Abstract

Изобретение относитс к теплоэнергетике , может быть использовано дл получени гор чей воды и пара в нефтеперерабытвающей, химической и других отрасл х промышленности и позвол ет повысить эффективность путем более полной утилизации низкопотенциального тепла . К барабану 1 подключены основной 2 и дополнительный 3 циркул ционные контуры , первый из которых снабжен последовательно по ходу воды установленными насосом 4, выполненным в виде эжектора, и испарителем 5, а второй - подогревателем 7 химочищенной воды, низкотемпературной ступенью 10 потребител 6 тепла, нагревателем 8, высокотемпературной ступенью 11 и подключен обратным трубопроводом 9 к рабочему соплу 12 эжектора 4. Дополнительный циркул ционный контур 3 снабжен также байпасным трубопроводом 13 с клапаном 14, подключенным до низкотемпературной 10 и после высокотемпературной 11 ступеней потребител 6 тепла. Разделение ступеней 10, 11 потребител 6 тепла и применение эжектора 4 позвол ет глубже охладить дымовые газы и нагреть среду в потребителе 6 выше температуры насыщени в барабане 1. 1 з. п. ф-лы, 2 ил. (Л СThe invention relates to a power system, can be used to produce hot water and steam in the refining, chemical and other sectors of the industry and improves efficiency by more fully utilizing low-grade heat. The main 2 and additional 3 circulation circuits are connected to the drum 1, the first of which is equipped with a series of water installed by a pump 4, made in the form of an ejector, and an evaporator 5, and the second by a heater 7 of chemically treated water, a low-temperature heat consumer 10, a heater 8, a high-temperature stage 11 and connected by a return pipe 9 to the working nozzle 12 of the ejector 4. The additional circulation loop 3 is also equipped with a bypass pipe 13 with a valve 14 connected to low temperature urn 10 and after the high-temperature 11 steps of the consumer 6 heat. Separation of the steps 10, 11 of the heat consumer 6 and the use of the ejector 4 allows the flue gases to cool down more deeply and heat the medium in the consumer 6 above the saturation temperature in the drum 1. 1. item f-ly, 2 ill.
