Description

一种正反烧结合燃煤炉具A kind of forward and reverse combustion combined coal-fired stove

技术领域technical field

本实用新型涉及炊事炉具领域,特别是涉及一种正反烧结合燃煤炉具。The utility model relates to the field of cooking stoves, in particular to a coal-fired stove combined with forward and reverse combustion.

背景技术Background technique

在我国农村和城郊地区,仍有大量家庭采用相对分散的燃煤供热方式,不仅效率低、污染严重,而且对环境的影响数倍于其燃料消耗所占的比例。目前我国每年消费大量煤炭,其中民用部分基本上全部为分散式焚烧,没有采取除尘、脱硫等环保措施,散煤燃烧排放的污染物量是火电燃煤排放的5至10倍。In my country's rural and suburban areas, there are still a large number of households that use relatively scattered coal-fired heating methods, which are not only inefficient and polluting, but also have an impact on the environment several times the proportion of their fuel consumption. At present, my country consumes a large amount of coal every year, of which the civil part is basically all incinerated in a decentralized manner, and no environmental protection measures such as dust removal and desulfurization are taken.

家用燃煤炉具的燃烧过程具有周期性,燃烧初期容易空气不足,煤热解气化产生的煤气不能充分燃烧,大量毒害和可燃成分随烟气排放,造成环境污染和能量损失;燃烧后期煤层减薄,过量的空气又会降低炉温和传热效率,并增大排烟热损失。部分炉型仅通过高温富氧的方式来提高煤的燃烧效率,但却会加大氮氧化物(NOx)排放。另外,提高燃烧温度还会增大脱硫逆反应,降低炉内脱硫效率。The combustion process of household coal-fired stoves is cyclical. In the early stage of combustion, air is easily insufficient, and the gas produced by coal pyrolysis and gasification cannot be fully burned, and a large number of toxic and combustible components are discharged with the flue gas, causing environmental pollution and energy loss; the coal seam in the later stage of combustion Thinning, excess air will reduce furnace temperature and heat transfer efficiency and increase exhaust heat loss. Some furnace types only improve the combustion efficiency of coal by means of high temperature oxygen enrichment, but will increase the emission of nitrogen oxides (NOx). In addition, increasing the combustion temperature will also increase the reverse reaction of desulfurization and reduce the desulfurization efficiency in the furnace.

现有的炉具分为两种类型,分为正烧式的反烧式的,其中正烧最普遍的直燃方式。固体燃料燃烧时,火焰顺热烟气自然流动方向传播,优点是燃烧强度高,火力旺,能满足用户炊事需求,缺点是挥发份析出速度快,容易产生黑烟,适用于无烟煤等挥发份低的燃料。反烧固体燃料燃烧时,火焰逆热烟气自然流动方向传播,优点是能延缓挥发分析出速度的特点,炉温高、燃烧充分,可基本消除黑烟,颗粒物排放浓度低,缺点是燃烧强度低,火力较弱,不宜用于炊事,适用于烟煤等挥发份高的燃料。Existing stoves are divided into two types, which are positive-firing and reverse-firing, among which positive-firing is the most common direct-firing method. When the solid fuel burns, the flame spreads along the natural flow direction of the hot flue gas. The advantage is that the combustion intensity is high and the firepower is strong, which can meet the cooking needs of users. of fuel. When the anti-burning solid fuel is burned, the flame spreads against the natural flow direction of the hot flue gas. The advantage is that it can delay the speed of volatilization analysis. The furnace temperature is high and the combustion is sufficient, which can basically eliminate black smoke. Low, weak firepower, not suitable for cooking, suitable for high volatile fuel such as bituminous coal.

目前,家用燃煤炉具大都使用普通正烧原理,空气从炉具底部进入,通过整个炉膛,其燃烧过程具有周期性,燃烧初期容易空气不足,煤热解气化产生的煤气不能充分燃烧,大量毒害和可燃成分随烟气排放,造成环境污染和能量损失;燃烧后期煤层减薄,过量的空气又会降低炉温和传热效率,并增大排烟热损失。At present, most household coal-fired stoves use the common burning principle. Air enters from the bottom of the stove and passes through the entire furnace. The combustion process is periodic. At the initial stage of combustion, air is easily insufficient, and the gas produced by coal pyrolysis and gasification cannot be fully burned. A large number of toxic and combustible components are discharged with the flue gas, causing environmental pollution and energy loss; the coal seam is thinned in the later stage of combustion, and the excess air will reduce the furnace temperature and heat transfer efficiency, and increase the heat loss of exhaust gas.

因此,如何提供一种能够克服上述缺陷的燃煤炉具是本领域技术人员目前需要解决的技术问题。Therefore, how to provide a coal-fired stove that can overcome the above-mentioned defects is a technical problem that those skilled in the art need to solve at present.
