Self Cleaning Heat Exchanger

[User2000]

Hello

Does anybody know where I can find some technical papers, or manufactures, about "self cleaning" heat exchangers?
I have special interested on vertical reboilers with process inside tubes because it has around 10% to 40% of a mixture of organic and inorganic solids dispersed in water.

Best regards

The spiral plate heat exchanger is normally referred to as self cleaning. From memory they were first produced by Rosenblad who were purchased by Alfa Laval. The plates are coiled up like a scroll of two papers. They work well and are expensive. Improvements in ordinary plate exchanger self cleaning ability have greatly reduced their demand.

Try googling spiral heat exchanger and see what you get.

You may be better looking at lanced tube type systems. These are not self cleaning but use pressure jets on moveable lances, a bit of a cross between a water blaster and a soot blower.
