Biomass Power Plant Combustible Material Stack Temperature Monitoring and Early Warning System

Bio-power plant combustible material stack temperature monitoring and early warning system, haystack and straw stack anti-spontaneous combustion temperature measurement system. Flammable stack temperature monitoring anti-spontaneous combustion alarm system. Biomass power plant fuel anti-spontaneous combustion wireless temperature measurement system, bio-power plant anti-spontaneous combustion, fuel stack temperature measurement system. The acquisition process of power plant fuel is more complex compared to the recycling of other materials, including multiple steps such as collection, crushing, packaging, and transportation. If the fuel's moisture content increases during the above acquisition process, it poses a potential risk for spontaneous combustion.

When the moisture content of biomass power plant fuel increases, its temperature rises continuously due to microbial activity. When the temperature reaches a certain level and comes into contact with air, further oxidation occurs, which can immediately lead to spontaneous combustion. Different types of biomass power plant fuels have varying densities and ignition points, making spontaneous combustion likely when they are mixed and stored together.

Biomass power plant fuel, due to its low density and low ignition point, carries a high fire risk. Considering the characteristics of biomass fuel, the main causes of spontaneous combustion are excessive moisture, mixed storage, and improper stacking. Corresponding preventive measures are proposed. Biomass fuel stack anti-spontaneous combustion_Wireless temperature measurement system. At the same time, to effectively reduce fire risks and control fuel fire incidents, it is necessary to consider both the inherent properties of waste fuel and the fire prevention design practices of biomass power plants to ensure the safety of biomass power plants.

In actual production, the use of various solid fuels is increasing, making biomass fuel temperature measurement and fuel management increasingly complex and challenging. Among these challenges, the heating and spontaneous combustion of flammable solid stacks are becoming more severe. Traditional manual temperature inspections and the "burn old, store new" system are increasingly inadequate to meet current production needs and cannot effectively curb the heating and spontaneous combustion of solid flammable stacks.

The acquisition process of power plant fuel is more complex compared to the recycling of other materials, including multiple steps such as collection, crushing, packaging, and transportation. If the fuel's moisture content increases during the above acquisition process, it poses a potential risk for spontaneous combustion. The biomass power plant fuel anti-spontaneous combustion/wireless temperature measurement system addresses several scenarios: first, inadequate drainage facilities in the storage yard, where rainwater cannot be discharged in time, leading to fuel immersion; second, insufficient covering measures for the top of the fuel; third, low stack foundations, causing rainwater to flow back to the bottom of the stack.

Considering that many stacks have raw materials from different sources with varying characteristics, a strategy of inserting multiple temperature measurement cables for each batch can be adopted. This approach allows the measurement points to better reflect the heating and spontaneous combustion conditions of that batch. Through joint research with a university, our company conducted continuous long-term monitoring of ground stack spontaneous combustion ignition temperatures. We collected nearly 100,000 temperature data points, including temperature changes at different stack depths and states before spontaneous combustion (such as steam emission, smoke, and dense smoke). By studying and analyzing the collected data, we discovered certain patterns in the relationship between stack depth and temperature that can serve as a reference. When the temperature at a measurement point reaches the warning level (which can be set), the software will issue an alarm. On-site personnel must take timely action, locate the spontaneous combustion point near the measurement point based on its description, promptly open the stack, cool it, re-compact it, reinsert the temperature measurement cable, and continue monitoring the stack.

Inner Mongolia Deming Electronic Technology Co., Ltd. is a company integrating research and development, production, sales, and after-sales service. Relying on strong technological advantages and intelligent control as its core, the company continuously expands its application fields. Its industries cover wireless LORA sensors, NB-IOT temperature and humidity.

If not handled in time, once the stack temperature exceeds a certain level and enters the rapid oxidation phase, it will quickly heat up and spontaneously combust, potentially spreading to larger areas of the stack and causing losses. If the affected area is too large, it may become unmanageable. The system features layered, automatic, and timed data collection, wireless transmission, and integrated modeling with graphical curves and lists. It offers comprehensive functions, stable performance, explosion-proof design, reasonable cost-effectiveness, convenient and flexible use, no environmental restrictions, long transmission distance, and data recording for up to 2-5 years. Stack fires are among the more serious fire incidents in biomass power plants, primarily caused by heat accumulation within the stack. Combined with large fuel reserves, if high-density hard materials such as leaves and bark are present, spontaneous combustion is highly likely. If strong winds occur during spontaneous combustion, the fire's scope and severity can worsen, leading to unpredictable adverse consequences.
