Although incineration of farmland residues is a traditional treatment method, it is necessary to pay attention to its potential impact on the environment, health and safety. The following technical recommendations for accelerated combustion are provided, but it is more recommended to give priority to sustainable alternatives.**： --- ###️️ Important prerequisites 1. **Confirmation of legality**: Many regions have legislated to prohibit open-air incineration (such as China's "Air Pollution Prevention and Control Law"). Be sure to verify local policies before incineration. 2. **Safety assessment**: Avoid operating in dry and windy weather, stay away from flammable substances, and prepare fire extinguishing tools (water, sand, etc.). 3. **Health protection**: The smoke contains PM2.5 and harmful gases. The operator needs to wear a mask and notify the surrounding residents to close the doors and windows. --- ###技术Technical methods for accelerating combustion 1. **Physical processing** -**Crushing residues**: Use machinery to chop the straw below 10cm to increase the contact area with oxygen. -**Stacking structure**: The shape of a “well” or hollow stacking is used to promote air circulation (to avoid tight compaction). 2. **Control humidity** -Choose continuous sunny incineration, with the highest combustion efficiency when the moisture content of the residue is less than 15% (can be tested by hand kneading: it is advisable to be fragile and no moisture exudates). 3. **Use of combustion aid** -**Bio-based combustion aids**: Such as special microbial decomposers for straw (safer than diesel/gasoline, but need to be sprayed 3-5 days in advance). -**Ignition belt design**: Use dry flammable materials (such as withered grass) to lay the ignition line at the upper entrance to form a continuous ignition line. --- ###的 More recommended environmentally friendly alternative | Method | Operation method | Long-term benefits | |---------------|-----------------------------------|--------------------------------------| | * * Straw is returned to the field ** | Plowed into the soil after crushing (depth 20-30cm) / Improve soil organic matter and reduce fertilizer use | /**Biomass power generation**/Cooperate with recycling companies to centrally process|generate clean energy, and government subsidies are available in some areas| | ** Compost fermentation * * / Mixed livestock and poultry manure, covered with fermentation membrane | converted into organic fertilizer in 3-6 months to reduce planting costs | --- ### 📌 Key recommendations -**Consult the local agricultural department**: Find out if there is a subsidy policy for straw treatment (such as preferential leasing of returning machinery to the field). -**Pilot small plots of farmland**: If you insist on burning, you can first try to burn an area of less than 1 acre to observe the spread of fire and smoke. **In the long run, adopting a sustainable approach can not only avoid legal risks, but also improve soil health and reduce production costs. ** If you have specific needs (such as soil improvement methods), you can further communicate and refine the plan.
