The following brief overview of the use of fluidized bed furnace issues should be noted: 1, into the furnace of coal particle size is controlled to meet the requirements of boiling boiling furnace, should control the particle size of coal into the furnace at about 3 mm, the maximum does not exceed 8 mm. 2, the rational use of wind, diligent operation to prevent coking operator must go through rigorous training, do not recognize the color of the flame to determine the temperature of the furnace, be targeted to improve the thermal efficiency of the roaster adjustment in order to ensure the normal firing furnace. 3, production organization, stove operation greater impact on coal consumption. Coal consumption not only by the level of exit gas temperature, thermal insulation system to reduce heat loss, degree burn coal, but also to the organization of production, stove operation related. The latter is easy to ignore, and some manufacturers capacity of small, often intermittent production roaster, bake a class stop a few days, often put out the furnace, the furnace resulting in raw coal consumption is high; some manufacturers operating on the stove grasp to no avail, to different furnace type (roaster, spray stove, oil furnace, etc.) using different methods of coal-fired fluidized bed furnace requirements, get the point, try closing the furnace operations, improve burn rate of coal, reducing air leakage. So who knows what the main factors affecting the boiling process is it a long time, about the coal combustion process is generally considered:? Fuel is to be heated and dried, and then precipitate volatile decomposition, if there is enough temperature furnace and oxygen, the volatile ignited a flame, blocking oxygen to the coke surface, hindering the coke combustion. While ensuring a heated domestic advanced boiling furnace coke, when it is close to burnout, oxygen reaches the surface Coke, Coke began to burn immediately. However, the combustion of fuel boiling in the furnace with the above-described process is different. Due to the amount of oxygen furnace and heated boiling faster, volatile cleavage reaction rate dramatically accelerate rapidly, forming a fuel to heat up, leading to volatile fuel and combustion can be simultaneously achieve higher temperatures and heat concentration. In boiling furnace combustion process, the volatiles and moisture mainly affect the combustion speed. Especially in the ignition, the first fuel to be heated and evaporated to remove moisture; when the fuel moisture is generally from 15% to 18% to 22% to 26% by weight of the load of the furnace cross-section per unit time will be from 1250 ~ 1315 Kgf · - 2 m · 1h? reduced to 750 ~ 890Kgf · -2 m · 1h ?, the same time, the central area of ??the furnace combustion intensity will be reduced, so that the average temperature is lowered from 985 ~ 1020 ℃ to 628 ~ 705 ℃, resulting in the combustion process The reduced stability. In particular, when all burning low calorific value or low quality coal gangue, its combustion efficiency depends mainly on the extent of burning embers carbon content. Ash content increases so can reduce the amount of fuel burned in the furnace, and causes mechanical ash increased about 6% to 18% of incomplete combustion heat loss.
