2.Product advantages
The trolley-type energy-saving gas-fired roasting furnace breaks away from its reliance on heat storage media and instead employs a synergistic approach combining precise combustion, efficient heat retention, and intelligent control. On the heat generation side, its proportionally modulated burner monitors furnace temperature in real time and dynamically adjusts gas and air flow rates via a PLC system. When the furnace temperature falls below the set point, the burner automatically increases gas supply (with an accuracy of ±0.5% flow rate) and simultaneously adjusts the air damper to an optimal air-fuel ratio of 9.5:1, ensuring sufficient combustion (with a thermal efficiency exceeding 85%). On the heat retention side, the furnace body utilizes a composite insulation structure comprised of ceramic fiber modules and lightweight refractory bricks. The ceramic fiber modules have a room-temperature thermal conductivity of only 0.03W/(m·K). Combined with the labyrinth seal on the furnace door and the sand seal on the trolley, the furnace surface temperature (at an ambient temperature of 25°C) can be controlled below 60°C, reducing heat loss by 60% compared to traditional furnaces. More crucial is its "continuous temperature control without reversing" design: 8-12 K-type thermocouples are distributed throughout the furnace, collecting real-time temperature data from each zone. A PID temperature control algorithm fine-tunes the burner output in each zone based on these data differences (for example, when the furnace ends have low temperatures, the sidewall burner power is automatically increased), maintaining a stable temperature deviation within ±3°C. This entire process eliminates the need for regenerative elements, avoiding reversing losses and aging issues. Heat utilization efficiency is increased from 50%-60% in traditional equipment to over 80%.
