Title: Boiler with fine gas return flow - has temperature sensor to control cooling air flow to limit flue gas temperature
Inventor: STROEER KURT DIPL ING
IPC: B02C13/288
Filed: 1991-07-26
Abstract: A boiler, which is fired with pulverised coal, can divert some of the flue gases (3) for mixing with combustion air. The flue gases flow through the duct (42) to return to the air inlet of the boiler combustion chamber. To prevent overheating of the outlet from the pulverising mill, a temperature sensor (6) is fitted in the wall of the flue gas duct (42). This temperature sensor controls an actuator (22) which in turn controls the flow of cold air through the ducts (8) and (15) and thus controls the temperature of the flue gases in the duct (42). USE/ADVANTAGE - Control of return flow flue gas temperature and at the same time control of the temperature of the combustion air.

Patent DE-4239362-A1 (DE)
Inventor: BECK ERHARD DIPL ING
IPC: F04B1/04
Filed: 1992-11-24
Abstract: The invention relates to a valve for high-pressure radial piston pumps suitable for controlled braking systems. Prior art units of this type consist of at least 5 components. It is the aim of the invention to provide a valve requiring fewer components and is therefore simpler and easier to assemble. This aim is achieved in principle in that cold-extruded joining elements are used between the valve and the housing (1) rendering separate rubber seals superfluous and provide a firm, uniformly unbreakable joint. In advantageous embodiments, some of the prior art valve components are made as one piece and the number of cold-extruded joining elements is reduced.
