Ⅱ, structural characteristics

YLL/YGL series organic heat carrier furnace is an assembled forced circulation chain grate/fixed furnace boiler. The boiler consists of an upper body and a lower grate/fixed furnace, which is combined on site.
The heating surface of the boiler body is made of close-row circular coil, which is composed of inner and outer two layers of close-row disc tube. The gap between coils is adapted to the fuel, reducing ash accumulation.
Boiler heating surface tube docking to fully automatic gas protection welding process and equipment, can be 100% real-time X-ray online detection. The welding quality is stable and reliable.
The boiler is fully assembled with compact structure, small footprint and short installation period.

Ⅲ, performance advantage

1. High efficiency and energy saving
(1) The boiler adopts the disc tube multi-return heat exchange structure, the heating surface is sufficient, and the output thermal efficiency is high.
(2) The tail is configured with air preheater, steam waste heat boiler and hot water energy-saving device for waste heat recovery according to the use of the user's waste heat, reduce the exhaust temperature, improve the boiler thermal efficiency and reduce fuel consumption.
(3) The grate arch is specially designed, the air chamber independently regulates the air setting, the coal combustion is uniform and sufficient, and the medium adaptability is wide.
(4) The boiler uses high-quality insulation materials and special construction technology, less heat loss, low smoke exhaust temperature, and high thermal efficiency of the boiler.
(5) Combining industrial automation control technology, Internet technology, computer software and artificial intelligence technology to establish an industrial boiler Internet of Things platform, which can realize remote human-computer interaction and data sharing, and realize dynamic control.

2, safe and reliable
(1) The body heating surface adopts close-row coil, and the heating surface is adequately arranged to effectively reduce the heat load on the surface of the pipe, and the use of thermal oil medium is safer.
(2) The medium process is reasonable, the heat transfer oil is from low (import) to high (export), the medium gas generated during operation is difficult to stay in the furnace, and it can be convenient to discharge the system.
(3) Boiler operation adopts remote and near-ground multi-point control, automatic control and monitoring instruments.
(4) The tail convective heat transfer section adopts a special anti-ash structure design and is equipped with a soot blowing device, which has no ash accumulation and high heat transfer efficiency.

3, Environmental protection according to the local plutonium protection requirements to configure appropriate flue gas treatment equipment, flue gas emissions to meet the environmental requirements.
