摘要： In an electric power generation system (2), there is a cross-flow stack (4) of fuel cells (6) each having an anode, electrolyte, and a cathode. Associated with the anodes are anode passages which in each cell are divided into a first group formed by anode passages (28a) and a second group formed by anode passages (28b). Fuel gas, for example methane from a supply (26) is fed via path (34) to an inlet manifold (38a) to the anode passages (28a), and a portion of anode exhaust gas from the anode passages (28a) is fed via an exhaust outlet manifold (40a) and lines (42, 46) to an inlet manifold (38b) feeding the anode passages (28b). A reforming reaction takes place in the anode passages (28a and 28b). The other part of the anode exhaust gas from the exhaust manifold (40a) is fed via lines (42 and 44) to the line (34) to mix with the fuel gas. Atmospheric air provides the oxidising gas supplied on line (18) to the cathodes. That oxidising gas is heated in a heating arrangement (21) in which anode exhaust gas from the anode passages (28b), and supplied on line (50), is burnt.

摘要： A meter (2) to measure the volumetric flow rate of a liquid, for example water, is formed with a pipe (4) forming a liquid flow path containing a low power electrical heater (12). A temperature sensor (19) measures the temperature T1 of the liquid adjacent to an upstream end of the heater and a temperature sensor (20) measures the temperature T2 of the liquid adjacent to a downstream end of the heater. The heater (12) adds heat power of a value P to the liquid. A control arrangement (18) comprising computer means calculates the flow rate Q using the expression (a) where ST1 and DT1 are respectively the specific heat capacity of the liquid and the density of the liquid at the temperature T1 measured by the sensor (19).

摘要： A method of lining an outer pipe (2) which may be of ferrous metal with a lining pipe (4b) of cross-linked polyethylene initially provided as a precursor lining pipe (4a). The precursor lining pipe (4a) is made by forming an initial pipe of cross-linked polyethylene having an external diameter equal to the internal diameter of the outer pipe (2), then the initial pipe is drawn through a die to form the precursor lining pipe (4a) having an external diameter less than the internal diameter of the outer pipe (2). The polyethylene forming the precursor pipe (4a) is memory material having a material of the outer diameter of the initial pipe to which size outer diameter the precursor pipe (4a) expands automatically when the polyethylene is melted. The precursor pipe (4a) is inserted in the outer pipe (2) and the polyethylene is molten by drawing through the precursor lining pipe (4a) a burner (60) burning fuel gas supplied with combustion air through a hose (58) by which the burner is towed. The hot products of combustion melt the polyethylene causing the precursor lining pipe (4a) to expand automatically into the lining pipe (4b) which is supported, until the polyethylene solidifies on cooling, by gas pressure of a desired predetermined value inside the lining pipe (4b). That gas pressure is derived from the pressure of the gaseous products of combustion which latter pressure may be augmented by the pressure of additional air supplied to the interior of the precursor lining pipe (4a).

摘要： A replacement pipe is installed within an existing service pipe (1) by first advancing a sealing means (6, 8) along the existing pipe to a position adjacent its junction with a main pipe (2), then deploying the sealing means to seal against the inner surface of the existing pipe (in the example shown, by pumping sealant (10) into the space between the seal body (6) and the pipe (1), and subsequently advancing the replacement pipe along the existing pipe. The space between the two pipes is then filled with sealant and finally the sealing means is opened, in the example shown by withdrawing a guide rod (5) and its collar (7) on which the sealing means was advanced into position.

摘要： An energy meter (2) comprises a combustible fuel gas inlet (48) and a fuel gas outlet (50) and a central tube (12) along which the gas flows in travelling from inlet to outlet. Ultra-sound transducers (52 and 54) and a control (56) comprising computer means form a system whereby the speed of ultra-sound signals travelling through the gas between the transducers can be measured and utilised in the control to calculate the volumetric amount of gas which has passed through the meter. The ultra-sound signals pass through apertures (33 and 38) in the walls (24, 26) of chambers (32, 34) containing the transducers. Another ultra-sound transducer (66) in the chamber (32) and connected to the control (56) acts as an emitter and receiver of ultra-sound signals reflected by reflectors (68 and 70). These signals travel through the fuel gas in chamber (32) and their attenuation is observed and measured by the control when they are received by transducer (66). The measured attenuation is used by control (56) to derive the calorific value and/or Wobbe index of the gas, and the control uses the volumetric amount of gas and the calorific value and/or Wobbe index to derive the amount of energy provided by the supply of the gas.

摘要： A method for producing synthesis gas (essentially a mixture of hydrogen and carbon monoxide) from a mixture of methane and oxygen comprising partially oxidising the methane by bringing the reactant gas mixture at a relatively low temperature (100 DEG C to 950 DEG C) and at a pressure of up to 15 bar into contact with a defined nickel - aluminium Feitknecht compound/alumino-silicate clay mineral based catalyst. Resulting synthesis gas may be mixed with further oxygen and be further partially oxidised without being subjected to an intermediate compression stage to produce a second synthesis gas suitable for direct use in a high pressure downstream process for producing a chemical product, such as methanol.
