SJT Steam Jet Thermocompressor
Description In this environmentally conscious world, companies within the Process Industries Sector are becoming more aware of the additional cost savings that can be made at the same time as committing to a friendly environment. One such common area is the steam raising plant and the proportion of waste product that is put to atmosphere. If the amount of waste can be reduced and thereby have an effect on the amount that is being generated in the first place, then the environment will be improved and the running costs reduced. It is in this area of operation that the application of an SJT Steam Jet Thermocompressor can be advantageous. Spirax Sarco has been designing innovative solutions for steam plant engineering and cost effective manufacturing for over 25 years. The Steam Jet Thermocompressor is a prime example of this commitment; the SJT is an energy saving device that compresses low pressure steam, often waste steam, to a higher useable pressure. All of Spirax Sarco's SJT Steam Jet Thermocompressors are designed and built to the customers specific criteria, for their intended application, to provide optimum performance and return on investment. An SJT Steam Jet Thermocompressor can be described as a type of Ejector. It uses a jet of high pressure steam (called the Motive pressure) to entrain low pressure water vapour (called the Suction pressure). The two medium's are intimately mixed and subsequently discharged at a pressure that lies somewhere between the motive and suction pressures. Advantages over electromechanical alternatives : - Simple construction; SJT Steam Jet Thermocompressors can be made from any machineable materials for increased abrasion resistance. - Compact design and comparatively lightweight which enables overhead installations. - Low capital cost and operating costs. - No moving or rotating parts with minimal maintenance and therefore the units can be installed in remote or inaccessible locations. - No specialist maintenance experience required. - Discharge steam is oil free, no lubrication contamination.
