The main factors affecting the boiling furnace combustion analysis of the impact of many factors boiling furnace combustion, such as coal-burning properties, coal particle size distribution, flow of quality, the way to the coal bed temperature, bed structure and operation level and so on. Structural properties of coal, volatile content, calorific value, ash melting point of boiling burning stove will impact. For a high volatile content, structure relatively soft bituminous coal, lignite and oil shale and other fuels, when entering the fluidized bed coal by pyrolysis, the first precipitation volatile, coal particles become loose porous structure, oxygen surrounding the particle small internal combustion product diffusion and outward diffusion resistance, can improve the combustion rate. For less volatile content, the structure of dense anthracite, coal, etc., when coal by pyrolysis, the molecular bond is not easy to break, easy to precipitate internal volatile oxygen around the difficult selection to the particle diffusion roaster internal combustion rate decreases. Volatile analyzed, after the formation of the burning coal particle surface layer of hard gray shell, hampering the outward diffusion of combustion products and inward diffusion of oxygen. Not the coke burning fuels, yet some form of powder coke burn is likely to be out of the furnace, fired back if no separation boiling mud oven drying, fly ash carbon content increases, the increase is not safe combustion loss . When designing a lower calorific value coal furnace, the furnace may be due to the low temperatures and dense phase impact on combustion. When the low calorific value of coal, ash and its conversion will increase the conversion of water per kg of fuel out of the dense phase region enthalpy increases, the dense phase exothermic and endothermic fuel may lose balance. Different fuels have different ash melting point, depending on the composition of the ash. There are four main components of the ash: AL2O3, SiO2, ΣFeO and CaO. When the temperature reaches the softening temperature of the ash, the ash begins sticky. In the fluidized bed, very sensitive to the slagging; fluidized bed after slagging difficult to maintain a normal fluidized state, but can not guarantee efficient combustion in the furnace fired roaster slime Which is good, eventually leading to forced shutdown. So when designing coal ash melting point to grasp. Boiling heat stable combustion furnace; energy efficient and clean burning fuel, burn rate of 99%. By collecting large bag pulse dust collector, flue gas clean clouds, Ringelman index up more than one level; Sulfur furnace can more than 80%, low-temperature combustion NOX survive less; strong fuel adaptability, stable combustion of high volatile, low ash, heat in a 2000 kcal / kg or more kinds of coal.
