5 results about "Biomass briquettes" patented technology

Biomass briquettes are a biofuel substitute to coal and charcoal. Briquettes are mostly used in the developing world, where cooking fuels are not as easily available. There has been a move to the use of briquettes in the developed world, where they are used to heat industrial boilers in order to produce electricity from steam. The briquettes are cofired with coal in order to create the heat supplied to the boiler.

Coal briquette manufacturing device and manufacturing method thereof

PendingCN122165688AWaste based fuelShaping pressCoal briquetteResidual biomass
This invention discloses a briquette manufacturing device and its manufacturing method, relating to the field of biomass coal production technology. The briquette manufacturing device employs a double-acting structure with reciprocating pressure in its pressurizing mechanism, abandoning the traditional unidirectional, single-stage forming mode. Two briquette formations can be completed in a single reciprocating motion, doubling the number of briquettes formed per unit time and significantly improving biomass briquette production efficiency, making it suitable for large-scale continuous production. The shaping mechanism adopts a split-type dual-station structure, with the upper and lower shaping components simultaneously and independently completing feeding, forming, and discharging without interference. Combined with two separate conveyor belts, it achieves nearly double the production capacity within a single unit's volume. The pressurizing component integrates an upper cleaning scraper, a lower cleaning scraper, and a lifting column linkage structure, automatically scraping away residual biomass raw materials from the inner wall of the mold during pressurization and resetting, preventing raw materials from sticking to or clogging the mold, ensuring a smooth briquette surface, stable forming accuracy, and reducing the defect rate.

A biomass cascade gasification gas making device

This application discloses a biomass cascade gasification gasification device, relating to the field of biomass gasification. The primary gasification system uses superheated steam and oxygen as gasifying agents, offering strong raw material adaptability; it can use biomass briquettes or regular bulk biomass, resulting in low raw material pretreatment costs. A fluidization device ensures a uniform temperature field in the primary gasifier, reducing the likelihood of coking. A return feeder returns semi-coke particles separated by a cyclone separator to the primary gasifier, allowing them to participate in the gasification reaction again, improving biomass raw material utilization and reducing semi-coke ash emissions. Based on this, the primary gasification system can reduce raw material pretreatment costs and semi-coke ash emissions. The secondary gasification system introduces pure oxygen and uses non-catalytic oxidation technology to remove impurities carried in the crude syngas through high-temperature cracking. A quench device cools the high-temperature crude syngas, reducing dust and ash accumulation and facilitating subsequent waste heat recovery. Based on this, the secondary gasification system can reduce the impurity content in the crude syngas and lower the crude syngas purification cost.
