Heat-conduction oil furnace of horizontal circulating fluidized bed

Abstract

The invention discloses a heat-conduction oil furnace of a horizontal circulating fluidized bed, and relaters to combustion equipment of the circulating fluidized bed for inferior coal, solid wastes, urban and industrial sludge and biomass fuels, in particular to a heat-conduction oil heating device. The heat-conduction oil furnace is mainly composed of a feeding device, a main combustion chamber, an auxiliary combustion chamber, an after-combustion chamber and a cyclone separator, wherein heat-conduction oil coils are arranged in the main combustion chamber and the after-combustion chamber, an economizer and an air pre-heater can be arranged behind the cyclone separator, and a waste heat boiler can also be arranged behind the cyclone separator. The heat-conduction oil heating device adopts a horizontal circulating fluidized bed technology, changes the traditional structural style adopting a chain grate furnace to heat, changes the single-stage and vertical circulating structure of the traditional fluidized bed boiler, effectively reduces the height of the boiler, and reduces the requirement on the construction height of plants. Through reasonable structural layout, the problem that the circulating fluidized bed boiler is easily abraded is effectively solved, and the heat-conduction oil heating device has wide adaptability to fuels, has high combustion efficiency, and has lower pollutant discharging quantity.

Description

technical field [0001] The invention relates to a heat-conducting oil furnace, in particular to a heat-conducting oil furnace adopting horizontal circulating fluidized bed technology. Background technique [0002] Heat-conducting oil furnace is a new type of special boiler with heat-transfer fluid as the heating medium, which has low-pressure and high-temperature working characteristics. Although the working pressure of the organic heat carrier furnace is relatively low, the temperature of the heat transfer fluid in the furnace is high, and most of them are flammable and explosive. Once leakage occurs during operation, it will cause fire, explosion and other accidents, and even cause casualties and property loss. Therefore, the general requirement for organic heat carrier furnaces is high energy efficiency under the premise of ensuring safety. Due to the wear and tear of the heating surface during the operation of circulating fluidized bed boilers in the past, circulating f...
