The lance desuperheaters are most frequently equipped with one injection nozzle and are recommended for the pipelines up to DN100. cooling water injection Steam pipeline Fig. 5 Lance desuperheater 3. Injection valves. The role of injection valves is usually played by the control valves of the Z1A type. Due to the parameters of the cooling water, in many cases it is necessary that the valve be anti-cavitational. Fig. 6. Valve of the Z1A type, with a multi-stage valve head and a choking cage. 128 Revision: SRS/07/2014 Valid till next revision.
