Import Biomass Pellet Fired Thermal Oil Heater — Buy in wholesale FOB from Supplier in China

Beijing Bidragon Machinery Co., Ltd. manufactures the YLL Chain Grate Biomass Pellet Fired Thermal Oil Heater in Beijing, China. The system uses waste wood and biomass pellet fuel to heat thermal oil in tube bundles, with the heated oil circulating in a closed loop to transfer energy to downstream equipment. The source highlights a low working pressure design achieving 300 degrees Celsius at atmospheric pressure, though rated thermal capacity in kW or MW is not stated. The chain grate combustion method is specified, a positive feature distinguishing this model from fluidized bed or suspension burner alternatives.

The YLL series employs hot oil as heat carrier rather than steam, enabling precise temperature control for processes with varying heat demand. Cloth pipe protection at the furnace top is included to prevent burnout, and middle ash removal is designed to prevent furnace tube clogging, a common failure mode in biomass combustion. The flow path from low to high elevation aids gas venting, which the source claims improves thermal efficiency. Standard construction materials for such heaters include boiler-grade carbon steel for pressure parts and refractory lining in the combustion chamber, though Bidragon's specific material grades and thicknesses are not provided.

This thermal oil heater suits industries requiring medium-temperature process heat without the regulatory burden of steam boiler codes, such as plywood drying, bitumen heating, edible oil processing, and chemical reactor heating. The closed-loop thermal oil system eliminates condensate handling and water treatment. Buyers should confirm with Beijing Bidragon whether the supply includes thermal oil pump, expansion tank, and deaerator, or if these balance-of-plant items are procured separately. Also clarify fuel feed system type, storage silo requirements, and whether the grate is water-cooled or air-cooled for the intended fuel moisture range.

Beijing Bidragon Machinery Co., Ltd. is located at No.16 South-West Third Ring Road, Beijing, China, with a postal code of 455000 that appears inconsistent with Beijing's standard 100000 series, suggesting a possible data entry issue to verify. The company holds a harbor trust tier with zero response rate and zero average response hours, indicating no active communication is recorded on the platform. No verification documents, trade show attendance, or audit records are visible in the provided facts. The Beijing location places it within China's capital region, with access to engineering talent and supply chain networks, but this geographic advantage does not substitute for supplier due diligence.

The listing contains no information about establishment year, registered capital, factory floor area, number of employees, annual production capacity, or export volume. No named clients, project references, or installed base statistics are provided. The YLL product designation suggests a series code, but no model number breakdown or capacity range is given. Buyers should request company profile, manufacturing license for pressure vessels or boilers if applicable in China, and evidence of quality management system certification. Direct factory visit or third-party factory audit is recommended given the limited verification signals available.
