Combined steam and gas turbine engine with magnetic transmission

In a combined steam and gas turbine engine cycle, a combustion chamber is made durable against high pressure and enlarged in length to increase the operation pressure ratio, without exceeding the heat durability temperature of the system while increasing the fuel combustion gas mass flow four times as much as the conventional turbine system and simultaneously for greatly raising the thermal efficiency of the system and specific power of the combined steam and gas turbine engine.Water pipes and steam pipes are arranged inside the combustion chamber so that the combustion chamber can function as a heat exchanger and thereby convert most of the combustion thermal energy into super-critical steam energy for driving a steam turbine and subsequently raising the operation pressure ratio and the thermal efficiencies of the steam turbine cycle and gas turbine cycle. The combustion gas mass flow can be also increased by four times as much as the conventional turbine system (up to the theoretical air to fuel ratio) and the thermal efficiency and the specific power of the gas turbine cycle are considerably increased.Further, the thermal efficiency of the combined system is improved by installing a magnetic friction power transmission system to transmit the power of the system to outer loads.

Honeycomb filter for exhaust gas decontamination, adhesive, coating material and process for producing honeycomb filter for exhaust gas decontamination

An object of the present invention is to provide a honeycomb filter for purifying exhaust gases which makes it possible to alleviate a thermal stress generated due to occurrence of a local temperature change and which is less likely to generate cracks and superior in strength and durability, an adhesive that has a low thermal capacity and is capable of alleviating the thermal stress, a coating material that has a low thermal capacity with a superior heat insulating property and is capable of alleviating the thermal stress, and a manufacturing method of the honeycomb filter for purifying exhaust gases that can improve precision in the outside dimension, and reduce damages in the manufacturing processes.
The present invention relates to a honeycomb filter for purifying exhaust gases, having a structure in that a plurality of column-shaped porous ceramic members, each having a number of through holes that are placed side by side in the length direction with partition wall interposed therebetween, are combined with one another through adhesive layers so that the partition wall that separate the through holes are allowed to function as a filter for collecting particulates, and in this structure, the thermal expansion coefficient αL of the adhesive layer and the thermal expansion coefficient αF of the porous ceramic member are designed to have the following relationship:
0.01<|αL−αF|/αF<1.0.
