A water cooled kiln comprises a cylindrical combustor structure made up of a plurality of generally parallel water pipes spaced circumferentially about the periphery of the structure, and a plurality of webs circumferentially interconnecting the pipes so as to present the cylindrical combustor structure. The webs are provided with openings so that combustion air may flow therethrough and into the combustion chamber defined by the cylindrical combustor structure. The webs are protected from corrosion and erosion by the provision of a protective sheet constructed of a corrosion resistant material which is placed in covering relationship to the web inside the chamber. The protective sheet is spaced slightly from the web by dimples or corrugated strips and is attached to the web by spot welding for example. Air proceeding toward the combustion chamber enters through the opening in the web and is diverted by the protective sheet so that the air flows through the plenum between the web and the sheet and cools both the web and the sheet to diminish the corrosive and erosive effects inherent in the combustion chamber. The diverted air flows through the plenum and enters the chamber about the edges of the protective sheet.

Kiln for waste disposal

Process and apparatus for heating a gaseous mixture from a nuclear reactor containing hydrogen and air to its ignition temperature to convert hydrogen to water vapor and then cooling the resultant gaseous mixture after heating to a temperature below its ignition temperature prior to discharging the resultant gaseous mixture from the apparatus.

Slab-shaped high efficiency catalytic reformer configurations particularly useful for generation of fuels to be used in fuel cell based generation systems. A plurality of structures forming a generally rectangular peripheral envelope are spaced about one another to form annular regions, an interior annular region containing a catalytic bed and being regeneratively heated on one side by a hot combustion gas and on the other side by the gaseous products of the reformation. An integrally mounted combustor is cooled by impingement of incoming oxidant.

A pulsed coolant thermocouple temperature measuring system is arranged to measure temperature above a limit operating temperature of the thermocouple includes a rake which is disposed across a hot gas path combustion turbine. Multiple thermocouple are disposed in respective channels in the rake to sense the temperature of hot gas from surplus which enter the thermocouple channels through respective sampling ports in the rake. The sample gas flows merge with a common channel and exhaust through a hot gas sample valve. When any of the thermocouples reaches a limit temperature, a coolant valve is opened as the hot gas valve is closed so as to drive coolant air into the common channel over the thermocouple through the thermocouple channels and the sampling ports into the hot gas path. A microcomputer receives and records the thermocouple signals and generates control signals to sequence the coolant and gas sample valves on and off as a function of the thermocouple temperature signals so the system is cycled through successive temperature reading periods without exceeding a predetermined temperature limit of the thermocouples. The microcomputer extrapolates the actual gas temperature as the endpoint temperature computed by a fast integrating method from the recorded thermocouple readings.
