Why should straw be burned into pellet fuel?

The current straw pellet fuel is to use straw fuel pellet machine equipment to process biomass into straw pellets or rods and blocks that are easy to store, transport and use. Prosperous, the black smoke and dust emissions during the combustion process are very small, the SO2 emissions are extremely low, the environmental pollution is small, and it is a renewable energy that is convenient for commercial production and sales.

Straw fuel is generally processed into pellets or blocks, and then burned, so why can’t it be burned directly, and what are the pros and cons? In order to solve everyone’s mysteries, let’s analyze the difference between straw pellet fuel and direct combustion of straw raw materials.

Disadvantages of direct combustion of straw raw materials:

We all know that the shape of straw raw materials before being processed into straw pellet fuel is mostly loose, especially when using agricultural straw. Between 65% and 85%, the volatile matter begins to separate out at about 180 °C. If the amount of combustion accelerant (oxygen in the air) provided at this time is insufficient, the unburned volatile matter will be carried out by the airflow, forming a large amount of black. Smoke has an adverse impact on the environment. Secondly, the carbon content of the straw raw material is small, and the duration of the fuel process is relatively short, and it is not resistant to burning.
After volatilization and analysis, the crop straws form looser charcoal ash, and a large amount of charcoal ash can be formed by very weak airflow. Another reason is that the bulk density of straw raw materials is very small before processing, which is inconvenient for the collection and storage of raw materials, and it is extremely difficult to form commercialization and sales management, and it is not easy to transport long-distance;

Therefore, straw pellet fuel is generally processed into pellets or blocks by straw fuel pellet machine equipment and then burned. Compared with unprocessed straw raw materials, it has better utilization value and environmental protection advantages.
