Why does biomass heat up? Danger of spontaneous combustion accompanying biomass storage

Self-heating of biomass is due to the amount of oxygen, biodegradation and moisture in the pile. Microorganisms decompose organic matter, generating heat, and this process is most intense in the presence of oxygen and adequate humidity. The greatest temperature changes occur in the center of the pile, where these conditions are most favorable and heat accumulates to the greatest extent. As a result, thermal imaging cameras can have difficulty detecting temperature changes over time.

Complete compost temperature monitoring system - wireless temperature sensors and cloud software

Did you know that biomass fires can be effectively predicted and prevented long before they break out? We have a way to do it! Our innovative wireless temperature sensors precisely monitor what is happening at the heart of the biomass pile, where the greatest temperature changes occur. With this early detection system for stack heating, operators get a warning of potential danger long before a fire breaks out. They can then act quickly by rotating the piles using a wheel loader, reducing the temperature and the risk of spontaneous combustion.

Our wireless temperature sensors come in standard lengths (2.5m, 3m, 3.5m, 4m), but also in customized versions on request. With our modular system, you can adjust the length of the smooth or screw-in lance to suit the height of your stacks. These measuring devices are made of stainless steel, which guarantees resistance to cellulose acids and high temperatures. And what about the batteries? With improved battery life, which depends on temperature and transmission intervals (2 s, 15 s, 30 s, 90 s), you can accurately schedule monitoring and maintenance.

Forget about complicated wiring! Our JUMO Wtrans wireless systems operate on radio frequency (868.4 MHz) with an impressive range of up to 2 km. We can handle up to 16 sensors (wTRANS T01 receiver) or up to 32 sensors (JUMO variTRON 300 controller as receiver), providing clear indications and low battery alarms.

Remote access to biomass temperature monitoring data from anywhere - cloud software

Looking for a solution that will work right out of the box, without complicated programming? Our integrated plug and play solutions are tailored to each customer's specific needs. Need support in PLC programming or integration of measurement points with the JUMO Cloud? We are here to help you. With JUMO Cloud's advanced cloud software, you can access real-time data from anywhere, further increasing operational efficiency.

Where is a temperature measurement system used to reduce the risk of biomass spontaneous combustion?

Our measurement systems minimize the risk of biomass spontaneous combustion, which is of great importance to emergency services, power and heating utilities and industrial plant owners. By improving biomass management, we not only reduce the risk of fires, but also reduce their negative impact on the environment by lowering emissions.

We offer proven fire protection concepts for a variety of environments and materials, including:

• Biofuel storage: wood chips, clippings, bark, pellets, sawdust or wood waste.
• Agriculture and farming: straw, hay, peat, grain or compostable materials.
• Industrial waste depots: Garbage centers and warehouses with other waste materials.

Fire protection solutions are crucial wherever large quantities of biomass are stored and the risk of spontaneous combustion is high.

Case study - how did a district heating plant in Sweden benefit from our biomass stack temperature monitoring system?

A district heating plant in southern Sweden provides an excellent example of the effectiveness of JUMO's temperature control system. The district heating plant, faced with the problem of spontaneous combustion of wood chip piles, decided to implement JUMO temperature sensors in combination with plastic sheets on the chip piles. This significantly reduced the moisture content of the fuel and reduced the risk of self-ignition of the biomass dump.

Statement from the Construction Manager: “Previous fires have taught us the importance of being prepared. JUMO temperature sensors give us a very clear indication of the parameters of the biomass piles. We observe that the temperature can change rapidly under certain conditions. When we receive an alert through our SCADA Cloud surveillance system, I can take action quickly.”

By using JUMO's technology, the district heating plant has not only increased its safety, but also set a new standard in the industry, demonstrating how innovative solutions can lead to a solution to the biomass spontaneous combustion problem.
