Device adaptive control of expansion turbines

Abstract: FIELD: oil and gas industrySUBSTANCE: invention relates to a turbine building art, namely to devices regulating turbines and can be used at gas distribution plants for the recovery of the pressurized gas energy and electricity generation The device comprises a lock and the bypass valves with actuators and position sensors, regulator, switch modes, normalizing and scaling amplifiers, comparison blocks, pressure sensor in the line of low pressure, the load sensor of the external electric network, the adder, the frequency-adjustable wrench, an electric gas heater , setting devices of the maximum and minimum load values in electrical circuits, external power supply and gas heater, Schmidt triggers, reversible counterEFFECT: invention provides an increase in reliability of the turbo expander by mechanical load on its shaft stabilization, when the electrical load fluctuations in the external power supply through the redeployment of the electrical energy in the natural gas heating in the input line system1 dwg

Gas heater with electric heating device

Abstract: The utility model discloses a gas heater with an electric heating device. The gas heater comprises a casing, a catalytic combustor, a combustor heat insulating blade and a gas cylinder heat insulating board. A panel is of an upper opened frame shape from a plant view; a plurality of heat radiating holes are formed in the front part and the side part of the panel; the gas heater also comprises an electric heating wire and a cross-flow fan, wherein the upper end of an outer cover of the cross-flow fan is fixedly connected with a fan mounting plate; the fan mounting plate is fixedly connected with a top plate of the casing; the outer cover of the cross-flow fan is fixedly connected with the gas cylinder heat insulating plate; the gas heater further comprises a fan mounting port; and the electric heating wire is arranged between the cross-flow fan and a hear air outlet. Due to the adoption of the structure, the heat generated by the catalytic combustor can be quickly radiated from the front side and the two sides, so that the heat efficiency is increased; due to the setting of an electric heater, the catalytic combustor can be independently used or the electric heater can be independently used or the catalytic combustor and the electric heater can be simultaneously used, and further the convenience in use is realized; and when the electric heater is in use, the heat of the electric heater can be radiated from the top of the casing or simultaneously radiated from the front side and the two sides of the front panel.

Self-circulation energy-saving energy supply system of LNG transport ship

Abstract: A self-circulation energy-saving energy supply system of an LNG transport ship comprises supports, a cabin, a first valve, a gas storage tank, a first pipe, an air cylinder, support rods, a suction pipe, a support plate, a transition tank, a second valve, a second pipe, a column, an exhaust pipe, a rubber block, a moving block, a linear motor, a fourth valve, a test tube, a liquid tank, a third pipe, second exhaust fans, a third valve, a first gas collecting tank, a circulating pipe, a gas heater, a second gas collecting tank, a second motor, a fisheye bearing, a support block, a controller, two rolling wheels, first motors, a wheel carrier, a belt and first exhaust fans. The gas storage tank is connected with the gas heater through the first pipe. The gas heater is installed in the cabin. The first valve is installed on the first pipe. The wheel carrier is installed on the top in the cabin. The two rolling wheels are installed on the wheel carrier. A shaft of each rolling wheel is connected with the corresponding first motor through a coupler. The first motors are installed on the wheel carrier. The self-circulation energy-saving energy supply system of the LNG transport ship has the advantage of having the energy saving effect.

Heat exchanger and scrubbing system for flue gas

Abstract: In the appts, a raw gas cooler (8) supplies cool gas (aROG) to the gas scrubber (5) This enters the scrubber low over its sump (11) Behind the scrubber, a gas heater (20) receives the now clean, cool gas (kREG) leaving the scrubber (5) at the top (12) A thermal fluid (25) recirculates in closed circuit, between cooler (8) and heater (20) The raw gas cooler (8) and clean gas heater (20) pref have concentric rings of vertical tube bundle (7, 22) modules (6, 21), of plastic; fastened together Thermal medium flows inside the tubes, gas outside In the clean gas heater (20), the gas (REG) flows down a central shaft (15), which has incoming hot dirty gas (ROG) outside
