I. Introduction to Air Heating Units

*This equipment is an advanced heating and ventilation device specifically developed by Shandong Shiguang Industrial Equipment Manufacturing Co., Ltd. for industrial and mining enterprises. It features stable performance, long service life, high efficiency and energy savings, diversified control, and a high degree of automation, making it a high-tech product in the ventilation and heating industry.

*The product is divided into two types: steam type and hot water type. The steam type uses steam as the heat source; the hot water type uses hot water as the heat source, with a water temperature not lower than 110°C.

*The product is equipped with an advanced intelligent control system developed by Shandong Shiguang Industrial Equipment Manufacturing Co., Ltd. It can automatically adjust the outlet air temperature and air volume based on changes in environmental temperature, ensuring the comfort and safety of the production environment while saving significant energy consumption. The core heating components of the equipment can be made of various materials such as carbon steel, stainless steel, and copper tubes for users to choose from.

II. Technical Features

1. Stable Performance and Safe Operation

*As this technology uses a highly automated integrated air heater as the core equipment, the outlet air temperature remains constant, and the hot air volume is strictly automatically adjusted according to national safety standards, ensuring that the ventilation temperature of the facility always operates within safe working conditions. This avoids the issue of ventilation temperature at the wellhead failing to meet standards due to unstable heat medium or performance degradation of heat transfer components in conventional air heater designs.

2. Automatic Operation for Unattended Use

*The air heating unit is equipped with an intelligent electric temperature control valve, which strictly controls the outlet air temperature by automatically adjusting the steam flow. The computer control cabinet includes a fan frequency conversion adjustment device that automatically regulates the outlet air volume based on signals from mixed temperature sensors, ensuring the wellhead ventilation temperature always operates within the specified range.

3. Long Service Life with No Overall Performance Degradation

*Conventional air heaters often experience performance degradation after several years of use due to oxidation or other issues with heat transfer components, leading to operational failures. Hot air furnaces also suffer from performance degradation and shorter lifespans over time due to oxidation and corrosion during idle periods. While heat exchange components in air heating units may also experience performance degradation under working conditions, this can be compensated for by the automatic control system adjusting the ventilation air volume, ensuring long-term safety of the ventilation facilities. Additionally, air heating units are not subject to sulfur dioxide corrosion, resulting in a longer service life. Due to the use of highly stable components, the service life of air heating units can exceed 10 years.

4. Outstanding Energy-Saving Effects

*Thanks to automatic intelligent control, energy consumption is strictly regulated according to wellhead ventilation requirements, resulting in steam consumption being only half that of conventional air heaters.

*In traditional air heater hot air systems, manual control often leads operators to set the wellhead operating temperature at 5°C or higher to prevent risks from low temperatures, resulting in energy consumption 2-3 times higher than the operational requirement (2-2.5°C).

*With air heating unit technology, the energy savings from ventilation facilities in the first year can more than cover the entire equipment investment. Additionally, frequency conversion technology can save over 30% of fan power consumption.

5. Highly Integrated Electromechanical Structure for Easy Installation, Maintenance, and Management

*The air heating unit integrates high-performance heat transfer components, fans, and an automated control system into a cohesive unit, simplifying installation, operation, and maintenance.

*Inlet air temperature, outlet air temperature, wellhead temperature, and heat medium temperature are all displayed on the control cabinet’s LCD panel, making all parameters clear at a glance. Information can be remotely transmitted via an R485 interface, enabling computer-based remote monitoring and greatly facilitating management.

*Multiple units at each wellhead share a single computer control cabinet, automatically starting, shutting down, and alternating operation based on actual needs.

*This technology leverages science and technology to enhance safety, energy efficiency, and production efficiency.

6. Clear Advantages Compared to Hot Air Furnaces

*Overall Investment—Both equipment and construction costs are lower than those of hot air furnaces.

*Management and Maintenance—Much simpler than hot air furnaces, with no need for manual supervision.

*Fuel Adjustment—Hot air furnaces typically use either coal or gas. If coal is used, operating costs are high, and瓦斯 gas cannot be utilized. If gas is used, the瓦斯 gas emission concentration during initial production or before batch production may not meet requirements, making gas hot air furnaces potentially unusable. In contrast, air heating units can freely switch between coal or gas boilers in the boiler room based on actual conditions.
