In industry contact-surface heat exchangers are used. Deep chilling of burning products is realised in these apparatuses (30–40 oC). At calculation of contact-surface heat exchangers the transfer coefficient of full heat for nozzle chamber s against of determinative factors both for contact part and for irrigated surface heat exchangeris the most important. It may be obtained by several methods. By this there is difficulty at choice of the most effective method, which would provide high accuracy of this value calculation and also would not be too complicated.
