Patent EP-0154361-B1 (EP)
IPC: F23N5/00
Filed: 1985-02-01
Granted: 1988-09-14
Abstract: A gas burner comprising a burner plate (3) arranged within a closed combustion chamber (2), a mixing chamber (4) having a gas inlet(5) and an air inlet (6) located at the side of the burner plate reverse to that of the combustion chamber and a fan (7) for feeding the gas-air mixture from the mixing chamber through the apertures of the burner plate in the combustion chamber. The gas burner is provided with a burner plate having a low thermal conductivity, a redox detector (9) arranged within the combustion chamber above the burner plate and an electronic control unit (10) producing one or more output signals for controlling the supply of gas and/or air to the mixing chamber of the burner in response to the output signal of the redox detector being applied to its input. These latter provisions permit the burner to be operated with widely differing loads and gas compositions whilst maintaining an extremely low excess of air in the gas-air mixture resulting in correspondingly low CO- and NOx -concentrations in the exhaust gas of the burner. The gas burner of the invention can be used both in domestic gas appliances for the heating of air of water or for cooking and as a pilot burner for controlling the supplying or oxygen to large industrial burners.

Abstract: An HIPR emulsion of bitumen in water is prepared by a method which comprises directly mixing 70 to 98% by volume of bitumen having a viscosity in the range 200 to 500,000 mPa.s at the mixing temperature with 30 to 2% by volume of an aqueous solution of an emulsifying surfactant, percentages being expressed as percentages by volume of the total mixture. Mixing is effected under low shear conditions in the range 10 to 1,000 reciprocal seconds in such manner that an emulsion is formed comprising highly distorted bitumen droplets having mean droplet diameters in the range 2 to 50 micron separated by thin films of water. The emulsions can be cut back to provide stable emulsions of lower bitumen content which are useful in road-making and the formation of protective coatings.
