The present invention discloses a method of a mobile power generation system. A power generation apparatus is respectively quickly connected, through expansion joints, to an intake assembly and an exhaust duct which are separately transported, to implement the quick installation and connection of the power generation system at the fracturing operation site. Two conveyances are respectively provided for the intake assembly and the exhaust duct to achieve more flexible adjustment during connection. While the position of the power generation apparatus is fixed, the intake assembly is moved to connect to an intake chamber of the power generation apparatus, and the exhaust duct is moved to connect to an exhaust collector of the power generation apparatus.

A control device for a two-shaft gas turbine power generation facility includes: a basic output calculation unit which obtains a basic output command value in accordance with a required output; a component separation unit which divides the basic output command value into high and low frequency components; an opening degree command output unit which obtains an opening degree of a fuel adjustment valve and outputs an opening degree command to the fuel adjustment valve; a basic power transmission and reception amount calculation unit which obtains a basic power transmission and reception amount of the electric power between an induction motor and a power system on the basis of the high-frequency component; and a power transmission and reception command output unit which outputs a power transmission and reception command indicating a power transmission and reception amount in accordance with the basic power transmission and reception amount to a frequency converter.

A system mounted on a skid for use in fracturing operations is disclosed along with an associated method. The system includes a line heater on the skid to enable heating of fuel to be used with a turbine generator and includes one or more pressure regulators coupled to the line heater to enable adjustment of a pressure associated with the fuel.

A micro gas turbine equipped with a valve mechanism by means of which the operation of the micro gas turbine can be influenced and optimized, particularly by regulating a supply of hot gas from the cabinet and/or the exhaust of the micro gas turbine to an inlet side of the compressor. When the temperature of ambient air is relatively low, thermal output and thermal efficiency of a micro gas turbine decrease. The present micro gas turbine compensates for the loss of thermal efficiency.

The invention relates to a plant complex for steel production comprising a blast furnace for producing pig iron, a converter steel mill for producing crude steel, a gas-conducting system for gases that occur in the production of pig iron and/or in the production of crude steel, and a power-generating plant for electricity generation. The power-generating plant is operated with a gas that comprises at least a partial amount of the blast-furnace top gas that occurs in the production of pig iron and/or a partial amount of the converter gas. According to the invention, a chemical or biotechnological plant is provided and connected to the gas-conducting system and arranged in parallel with the power-generating plant with respect to the gas supply. Externally obtained electricity and power-generating plant electricity are used to cover the electricity demand of the plant complex.

A microscale energy cogeneration system comprising at least one micro/nano-turbine for converting fuel into mechanical energy and a generator for converting mechanical energy produced by the micro/nano-turbine into electrical energy in the range of 1 to 5 kWh. Compressed air passes through a cold side of a heat exchanger. The compressed cold air and fuel delivered to a combustion chamber drives the turbine. At least one heat exchanger receives high temperature exhaust gas from an exhaust passage downstream from the micro/nano-turbine for heat transfer. The heat exchanger can be used to heat water and/or air of a house. A water heating system can be coupled to the heat exchanger for converting tap water into potable hot water and/or converting cool air into hot air. The portable micro/nano-turbine set can be scaled up by interconnecting several units to a network for balancing out the energy demand of multiple users.
