2results about How to "Solve spontaneous combustion" patented technology

The application discloses a biomass powder hot air feeding and blending combustion system, which comprises a stock bin, a belt conveyor, a dryer, a boiler, a burner, an air preheater and a dust collector. The air outlet end of the boiler is connected with the air preheater, and the flue gas outlet end of the air preheater is connected with the dust collector. The dust collector is connected with a flue gas discharge pipeline structure. The air preheater is assembled with a secondary air pipeline structure. The air inlet end of the dryer is assembled with an induced draft fan. The flue gas discharge pipeline structure and the secondary air pipeline structure controlled by a valve are connected with the air inlet end of the induced draft fan. The induced draft fan pumps the feeding hot air formed by the secondary air and the dust-collected flue gas into the dryer to dry the material. The application also discloses a blending combustion method based on the blending combustion system, which comprises the conveying of the biomass material and the controlled conveying of the secondary air and the dust-collected flue gas to realize the controlled blending combustion. The blending combustion efficiency of the biomass is greatly improved by the technical scheme.

This application relates to a movable coal-fired spontaneous combustion prevention and monitoring device and method for use in silos. The device's power supply module moves periodically along a preset path laid out on the inner wall of the silo, and is connected to a control module to supply power to the control module. The control module is mounted on the power supply module and connected to a temperature monitoring module. The temperature monitoring module includes a telescopic temperature sensor and a temperature sensing element mounted on the telescopic temperature sensor. Under the action of the control module, the telescopic temperature sensor extends relative to the control module to insert into the coal inside the silo and measures the temperature through the temperature sensing element. It also retracts relative to the control module to detach from the coal. This method enables automatic monitoring of coal pile temperature changes periodically, saving manpower. The telescopic temperature sensor, when extended and inserted into the coal, monitors a wide range of temperature changes within the coal pile, facilitating early warning and timely detection of early spontaneous combustion hazards.
