Common methods for cleaning of heat conduction oil boiler
Heat conduction oil boiler is a common organic heat conductor boiler in our daily life, but in the process of use, because of the special medium of heat conduction oil boiler, it is unavoidable to accumulate carbon, precipitation, and coking in the boiler after a period of time. Therefore, the daily maintenance and cleaning of the heat transfer oil boiler are mainly aimed at clearing the dirt such as coking and carbon deposition. Below, Qingdao Shengli boiler tells us about the cleaning method of the heat conducting oil boiler.
First, defocus cleaning
Coking is the most common phenomenon in heat conducting oil boiler, so it is also the most important to remove coking. First of all, the special cleaning agent should be blended and diluted. The dilution principle is calculated according to the thickness composition of the coke and the type of heat conducting oil. When the water level is half filled to the upper trough, the temperature should be maintained between 90 and 95. Soak for one day (the specific time can also be determined according to the situation of coking).
Two. Rinse and rinse
After the first stage of coking and cleaning, there will be residual liquid and dirt in the flue gas system. Therefore, carbon removal cleaning agent should be added to carry out cleaning, and washed with clean water until the coke removal cleaning agent has no foam, water is clear. The water temperature should be kept between 85 - 95 degrees Celsius during cleaning, and the time should be 6 hours. The boiler size and operation are different, and the time can be adjusted by itself.
Three. Blowing steps
After the heat conduction oil boiler is cleaned in detail, a part of the water stain will be left at the pressure gauge or other connections, which will affect the normal use of the boiler. Therefore, the air compressor should be added to these connections, and the pressure is raised to between 0.3 and 0.4MPa, at the low point, and the operation is repeated until the water is blown dry.
