    摘要: A fast pyrolysis heat exchanger system and method for economically and efficiently converting biomass and other combustible materials into bio-oil. The system employs multiple closed loop tubes situated inside the heat exchanger. As heat carrier is deposited at the top of the heat exchanger and caused to move downwardly therethrough, heat is transferred from the tubes to the heat carrier which is then transferred to a reactor where it is placed in contact with the combustible materials. Vapor containing char fines is discharged from the reactor into a vacuum-operated blow back filter. The blow back filter is activated when a drop in vacuum level at the output of the reactor is detected. Thereby, excess char buildup on the blow back filter elements is removed.

    摘要: Disclosed is a vertical pyrolysis equipment for coal material, which comprises an enclosed kiln body with an inlet and an outlet, a flame-gas heating pipelines provided inside the kiln body, coal material propulsion and pyrolysis passage formed between the flame-gas heating pipelines and inner wall of the kiln body, coal pyrolysis gas collecting tube communicated with the coal material propulsion and pyrolysis passage provided on the kiln. The heat generated by flame-gas heating pipelines is conducted and radiated to coal powder in the coal material propulsion and pyrolysis passage. The coal powder sufficiently absorbs the heat and is pyrolyzed into fuel gas, tar gas and coal with high heat value inside the coal material propulsion and pyrolysis passage. The pyrolyzed fuel gas and tar gas are transferred to the gas dedusting-liquifying mechanism outside the kiln through the connecting coal pyrolysis gas collecting tube for collecting, dedusting, separating and high-pressure liquefying.

    摘要: The invention relates to a process for keeping coke oven chambers hot during the stoppage of a waste heat boiler, wherein the coke oven chambers are kept hot during the stoppage after emptying using externally heated burners, as a result of which a flue gas low in pollutants is obtained from said burners, such that the waste heat boilers which, during normal operation, cool the flue gases from the coke oven benches and use said gases to produce steam can be shut off and overhauled, and a flue gas low in pollutants which can be dissipated directly into the atmosphere is obtained by the burner operation. The invention also relates to an apparatus for keeping coke oven chambers hot, said apparatus comprising in particular a coke oven chamber bench, a flue gas collection line, a flue gas chimney, a waste heat boiler, a waste gas collection line and a waste gas purification system, wherein the flue gas chimney and the waste heat boiler can be shut off on the flue gas side and on the waste gas side.

    摘要: The pressure in the coking chamber of a coke oven is held at about atmospheric pressure, and the temperatures at the opposite longitudinal ends of the combustion chamber are independently controlled. Fuel gas is supplied to hold the temperature at the opposite longitudinal ends to be at least about 1000.degree. C. separately from a main burner for the combustion chamber, and the pressure in the coking chamber during the first part of coking is kept in a range from 5 mmH.sub.2 O below atmospheric to 10 mmH.sub.2 O above atmospheric pressure. This allows efficient coke production even with low moisture content coking coal, and coal crumbling near the oven doors is not a problem. The process is typically carried out in a coke oven having a pressure control system for each coking chamber including plural piping devices for supplying a pressure fluid and switching valves for selectively applying the pressure fluid to the nozzle in the rising pipe through any selected one of the piping systems. The fluid pressure applied to the nozzle and the pressure in the coking chamber are preferably changed over time based calculated relationships between carbonization time, coking chamber pressure, and fluid pressure applied to the nozzle.

    摘要: The endpoint of devolatilization of a coal mass in a coke oven during a coking cycle is determined by providing a probe which is capable of supplying an electrical signal which indicates the effective thickness of a layer of carbon deposited on the probe by gas released from the coal mass and in addition indicates the rate of devolatilization of the coal mass which is a measure of the heat input to the coal mass and can be used to control heat input to the coke oven.
