Various biomass reactors systems and methods of pyrolyzing biomass are disclosed. One type of biomass reactor system comprises a plurality of biomass processing stations configured in series, each station comprising an auger reactor including an auger inlet for receiving biomass and a transfer screw for conveying the biomass through the auger reactor.

Disclosed is a biomass gasification and waste incineration integrated furnace, which relates to the technical field of biomass gasification and waste incineration, and includes a waste incineration furnace chamber and a biomass gasification furnace chamber. A mutual contact region exists between the waste incineration furnace chamber and the biomass gasification furnace chamber, and heat transfer can be realized between the waste incineration furnace chamber and the biomass gasification furnace chamber. Heat generated by the waste incineration furnace chamber is used for conduction to the biomass gasification furnace chamber, and excess heat generated by the waste incineration can be supplied to the biomass gasification furnace chamber for reactions therein, thereby reducing the heat additionally used by the biomass gasification furnace chamber and saving energy consumption.

An abatement apparatus and method are disclosed. The abatement apparatus is for treating an effluent stream from a semiconductor processing tool and comprises: a first abatement device configured to receive the effluent stream and operable to run in an active mode to treat the effluent stream; a second abatement device operable to run in an idle mode; and control logic operable, on receipt of an indication of an alarm condition associated with the first abatement device, to run the second abatement device in the active mode. In this way, a first or primary abatement device is provided which treats the effluent stream and a second or back-up abatement device is provided, should the first abatement device malfunction. However, by only causing the second abatement device to operate in the active mode when the first abatement device malfunctions, significant energy savings can be made.

In a method for physical and thermochemical treatment of biomass, the biomass moisture content is reduced in a dryer and ammonia (NH.sub.3) is also released from the biomass during drying. The dried biomass is then either pyrolyzed in a pyrolysis reactor and the pyrolysis gas is forwarded to and combusted in a combustion device to form flue gas, or is combusted in a combustion facility unit to form flue gas. In either case the flue gas is fed to a mixer. Oxygen (O.sub.2) is metered to the flue gas in the mixer and is fed directly to the dryer as drying gas. As the drying gas passes through the dryer, the sulfur dioxide (SO.sub.2) contained in the drying gas and/or the sulfur trioxide (SO.sub.3) chemically reacts with the ammonia (NH.sub.3) to form ammonium sulfite ((NH.sub.4).sub.2SO.sub.3) and/or ammonium sulfate ((NH.sub.4).sub.2SO.sub.4). Also a treatment facility physically and thermochemically treats the biomass.
