Condensate must be drained manually to prevent steam hammering. Steam Blowing; Purpose of steam blowing Cleaning by steam blowing is carried out essentially for steam circuits i. Blowing of the piping system will be considered completed and cleaned upon two consecutive targets after blowing, resulting in less than two pits per square cm with a maximum diameter of 0.
The steam headers should be slowly warmed up, one header at a time, while expansion of the line is observed. On older units the need for steam line blowing should be considered following major pressure parts repairs, where the possibility of introduction of foreign material into the system exists.
Since prevention of damage to the plant steam system is the prime concern, the responsibility for determining the effectiveness of the steam line blowing operation Boiler research paper with the plant operator. Condensate lines may be cleaned in the same manner as steam lines.
Each drain valve lateral to header, exchangers, or service lines should be blown in the same manner, usually not more than one at a time. The headers should now be blown using a low pressure, high-velocity sweep as explained hereafter. The purpose of blowing or cleaning the steam lines prior to starting up a new unit is to remove any foreign matter remaining in the equipment i.
When blow-down of the steam system is completed, equipment that was removed prior to the blow-down can be reconnected. Due to problems of condensation of steam or draining Checking the completion and effectiveness of steam blowing Target plates of aluminum or other metal will be located at the vent point during steam blowing.
A temporary movable silencer could be used to avoid exceeding noise level limitations during the steam blowing operation, if necessary.
Due to problems of condensation of steam or draining of condensate, this type of cleaning has to be used with the utmost care, as it can potentially create vacuum in the equipments being cleaned. Ideally, steam blowing should be done prior to the system being insulated to maximum the thermal cycling of the equipment.
The impact on the aluminum or other MOC target located at the vent point during steam blowing will be checked. Wherever allowed, only low pressure steam to be used if available at temperatures not exceeding C.
Steam Blowing Procedure Before putting steam into the system, the control valves, turbine meters, instruments, vacuum ejectors and strainers etc.Research paper on Analysis of Boiler losses to improve Unit heat rate of coal fired thermal power plant.
