A combustion system which comprises a combustion chamber (1) wherein the supply of air is intercepted and a fluid (L) formed by mixing combustibles with water is supplied, water in the fluid (L) is thermally decomposed, combustibles are burnt, and a gas after combustion is discharged, a fluid storage tank (40) for storing the fluid (L) formed by mixing combustibles with water, a fluid supply section (50) for supplying the fluid (L) in the fluid storage tank (40) to the combustion chamber (1), and a gas recovery section (60) for recovering a gas discharged from the combustion chamber (1). The above combustion system inhibits the formation of nitrogen oxides, since the system is almost free from the contamination of nitrogen in air, and produces an exhaust gas containing hydrogen and carbon dioxide as main components, which results in the production of a clean exhaust gas and east recovery of an exhaust gas.

A method for improving the efficiency of power generation in a method for power generation comprising forcefully forming an ascending gas flow channel and a descending gas flow channel within a closed zone with a gas sealed therein, generating a whirling flow by the synergistic interaction of both and rotating a turbine by the whirling flow to generate electric power as well as a device for realizing the same. A whirling flow to rotate fans (3,4) is generated by installing a cylindrical rotor (2) between the ascending gas flow channel and the descending gas flow channel. Optionally, a second cylindrical rotor (12) is further installed between the ascending gas flow channel and the partition wall isolating the closed zone from outside so as to reduce the friction between the ascending gas flow and the descending gas flow. And, the present invention is suitable as a method for power generation by utilizing, for example, a temperature difference occurring in nature.

Front and rear side flange portions of a filter accommodating cylinder are provided with positioning pins. A flange portion of an upstream cylinder is provided with a notched groove and a flange portion of a downstream cylinder is provided with a notched groove. In consequence, when the filter accommodating cylinder is connected between the upstream cylinder and the downstream cylinder, each of the positioning pins disposed at the front and rear flange portions is engaged with each notched groove of the upstream cylinder and the downstream cylinder. The filter accommodating cylinder can be positioned to be coaxial with the upstream cylinder and the downstream cylinder. As a result, after performing a cleaning operation to a DPF, an operation of once again connecting the filter accommodating cylinder between the upstream cylinder and the downstream cylinder can be quickly and easily performed.

Disclosed is an exhaust assembly for a construction machine having a revolving upperstructure and an engine mounted on the revolving upperstructure. The exhaust assembly is to be arranged inside the revolving upperstructure of the construction machine, and is provided with an after-treatment device for exhaust gas from the engine and an exhaust pipe for releasing exhaust gas, which has been guided from an outlet port of the after-treatment device, to an outside. The exhaust assembly includes a concave-convex part, which has plural concavities and convexities, is arranged on an inner wall of the exhaust pipe, and extends in a direction of discharge of the exhaust gas.

An engaging groove (47) with which a gasket (42) is engaged is provided in each of a front side projecting portion (44) and a rear side projecting portion (46) formed in a filter accommodating cylinder (37) to be positioned on an outer peripheral surface (44A, 46A) of each projecting portion (44, 46). Therefore, when the gasket (42) latches on each of the projecting portion (44; 46) to be fitted thereon from an outside, the gasket (42) can be engaged with the engaging groove (47) provided in each of the projecting portions (44, 46). In consequence, at the time of mounting and removing the filter accommodating cylinder (37), the falling-off of the gasket (42) can be prevented, and, for example, an inspection operation, a cleaning operation and the like of an accommodated particulate matter removing filter (41) can be easily performed.

In a microcomputer equipped with a built-in temperature sensor, diodes as a temperature sensor are incorporated in a pair of circuit blocks, respectively, and placed in opposite polarity connection to each other. When detecting a temperature of the microcomputer, a constant current If is supplied to the diodes through terminals commonly connected to both the diodes. A voltage Vf generated at each diode is read through terminals located at more adjacent nodes to the diode when compared in position with the terminals.
