Provided herein is a process for improving the heating value of a cellulosic waste material. The process includes the steps of treating the cellulosic waste material with an acid solution, recovering heat produced by treating the cellulosic waste material, and filtering the treated cellulosic waste material to produce a filter cake. The disclosure also relates to a system for implementing the process.

An electric cigar lighter, such as used in a motor vehicle, has a bimetallic switch in the form of a snap disk positioned within a socket. When using commercial appliance plugs with such a snap disk, the diameter of the socket does not need to be enlarged compared to conventional sockets. Contact bounce and contact interruptions are prevented. These advantages are achieved by placing the contact disk and a contact part on an adjustment ring inserted with a sliding fit into a tubular member located within the socket. A control knob for the lighter fits into a plug sleeve within the socket. A spring spider on the control knob locks onto an annular bulge on the plug sleeve provides a pressure point for quickly switching the heating element to the on-position.

A conical or cylindrical burner for burning wood wastes, bark residues and other combustible solid wastes is disclosed which includes an insulating lining such as a refractory material applied over the inner surface of the shell of the burner to retard heat loss. The insulating liner may be applied in situ after erection of the burner shell. Rows of concentrically arranged grates provide means for delivering primary combustion air to the burning zone. The overfire and recirculation air system includes means to supply ambient and/or hot recirculating gases in a predetermined ratio to keep the burner temperature within a predetermined range. A temperature sensing means located near the exhaust opening at the top of the burner is operatively connected to a controller which automatically adjusts interconnected dampers in the ambient air and hot recirculating gas inlets of the overfire and recirculation air system to a ratio of ambient air to recirculated hot gases to maintain the burner temperature essentially constant even with variable fuel feed to the burner. The refuse burner is capable of combusting wood and bark residues efficiently with significantly reduced visible smoke and particulate matter.

A feed injector for a circulating fluid bed reactor is fitted with a discharge nozzle with a circular, radially notched discharge orifice to improve the surface-to-volume ratio of the spray pattern formed by the nozzle. The feed injector is useful for injecting fluids into various types of circulating fluid bed reactors in which good contact between the components of the fluidized bed and the injected fluid is required. It is particularly useful in fluid coking reactors.

The invention relates to a method for combusting an organic waste concentrate, which contains alkali metal compounds, under oxidative conditions for recovering the alkali metal compounds as alkali metal carbonates.According to the invention, the combustion is carried out at a temperature of at least about 850° C. The formed flue gases are cooled below a sticking temperature range of the alkali carbonates by mixing, and simultaneously water (8) is poured on the walls (9) of a cooling zone (2) at least at the sticking temperature range.

The heating stove system includes a fuel hopper (10) from which fuel is fed into a pyrolysis gasifier (12) by means of a fuel auger apparatus (14). Controlling the entry of biomass input and air into the gasifier and ignition of the material in the gasifier is a head valve apparatus (16) which includes an igniter (129). The gasifier (12) in operation produces carbon and fuel gas which are moved into a stove burner (90) by a blower apparatus (18). The operation of the heating stove system is automatically controlled from a thermostat (150).
摘要:
An instant cigar lighter comprising a holder adapted for mounting on an automobile dashboard, an elongate igniter plug receivable in the holder and having a spiral heating coil disposed at its inner end, a metal cup surrounding the heating coil and at one end connected thereto, and means for establishing an electrical circuit through the cup and heater coil to enable energization of the latter. The lighter is intended for use with a source of power having a higher voltage than the voltage rating of the coil, and has special heat responsive means comprising a bimetal disk engageable with the rim of the cup and closely juxtaposed to the heating coil for substantially instantly opening the circuit in response to heating of the coil to a useful predetermined temperature. The bimetal disk and the metal cup can cooperate to constitute a tightly closed enclosure closely surrounding the heating coil, the disk comprising one large wall of the enclosure whereby heat from the coil is immediately experienced by the disk to effect a very rapid response of the latter. The voltage rating of the heating coil can be one-half of the output voltage from the power source such that the coil becomes heated at a greatly increased rate and reaches a useful temperature in a period of less than several seconds, after which its circuit is opened to prevent burn-out.
