Operation of Ru-Therm heating system is based on heat transfer process from the profile heat tracer to the product to be heated through the walls of the pipeline, tank or a technological unit. Development of mathematical model based on thermophysical calculation makes it possible to achieve product uniform heating in all heated areas. By using a specially developed thermal paste and enlarged contact spot of the heat tracer, it is possible to achieve maximum heat transfer efficiency.
When developing a mathematical model, we take into account the type of the medium to be heated, flow rates, heating features, pipeline materials, ambient temperature, thermal insulation, etc.
Various liquid media can be used as a heat carrier: glycol solutions, steam, heating water, etc.
To warm up the heat carrier, the excess heat from technological units can be used, which makes it possible to increase the energy efficiency and environmental friendliness of the enterprise.
Development of the Ru-Therm heating system is carried out in several stages:
It is possible to supply the entire system on a turnkey basis, as well as to supply its individual elements to the Customer to build the system independently. Usually this option is applicable if the temperature regime for the pumped product is not critical and a thermophysical calculation with subsequent mathematical modeling is not required.
Math modeling makes it possible to predict the heat flux vectors and temperature fields distribution, as well as the heat losses dynamics, and to select the heating power and thermal insulation needed.
Ru-Therm heating system consists of the elements as follows:
The heat tracer is a profiled steel pipe plugged from both ends, to be laid along the process pipeline or technological equipment, through which the heat carrier is pumped. The largest side of the rectangular pipe is made concave with a radius equal to the radius of the outer surface of the object to be heated. Heat tracers are delivered to the assembly site in the form of finished products.
The assortment and geometry of heat tracers is designed in such a way as to provide maximum coverage of surfaces to be heated in order to maintain a temperature regime set throughout their entire length. The choice of the heat tracer geometry is determined by mathematical modeling, which allows predicting the process equipment wall temperatures and the working medium, taking into account the flow rate, thermal conductivity, wall thickness, manufacturing material, the number of elements of the process equipment, as well as the influence of environmental factors.
