Straw granulator is based on crop straw as raw material, through the pressure of the machine, straw is compressed into granular clean fuel. The problem of straw can be processed and processed in rural areas, and the problem can be solved by mixing straw into feed in rural areas.
So what are the combustion methods of straw pellets? Let's introduce it to you.
1、 Stratified combustion
层状燃烧又称火床燃烧, 仅适用于固体燃料, 是小型锅炉的主要燃烧方式。
Laminar combustion, also known as fire bed combustion, is only suitable for solid fuel and is the main combustion mode of small boilers.
Laminar combustion has a wide range of adaptability, but the mixture of air and combustor is not good, combustion reaction is slow, and sometimes black smoke appears.
2、 Suspension combustion
悬浮燃烧又称火室燃烧, 适用于固体、液体或气体燃料，是大中型锅炉的主要燃烧方法。悬浮燃烧不用炉排, 燃料与空气接触面积大, 着火迅速, 燃尽率高, 燃烧效率和锅炉热效率高,可实现自动控制。但设备多,系统复杂,能耗大。
Suspension combustion, also known as fire chamber combustion, is suitable for solid, liquid or gas fuel, and is the main combustion method of large and medium-sized boilers. Suspension combustion does not use grate, the contact area between fuel and air is large, the ignition is rapid, the burn out rate is high, the combustion efficiency and boiler thermal efficiency are high, and the automatic control can be realized. But there are many equipments, complex system and high energy consumption.
3、 Boiling combustion
燃烧物被粉碎成小于2mm 的颗粒后送入炉膛, 空气从布风板上的风帽进入, 使煤上下翻滚, 呈类似液体沸腾状态燃烧。沸腾燃烧设备的蓄热量大, 燃烧反应强烈。这种方式燃烧温度在900 度以下, 可大大减少严重致癌物质氮氧化物的生成, 并可方便地采取脱硫措施, 而利于环境保护, 故大有发展前途。
After being crushed into particles less than 2 mm, the combustor is sent into the furnace, and air enters from the air cap on the air distributor, which makes the coal roll up and down, burning in a similar state of liquid boiling. Boiling combustion equipment has large heat storage capacity and strong combustion reaction. This method of desulphurizing can greatly reduce the temperature of combustion of this carcinogenic substance below 900 degrees, which is conducive to the development of such a carcinogenic substance.
The above is about the straw granulator pellet fuel three kinds of combustion way, hoped can help everybody.
