  • Patent number: 10465565
    Abstract: A CO2 energy storage system includes a storage tank that stores a CO2 slurry, including dry ice and liquid CO2, at CO2 triple point temperature and pressure conditions. The storage system also includes a first pump coupled in flow communication with the storage tank. The first pump is configured to receive the CO2 slurry from the storage tank and to increase a pressure of the CO2 slurry to a pressure above the CO2 triple point pressure. The energy storage system further includes a contactor coupled in flow communication with the first pump. The contactor is configured to receive the high pressure CO2 slurry from the pump and to receive a first flow of gaseous CO2 at a pressure above the CO2 triple point pressure. The gaseous CO2 is contacted and then condensed by the melting dry ice in the slurry to generate liquid CO2.

  • Patent number: 10458082
    Abstract: The truck snow-melting system comprises a pair of three-port diverting valves which may, under electrical control from within the cab of a truck, be transitioned between directing exhaust gases out of the vehicle's exhaust pipe and directing exhaust gases to a left transport pipe and a right transport pipe. The left transport pipe directs exhaust gases to a left exhaust outlet located in front of driven wheels on the left side of the truck and the right transport pipe directs exhaust gases to a right exhaust outlet located in front of driven wheels on the right side of the truck. The exhaust gases melt wintery precipitation so that the truck may gain traction. A plurality of adjustment points allow the horizontal and vertical positions of the exhaust outlets to be changed.

  • Patent number: 10443842
    Abstract: The present disclosure provides a method for controlling combustor cans of a gas turbine. Detectors disposed on combustor cans are operable to detect combustion vibration values of the combustor cans. The combustion vibration value is compared to a reference value. Combustor cans having a combustion vibration value greater than a reference value are assigned to a first group, and combustor cans having a combustion vibration value not greater than the reference value are assigned to a second group. The output of each combustor can in the first group is regulated to lower the combustion vibration value, thereby improving the stability of the gas turbine.

  • Patent number: 10415538
    Abstract: A negative-pressure wave generator has a flow-driven assembly and a power-generating assembly disposed in the sea. The flow-driven assembly has multiple Venturi tubes connected to a power generating culvert of the power-generating assembly. The power generating culvert has a generator assembly. When sea water passes, the Venturi tubes generate negative pressure to make the water flow into the flow-driven assembly from the power generating culvert. A large pressure difference is formed between outside sea water out of a turbine disposed in a front end and a chamber disposed in a rear end, and the pressure difference drives the turbine to drive the generator assembly. The transferring efficiency is high and the water in all the flow channels is in low pressure to prevent the water pipes from burst and leakage. The negative-pressure wave generator is simple in structure and solid, lowering the maintenance cost.
