Straw, as a common crop waste, has a variety of treatment methods, among which straw briquettes is the most common one. Taking straw briquettes as a fuel form can effectively solve the problems of straw treatment and energy utilization. However, in practical application, sometimes there will be insufficient combustion of straw briquettes. What is the reason?

First of all, we need to know the basic principle of straw briquette combustion. Straw briquettes combustion is to compress straw into blocks and use them as fuel for combustion. The density of compressed straw blocks is greatly increased, and higher temperature and longer combustion time can be obtained when burning, thus improving the utilization rate.

The main reasons for insufficient combustion of straw briquettes are as follows:

1. The quality of straw is not good. Different kinds and varieties of straw are different in chemical composition and physical properties, which will also lead to their different characteristics in the combustion process. For example, some kinds of straw with high water content are easy to produce a lot of water vapor during combustion, which affects the combustion effect. If the moisture content of straw is too high and there are too many impurities, it will also affect the effect of briquettes combustion.

2. The briquette machine has poor performance. If the briquette machine has poor performance, such as insufficient pressure and temperature, it will affect the quality and density of briquettes, thus affecting the combustion effect.

3. The storage and transportation of straw after briquetting will also affect the combustion effect. If it is stored for too long or it gets wet during transportation, it will lead to the moisture absorption and softening of straw, thus affecting its combustion effect.

4. The combustion equipment is not suitable. In practical application, straw briquettes usually needs to be burned by combustion equipment, such as boilers and stoves. If the selected combustion equipment is not suitable or operated improperly, it will lead to insufficient combustion of straw briquettes. For example, if the temperature of the equipment is not high enough or the oxygen supply is insufficient, it will lead to insufficient combustion of straw briquettes.

5. Improper operation. If the operation is improper, such as putting too much or too little straw blocks and not cleaning the ash in time, it will also affect the combustion effect.

In view of the above problems, we can take the following measures to solve them:

1. Optimize the quality of straw. Select straw suitable for briquetting, and pay attention to controlling the moisture content of straw and reducing impurities during harvesting, storage and transportation to improve the quality of straw.

2. Optimize the performance of briquette machine. Select a briquette machine with good performance, and adjust the parameters such as pressure and temperature according to the actual situation to obtain better briquetting effect.

3. The storage and transportation of straw briquettes should be done well. Compacts should be stored in a dry place, and long-term storage should be avoided as far as possible, and waterproof and moisture-proof work should be done during transportation.

4. Choose the appropriate combustion equipment. According to the actual situation, the appropriate combustion equipment is selected, and the parameters such as air volume and feed rate are reasonably adjusted to obtain better combustion effect.

5. Pay attention to the operation specifications. In the process of use, pay attention to control the feed rate, clean up the ash and other operations to ensure the combustion effect.

To sum up, the reasons for insufficient combustion of straw briquettes are not single. In order to solve this problem, we need to start from many aspects to achieve complete and efficient straw briquettes combustion.
