We have low thermal efficiency for coal-fired furnaces, and the furnace life cycle is short. Especially when the furnace is in the late stage of use or encounters poor coal quality, it is difficult to produce, and the annual kiln maintenance cost is very large. The quality of the material meets the requirements of the technical requirements, and the unqualified materials are resolutely prevented from being used in the furnace. In addition, the furnace and kiln engineering technicians continue to sum up experience on the existing basis to absorb advanced technology and continue to innovate. The No. 1 furnace was piloted and reformed, and a bold attempt was made on the straight part of the firing chamber of the kiln. The original single-sided cooling was changed to double-sided heat dissipation. A grid brick was built in the inner section of the fire tunnel, and the gap was used for heat dissipation. Heat is returned to the firing chamber through the gap, which greatly increases the thermal efficiency. In addition, the roof cover is also modified. In the past, 12 pieces of large material height were used. Each time, eight pieces of each unit were used to make a single firing chamber. The upper top cover part was lightened to reduce the weight of the lattice brick due to the top of the furnace. The pressure has prolonged the use time of the kiln. From the transformation to the replacement of the arc-striped bricks inside and outside the kiln, the straight plaque bricks have been used for 18 months, and the kiln temperature after the transformation Pick up fast. Practice has proved that the transformation of this furnace has achieved good practical value and economic benefits. The mechanical pressing material of the forging mechanical mechanical shearing machine The function of the new material shearing device is to press the sheet tightly on the workbench before cutting, and then release the sheet after cutting, otherwise the sheet will A displacement is generated to increase the dimensional deviation.
Thermal Oil Boiler is a new type of special boiler with low pressure and high temperature working characteristics. Thermal oil boiler uses hot oil as heat transfer medium, hot oil circulation pump to make the medium has a forced circulation, then deliver the heat to heating need equipment and then go back to the heating furnace. It adopts horizontal chamber-fired three-coil pipe structure, the boiler body is composed of an outer coil pipe, a middle coil pipe and an inner coil pipe. Thermal oil boiler can be used for heating in various production process where the heating temperature is between 150℃ and 350℃.
