After the installation of the hot oil boiler, a medium is needed to operate the whole boiler system, that is, the hot oil of the boiler. People usually compare the heat-transfer oil to the blood of the heat-transfer oil boiler. What should we pay attention to when the heat-transfer oil is put into use?
The boiler manufacturer promises to use hot oil boiler to stop cleaning the furnace and pipes, remove the rust and water vapor of impurities in the furnace, and ensure the use of equipment is clean; when cold oil is injected into the high-level tank of the hot oil boiler, the temperature shall be below 80 ℃ to participate in the hot oil, so as to prevent the boiling of hot oil; when the hot oil boiler starts to operate, start the circulating oil pump, operate in the cold state for 1-2 hours, and then ignite for heating.
使用导热油锅炉导热油次慢慢加热,温度10℃左右,每小时加热到80 ~ 120℃时应缓慢升温,脱水阶段的时期,这个时候热油泵压力计,压力表等震动,应暂停,恒压火一段时间,待蒸汽排放后继续加热,控制升温速率约20℃/小时。
Use the heat transfer oil boiler to heat the heat transfer oil slowly for the first time at a temperature of about 10 ℃. When it is heated to 80 ~ 120 ℃ every hour, the temperature shall be raised slowly. During the dehydration stage, when the pressure gauge and pressure gauge of the heat pump vibrate, the temperature shall be suspended and the fire with constant pressure shall be kept for a period of time, and the heating shall be continued after the steam is discharged, and the heating rate shall be controlled at about 20 ℃ / hour.
When the heat transfer oil of the boiler is heated to 180 ~ 220 ℃, this section is the weight reduction section. At this time, it is necessary to control the constant temperature for a period of time, and then raise it to the working temperature for normal use. Before the hot oil of the circulation system enters the hot oil boiler body, a 30-40 mesh stainless steel wire filter shall be installed to filter the welding slag, impurities and carbon residue that may be generated.
