Provided is a vacuum pump that can realize energy conservation when performing abatement of exhaust gas.

A vacuum pump that sucks in and exhausts exhaust gas includes a motor serving as a drive source, and a first controller that controls driving of the motor. The first controller monitors a state of the motor, and in a case in which the state of the motor is a specific state excluding when starting up and when stopped, outputs a specific signal (process signal) to an external entity.

Plastic-powered power generator. In an embodiment, the plastic-powered power generator comprises a primary reactor with an air-fuel distribution assembly configured to supply fluidized polymer, air, and oxidizer to a primary reactor chamber, and an ignition system configured to ignite a mixture of the fluidized polymer, air, and oxidizer. The primary reactor chamber extends into a secondary reactor, to, when ignited, heat air flowing through the secondary reactor from a blower to a heat exchanger. The heated air flow may convert fluid, in a coil within the heat exchanger, into steam, which can drive a turbine to generate electrical power.

A process of making a fuel product from a non-combustible high protein organic material such as a biological by-product or waste material. The moisture content of the high protein organic material is mechanically reduced and dried to reduce the moisture content to less than ten percent (10%). The high protein organic material is pulverized to a particle size of less than about 2 mm. The high protein organic waste material is fed into a combustion chamber and separated during combustion such as by spraying high protein organic waste material within the combustion chamber. Temperature and combustion reactions within the combustion chamber are controlled by controlling the moisture in the combustion atmosphere and energy injections at or downstream of the combustion chamber. The concentration of protein thermal decomposition by-products, temperature, and residence time and/or additions of energy plasma within the combustion chamber environment are controlled to degrade hazardous polyfluoro compounds.

A biomass energy system utilizes an automated biomass distribution system for evenly distributing biomass within a furnace of the biomass energy system. The even distribution of biomass dramatically increases efficiency of the biomass energy system. The automated biomass distribution system includes a control unit, a set of I/P control boxes, and a set of valve assemblies. Each valve assembly includes a pneumatic actuator, a plug and a discharge duct matching the shape of the plug.

A cement kiln burner device includes a powdered-solid-fuel flow channel, a first air flow channel placed inside the powdered-solid-fuel flow channel to be adjacent to the powdered-solid-fuel flow channel, having means for swirling an air flow, an outer air flow-channel group placed concentrically in an outermost side outside the powdered-solid-fuel flow channel, having three or more second air flow channels adapted to form means for straightly forwarding an air flow, and a combustible-solid-waste flow channel placed inside the first air flow channel. The second air flow channels are placed proximally to each other in a radial direction within a range where air flows ejected from the respective second air flow channels are merged to form a single air flow, and are configured to control flow rates of the air flow ejected from the respective second air flow channels, independently for each second air flow channel.

This solid fuel burner is provided with: a venturi tube in which a channel for mixed fluid in a fuel nozzle narrows toward the center in the channel cross section; a fuel concentrator that imparts, to the mixed fluid, a velocity component away from the center of the fuel nozzle; and a channel separation member that separates the channel of the fuel nozzle into an internal side and an external side; wherein the channel separation member is shaped in such a way that the cross sectional area of an external channel is larger at the downstream end than at the upstream end, and the upstream end of the fuel concentrator is located between the upstream end and the downstream end of an expanded portion of the venturi tube. This solid fuel burner prevents solid fuel particles, which is ground biomass fuel, from adhering and depositing inside the nozzle.

The invention relates to a feeder and method for feeding raw material which comprises plastic to a gasification, pyrolysis or combustion furnace, in which the feeder comprises a screw feeder part and a pneumatic feeder part in order to form a combined feeder for feeding the raw material, the screw feeder part comprises at least a screw to transfer the raw material to the pneumatic feeder part and at least one cooling device to cool the raw material in the screw feeder part, and the pneumatic feeder part arranged after the screw feeder part comprises at least one inlet to supply pneumatic carrier material to the raw material in the pneumatic feeder part for forming a mixture of the raw material and pneumatic carrier material.
