Assessment of the possibility of using heat-insulating and energy-saving equipment

Abstract

The article deals with the problem of energy saving in the context of comparing contact heat exchangers. The advantages and disadvantages of various schemes are analyzed. It is proposed to use economizers of contact heat exchangers with active packing (HEAP) in boiler units of boiler houses. An analysis of the operation of one of the types of HEAP is given. The advantages of using HEAP with a two-circuit apparatus with a nozzle are considered. The main utilization plants and their parameters are described. Examples of the creation of designs for double-shell contact heat exchangers for the utilization of low-potential internal (side) energy resources (IER) are given. For branches of the chemical industry, a scheme of a scrubber-salt system using an intermediate heat carrier is proposed. The effective use of these devices for heating and humidifying air in ventilation and air conditioning systems is noted. The pros and cons of contact heat exchangers are considered in the framework of increasing the efficiency and environmental friendliness of the schemes. The ways of further increasing the efficiency of HEAP are consid
