Title: Using lime to remove sulphur from fumes and flame - descending in combustion chamber of boiler fired by powdered coal
Inventor: WIESER RUDOLF DR
IPC: F23J15/02
Filed: 1980-01-30
Abstract: In removing sulphur from the fume gases produced in a water-tube boiler fired by coal dust, the fumes descend in one or more vertical tube-lined combustion chambers into which powdered lime is blown through nozzles located below at least some of the burners. Before the flames turn to rise vertically through the parallel flue contg. further heating surfaces, they are intensely mixed by nozzles blowing in combustion air and/or fumes, which may also contain powdered lime. Alternatively mixing is mechanically provided, esp. by a rotary stirrer driven by a motor outside the combustion chamber, the stirrer being cooled by a low pressure fluid such as oil, in a heat exchanger, whose heat is applied to the combustion air, the feed water, or the steam produced. Forcing the flame against its normal thermal lift direction causes more uniform and prolonged passage of fumes and flame, which favours combination of CO2 with the lime.

Title: Moulded part
Inventor: OTANI TAKASHI
IPC: B60R13/04
Filed: 1981-04-09
Abstract: A moulded part in the form of an extruded polymeric hollow profile is described, which can be attached to a substrate at its rear side by adhesive bonding. A plurality of pier-like projections extend from the front wall and/or the rear wall of the hollow moulded part into the cavity and extend in the longitudinal direction of the moulded part. For the mounting of the moulded part on a substrate, the pressure brought to act on the outside of the front wall is transmitted very uniformly through these projections to the rear wall, so that a uniform firm adhesion is ensured over the entire rear wall. If the adhesion decreases with time, it can be restored virtually to its original value by exerting a force on the front wall again.
