Application scenario

The micro-turbine-based combined heat and power (CCHP), which uses natural gas as the main fuel to drive the operation of the gas turbine, generates electricity to supply the user's power demand, and the waste heat discharged after the gas turbine generates electricity to the user through the bromine cooler to the air conditioner. The system supplies heat or cooling, and the flue gas discharged from the bromine cooler is then exchanged by a heat exchanger to obtain domestic hot water. In this way, the cascade utilization of energy is realized, and the primary energy utilization rate of the entire system is greatly improved; meanwhile, the emission of atmospheric pollutants is small, and it is an efficient comprehensive energy utilization method. In principle, the power consumption of the system is mainly for self-use, and the grid is not connected to the Internet. As the peak shaving and emergency response of the power grid, it not only increases the economic benefits of the entire system, but also improves the security and stability of the power grid. In addition to using natural gas as fuel, it can also be adapted to local conditions using biomass gas, biogas, diesel and other fuels.

system introduction

INTRODUCTION OF CCHP

-------------------------------------------------- ---------------------------

The system uses Xinao Power's self-developed micro gas turbine as the core power, plus a bromine chiller and a heat exchanger. The electricity generated by the gas turbine is not connected to the grid and is completely consumed by the user. The insufficient electricity is supplemented by the power grid; the high-temperature flue gas of the gas turbine enters the bromine cooler to generate cold or heat, which fully meets the user's cold / hot demand; After the flue gas has some residual heat, it can be exchanged for hot water through a heat exchanger. In order to make the bromine cooler operate at the highest efficiency point, the micro-burner is set to adopt a partial regenerative method to make the exhaust temperature at 500 ° C.

Combined heat and power (CHP) with a gas turbine as its core, mainly refers to natural gas as the main fuel, and first uses the gas turbine to generate power, and the high-temperature flue gas generated is generated by the waste heat boiler for users, or the high-temperature flue gas thermal energy is used directly Compared with the method of separately producing electricity and heat energy, users can effectively avoid the heat loss caused by simple heating or power generation, and greatly improve the energy efficiency and utilization efficiency. At the same time, gas turbine emissions are very low and have excellent environmental benefits. In addition to using natural gas fuels, fuels such as biomass gas, coal bed gas, and blast furnace gas can also be adapted to local conditions. Generally, there are two main methods of cogeneration: one is that the user has steam demand, and then combines the waste heat boiler to generate steam; the other is that the user directly needs the high-temperature flue gas, which is directly supplied to the user.

A jewelry factory in Jinhua City, Zhejiang Province. The factory mainly produces resin drills. In the processing of workpieces, hot air is often used to dry the workpieces. The original plan was to equip each oven with a combustion furnace to burn biomass particles to generate hot air. The factory now has 32 ovens and requires xxx heat. The original burning biomass particles scheme is very polluting and faces great environmental pressure. After switching to the micro gas turbine solution, a large amount of waste heat in the exhaust gas of the micro gas turbine is used for drying. Due to the low emissions of flue gas pollutants, the environmental protection problem is solved. At the same time, the electricity generated by the micro gas turbine can be used for the factory's own use, which has been eased The pressure on the transformer capacity of the factory.
