The production of steam using solar energy concentrator for different climate zones is investigated. The method for calculating the capacity of the solar concentrator located at an arbitrary angle to the horizon is given. The characteristics of the cylindrical- parabolic concentrator according to the magnitude of the incoming solar radiation are calculated. The steam generation by solar concentrator at different values of solar radiation are determined. The daily generation of steam in July, for the conditions of Russia (Ekaterinburg), Tajikistan and Egypt is calculated. The experimental tests for conditions of Russia for the purpose of verification methods for determining the performance of the concentrator, the results of which coincided with the calculated values are conducted. The average daily value of the specific consumption of steam generated by the concentrator will be 137 g/(m 2-h) for Russia, 190 g/(m 2-h) for Tajikistan, and 214 g/(m 2-h) for Egypt. Perhaps the widespread use of solar concentrator to produce steam for technological and domestic needs in countries wealthy by solar radiation.
