    如何快速的提高生物质热风炉的燃烧效率呢?

    提到生物质热风炉,不得不说热风炉的燃烧效率,燃烧效率是提高热风炉燃烧的一个重要途径,只有燃烧效率高的热风炉,才能提高热风炉的工作效率,降低损失,那么如何快速的提高生物质热风炉的燃烧效率呢?生物质热风炉总体优势:热效高、低能耗,不仅仅是热风炉本体,底座、炉膛的设计,更有助于的二次给风的设计与布局以及热风炉炉排成份元素的对比等等优势!

    When referring to biomass hot-blast stove, we have to say that combustion efficiency of hot-blast stove is an important way to improve combustion of hot-blast stove. Only high combustion efficiency hot-blast stove can improve the working efficiency of hot-blast stove and reduce losses. So how to quickly improve the combustion efficiency of biomass hot-blast stove? Overall advantages: high thermal efficiency and low energy consumption, not only the design of the main body, base and hearth of the hot stove, but also the design and layout of secondary air supply and the comparison of elements of the hot stove grate.

    ??1、充足的氧气:如果过量空气系数过小,即空气量供应不足,会使燃烧效率降低;如果过量空气系数过大,则会降低炉膛温度,增加不完全燃烧热损失。最佳的过量空气系数使q2 q3 q4之和为最小值。

    Adequate oxygen: If the excess air coefficient is too small, that is, insufficient air supply, the combustion efficiency will be reduced; if the excess air coefficient is too large, the furnace temperature will be reduced and the incomplete combustion heat loss will be increased. The optimum excess air coefficient minimizes the sum of Q2 Q3 q4.

    ??2、采用防垢、除垢技术:通过采用生物质供暖热风炉除垢剂和电子防垢器,优化水汽循环系统,合理控制热风炉的排污率,从而减少水垢,提高热风炉热效率。

    _2. Scale prevention and descaling technology: By using biomass heating hot stove descaling agent and electronic scale preventer, the water vapor circulation system is optimized, and the fouling rate of hot stove is reasonably controlled, so as to reduce scale and improve the thermal efficiency of hot stove.

    ??3、保持生物质供暖热风炉燃料合理的火焰前沿位置,火焰前沿应该位于高端炉排与中部炉排的之间区域,火焰在炉排上的充满度好。

    _3. Maintain the reasonable flame front position of biomass heating hot-blast stove fuel. The flame front should be located between the high-end grate and the central grate, and the flame filling degree on the grate is good.

    Advantages of Dacheng Biomass Hot Stove in Hengyang

    一、热风炉自动化程度高:

    1. High degree of automation of hot blast stoves:

    热风炉操作控制采用PLC电控操作,热风炉送料、出渣、炉膛温度、炉排调速,引风、鼓风都采用变频及自动控制,系统设置了一套手动操控装置,以备调试、维修及系统计算机出现故障使用,而水泵更是设置了一套常规继电接触器控制装置,确保热风炉任何情况下都能可靠自动给水。

    The operation and control of hot blast stove are controlled by PLC. Feeding, slag discharging, furnace temperature, grate speed regulation, frequency conversion and automatic control are used for induction and blast. A set of manual control device is set up in the system for debugging, maintenance and computer malfunction, and a set of conventional relay connection is set up for water pump. Touch control device ensures reliable automatic water supply for hot blast stove under any circumstances.

    二、热风炉热效率高:

    2. The thermal efficiency of hot blast stove is high:

    热风炉设计注重高热效,低能耗。热风炉设计热效率均大于百分之八十四,这点从我们产品实际案例中得到检验,我司保证颗粒热值≥4000颗粒,毎吨颗粒产汽量≥5吨。

    Hot blast stove design pays attention to high thermal efficiency and low energy consumption. The design thermal efficiency of hot blast stoves is more than 84%, which is verified by the actual cases of our products. Our company guarantees that the calorific value of particles is more than 4000 grains, and the steam output of grains is more than 5 tons per ton.

    三、热风炉全封闲式给料系统:

    3. Full-sealed idle feeding system of hot blast stove:

    生物质热风炉给料系统打破常规其它热风炉的给料方式,我司生物质热风炉给料系统均采用螺旋给料机构送料装置,即封闲式送料。全套给料系统由料仓、给料螺旋构、电机、布袋组成。

    The feeding system of biomass hot-blast stove breaks the conventional feeding mode of other hot-blast stoves. The feeding system of biomass hot-blast stove in our company adopts spiral feeding mechanism, i.e. closed and idle feeding. The whole feeding system consists of silo, feeding screw, motor and cloth bag.

    其送料的优点:在于分料过程采用全自动控制螺放给料机构,通过螺旋给料机把生物质颗粒、生物质压块推进热风炉炉膛。打破了其它生物质厂家传统的“用上煤机把料送入加煤斗”式给料方式。螺旋给料机方便安全,使用寿命长。且多种型号生物质燃料送料机构适合不同的炉型的给料。螺旋给料机杜绝了传统煤斗式加料回火的问题。

    The advantages of the feeding system are that the automatic screw feeding mechanism is used in the feeding process, and biomass particles and biomass compacts are pushed into the hot blast stove through the screw feeder. It breaks the traditional feeding mode of "feeding material into coal hopper with coal feeder" of other biomass manufacturers. The screw feeder is convenient, safe and has a long service life. Moreover, various types of biomass fuel feeding mechanism are suitable for feeding of different furnace types. The screw feeder eliminates the problem of traditional coal hopper feeding and tempering.

    四:热风炉二次给风设计与布局优势:

    Fourth, the design and layout advantages of secondary air supply for hot blast stoves:

    众所周知,生物质热风炉与燃煤热风炉、柴炉的最大区别是增加了二次给风,然而二次风管风向如何布局?则是生物质热风炉的重中之重,布局好了,则让二次风向优势提高了炉膛助燃的效果,二次风布局好了也是热风炉燃料低能耗的帮助。相反仅仅是在炉膛中加几条二次风管则可能是造成烧坏炉排、烧坏炉墙、烧坏底座钢架的杀手。

    As we all know, the biggest difference between biomass hot-blast stove and coal-fired hot-blast stove and firewood stove is the increase of secondary air supply. However, how to arrange the wind direction of secondary air duct? It is the most important part of biomass hot blast stove. If the layout is good, the secondary air direction advantage will improve the combustion supporting effect of the furnace. A better secondary air distribution is also the help of low energy consumption of hot blast stove fuel. On the contrary, just adding a few secondary air ducts in the furnace may be the killer of burning the grate, the wall and the steel frame of the base.
