and there is line loss, the carbon factor is generally about 0.8-1tCO2/MWh, and the carbon reduction can be achieved by more than 20% through the gas turbine triple power system.
✓ Intelligent - remote intelligent operation and maintenance platform allows customers to save worry and effort
ENN Power has successfully built a remote intelligent operation and maintenance platform for gas turbines, which realizes equipment operation, energy consumption, energy efficiency supervision and optimal control through the combination of digital technology and energy technology. The collection of energy consumption data, equipment operation status data, and operating environment data of terminal energy-consuming equipment in real time, through the platform's data calculation and big data analysis and processing, provides enterprises with energy services such as integrated energy online monitoring, energy efficiency analysis and energy saving, and integrated operation and maintenance of centralized control, which can better help users reduce costs and increase efficiency, save energy and protect the environment while improving the energy management level of enterprises.

✓ Generate high-value electricity from gas while making full use of waste heat to generate significant benefits
✓ On the one hand, the customer's capacity fee can be reduced by reducing the power capacity, and on the other hand, the power capacity fee of the cooling equipment and the one-time investment of the power distribution equipment are reduced
✓ Gas turbine power generation equipment can maintain part of the power load operation in the event of a power outage, which can reduce the investment of backup power supply
✓ It has a good effect of energy conservation, emission reduction and carbon reduction, which is in line with the theme positioning of the park as green, energy-saving and environmental protection
✓ It is conducive to power peak shaving. When meeting peak electricity consumption, gas cooling, heating and power combined power can also use waste heat for cooling, further slowing down the electrical load demand of electric chillers. At the same time, the gas turbines of gas combined power projects have good load response characteristics, which is also conducive to the instantaneous adjustment of the power grid
✓ Can be coupled with other energy sources. Gas cooling, heating and power triple generation technology is advanced and mature, with strong integration, and can be friendly with biomass, solar energy, geothermal energy, residual pressure waste heat and gas and other energy forms to achieve coupling and complementarity, thereby driving the consumption of new energy
The main application scenarios of the combined cooling and heating power solution based on micro and small gas turbines are: public buildings with cold and heat load requirements or perennial hot water load demand; users with high power supply requirements; users with difficulty in power access; users who need backup generators; Under the current policy and price conditions, users in hotels, comprehensive commercial and office buildings, airports, transportation hubs, entertainment centers, industrial parks and other users are suitable for the use of triple power supply systems.
