What are the characteristics of a double pipe heat exchanger?
A double pipe heat exchanger is a type of heat exchanger that works by using two pipes to carry out its work. This unit is commonly used for transporting air and heat. The goal of a heat exchanger is to allow two separate flows to interact at a conductive barrier, which can allow thermal energy transfer.
What is the result of the heat treatment of calcium carbonate caco3?
Calcium carbonate decomposes on heating to form calcium oxide and carbon dioxide.
How do you remove calcium from a heat exchanger?
To remove limescale from heat exchangers, condensers and chillers we recommend chemical treatment using Envirofluid's range of Worksafe descalers. The Triple7 range is a formulation of surfactants and other Worksafe chemicals that will not harm equipment or endanger workers.
What is the thermal conductivity of calcium carbonate scale?
The thermal conductivity of calcium carbonate is 2.7 W/(m*K) as compared to less than 0.5 for neat polyolefin resins.
