2. Structure introduction
2.1. The skeleton of the furnace body is welded by various large and medium-sized steel sections on site.
2.2. The furnace lining adopts a full fiber structure, which saves about 65% energy compared with the brick furnace. It uses high-quality long-fiber thorn blankets as raw materials, and uses special equipment to make modules, and a certain amount of compression is reserved during the processing process to ensure that the modules are built in masonry. After completion, each ceramic fiber block expands in different directions, so that the modules are squeezed together into a whole without gaps, so as to achieve a perfect heat storage effect. The fiber blocks are fixed by the ceramic nails. The advantages of the product are low thermal conductivity, low heat capacity, excellent corrosion performance, excellent thermal stability, thermal shock resistance and thermal insulation, and the anchors are arranged on the cold surface of the furnace body, which improves the high temperature resistance of the fiber.
2.3. The frame of the trolley is welded by various large-scale I-beams, channel steels, angle steels and thick steel plates. The trolley transmission adopts the combination of electric motor and worm gear reducer to drive the front-end driving wheel transmission through the chain. The refractory masonry of the trolley adopts a high-alumina shaped brick structure, which has good sealing effect with the furnace body and high compressive strength. The trolley and the furnace body are sealed by soft contact, and a labyrinth sand sealing groove and a sand sealing knife sealing device are arranged at the lower part of the trolley.
2.4. Combustion system: several burners are installed on both sides of the oil furnace, and the heat flow reciprocates in the furnace to ensure the uniformity of furnace temperature.
2.5. Smoke exhaust preheating device: a smoke exhaust preheating device is installed at the upper end of the furnace. When the flue gas in the furnace passes through the preheater, it is sent to the cold air by the fan for preheating, and then sent to the burner by the pipeline for combustion support. , and install a manual butterfly valve at the outlet, which can adjust the pressure in the furnace.
2.6. The control system adopts chain control, the digital display shows the temperature, and the contactor controls.
