摘要:
The invention provides a burner array for a reduction reactor 100, wherein the burner array includes multiple burners 200 disposed on a wall 101 of the reduction reactor to allow an inner temperature in the reduction reactor 100 to reach above 1200°C, wherein the reduction reactor 100 has a reaction space formed therein, wherein each burner has a fuel feeding hole 210 and multiple oxygen feeding holes 220 formed therein, wherein each burner 200 has a head portion 201 thereof having an elongate combustion space 202 formed at one end thereof, the combustion space fluid-communicating with the reaction space of the reactor, wherein the elongate combustion space has a length such that oxygen supplied from the oxygen feeding holes thereto is completely consumed via oxidation or combustion with fuels supplied from the fuel feeding hole thereto only in the elongate combustion space upon igniting the burner, wherein non-combusted fuels and H 2 O molecules and/or CO 2 molecules generated via the oxidation reaction in the elongate combustion space are flowed into the reaction space of the reduction reactor, where only a reduction reaction of the H 2 O molecules and/or CO 2 molecules occur at the temperature above 1200°C using a radiation heat generated from the burner. Further, the invention provides a synthesis gas recycling system comprising: the burner array for the reduction reactor as defined above; a cooling and compressing module 400 configured to cool and compress the synthesis gas collected via a gas collection line 121 from the synthesis gas outlet 120; a storage tank 500 configured to receive and store the cooled and compressed gas from the cooling and compressing module 400, and to supply the stored gas to the burner array 200, thereby to allow synthesis gas recycling; and an oxygen generator 600 configured to generate oxygen and supply the oxygen to the oxygen feeding holes 220.

The present invention may be embodied as a biofuel heating system for converting biofuel to heat energy to be delivered to a load comprising a combustion chamber defining a combustion zone, an under-fire zone, and an over-fire zone. A controller operates at least one of a fan, an under-fire damper, and an over-fire damper based on at least one operating parameter such that air flows along a flow path extending from at least one of an under-fire port and an over-fire port, through the combustion chamber, through a burn-out port, through a burn-out chamber, through a heat exchange port, through a heat exchange chamber, and out of an exhaust port. The heat exchange system transfers heat energy from air flowing through the heat exchange chamber to the working fluid.

This method for inhibiting the occurrence of a pyrolysis deposit in a pyrolysis gasification system includes: gasifying biomass (S2) through pyrolysis in a pyrolysis gasification furnace (5); separating, in a solid-gas separation unit (7), a pyrolysis gas (G1) and a carbide (C) continuously formed through pyrolysis of the biomass (S2); feeding an oxygen-containing gas (G3) to the separated pyrolysis gas (G1); and introducing the pyrolysis gas (G1) together with the oxygen-containing gas (G3) to a combustion furnace (6) through a pipe (9) which constitutes a pyrolysis gas line (8).

There is described a plant for reducing bitumen fumes comprising: a) an intake system for drawing in the bitumen fumes and mixing those fumes with external air (ambient air) to produce an admixture of external air/bitumen fumes; b) a system for introducing this admixture into a boiler (9) as a primary supply (primary air) so as to maintain the admixture in the boiler (9) for at least two seconds; c) a sensor which is for measuring oxygen and which is positioned in the discharge chimney of the burnt materials and which is capable of adjusting the proportion between the external air and the bitumen fumes in the admixture. The main advantage of the described plant is the reduction of the pollutants in the fumes discharged from the chimney of the installation to a level below the levels imposed by the standard.

Method of operating a long direct-fired inclined counterflow rotary kiln for the thermal treatment of material and counterflow rotary kiln adapted for same, whereby material to be treated is introduced into the kiln at the inlet end (2) and treated material is evacuated from the kiln at the outlet end (1), whereby a main combustion zone (6) extends over a distance of ¼ to 1/3 of the internal length L int of the kiln, whereby a supplementary combustion zone (5) extends over a distance from the inlet end (2) of at most ¼ of the internal length L int , and whereby no combustion takes place in a heat exchange zone (7) located between the main combustion zone (6) and the supplementary combustion zone (8).
摘要:
Provided is an optimum-operation control system, for a sludge-processing apparatus 1 incinerating a sludge of which sludge energy is adjusted by a moisture-reducing equipment 10 by a thermal operation equipment 20, including a an optimum-operation control apparatus 30 including a relation-maintaining section maintaining a correlation between a plurality of energy-consuming elements for a plurality of elements relating to moisture reduction and a thermal operation of the sludge and the sludge energy and a correlation between a total energy consumption amount of each energy-consuming element and the sludge energy. The optimum-operation control apparatus 30 measures the current energy-consuming elements and controls a power consumption amount of a dehydrator 11 to be increased and decreased so that the obtained total energy consumption amounts are minimized at a sludge energy value based on the correlation.
