Biomass Fired Thermal Oil Boiler

Vertical type coal/biomass fired thermal oil boiler is a high-temperature heat source that operates below 350℃, using coal or biomass as fuel and thermal oil as the heat carrier. It is widely used in industries requiring high-temperature heating or drying. This thermic fluid heater has the advantages of high temperature, low pressure, precise temperature control, and high thermal efficiency.

Structural characteristics

• YLL/YGL series thermal oil boiler(also called thermic fluid heater) is an assembled forced circulation chain grate/fixed grate boiler. The boiler consists of an upper body and a lower movable chain grate/fixed grate, which can be assembled on-site.

• The heating surface of the boiler body adopts a tightly packed circular coil, consisting of inner and outer layers of tightly packed circular coils. The gap between the coils is adapted to the fuel to reduce ash accumulation.

• The boiler heating surface pipes are butt-welded using automatic gas protection welding technology and equipment, with 100% real-time X-ray online detection. The welding quality is stable and reliable.

• The boiler is fully assembled, with a compact structure, small footprint, and short installation cycle.

Advantages

High efficiency and energy-saving:

• The radiant heat transfer surface of the boiler body adopts a tightly packed coil structure, and the convective heat transfer surface of the flue gas adopts an S-shaped multi-return heat transfer structure, with a high heat transfer coefficient and high thermal efficiency.

• The boiler is equipped with a high-efficiency air preheater or economizer at the tail to absorb the waste heat in the flue gas, reduce the exhaust gas temperature, increase the thermal efficiency, and reduce fuel consumption.

• The boiler uses high-quality insulation materials and special construction technology with low heat loss.

• The special design of the grate arch, with independent adjustment of the air volume, ensures uniform and sufficient combustion of coal or biomass fuel, with wide adaptability.

• The forced draft fan and induced draft fan are controlled by frequency conversion.

• The industrial boiler IOT platform is established based on combining industrial automation control technology, Internet technology, computer software, and artificial intelligence technology, which can achieve remote human-machine interaction and data sharing, and realize automatic control.

• The heating surface of the boiler body adopts tightly packed coils, with sufficient layout of the heating surface, effectively reducing the surface thermal load of the tubes, and ensuring the safe use of the thermal oil medium.

• The medium flow is reasonable, with the thermal oil flowing from low (inlet) to high (outlet), making it difficult for the medium gas generated during operation to stay in the furnace, and facilitating the discharge of the system.

• The top of the furnace is equipped with a tightly packed coil top arch design to avoid damage to the furnace top, with a long continuous use cycle.

• The boiler operates using remote and local multi-point automatic control, with complete monitoring instruments.

According to local environmental protection requirements, appropriate flue gas treatment equipment is configured to ensure compliance with environmental protection standards for flue gas emissions.
