Pressure gauge’s installation of coal fired boiler

Certain working pressure exists in the design of coal fired boiler,the function of which is telling the enterprises using coal fired boiler to operate according to the rated working pressure,so,pressure gauge’s installation is needed in the using processing of coal fired boiler.ZG boiler,as a professional manufacturer of coal fired boilers,to improve the quality of service,gives the following good service of processes of pressure gauge’s installation.

1.The pressure gauge should be equipped with trap,which can condense the steam in the trap,avoiding the deformation of the elements in the table because of the high temperature steam entering the bourdon tube .When trap uses steel tube,its diameter shall not be less than 10mm,to clean,chang and check the pressure gauge easily,the three-way cock should be installed between the pressure gauge and the trap.

2.Each coal fired boiler must install the pressure gauge contacting drum steam space directly,so,the pressure should be installed before feed-regulating valve,at the outlet of separable economizer and between the superheater’s outlet and the main steam valve. According to the maximum allowable pressure of the coal fired boiler,the red alert line can be marked on the dial of the pressure gauge,but,it should not be drawn on the glass of the pressure gauge,to avoid causing the illusion because of turning.

when coal fired boiler installs pressure gauge,besides the above,ZG boiler also indicates that adequate lighting is needed to observe and check easily for the operators,at the same time,we should prevent the effects of radiant heat,low temperature and vibration.
