Raising steam from a cold in a boiler

Fill water drum with hot dearated water, initial dosing can be given through the upper manhole cover which is then replaced. Keep the air vent open and fill water upto 1/3rd level in gauge glass or until it shows up in the gauge glass. Check fuel oil system and start circulating diesel oil. start FD fan and
purge the furnace properly. make sure that gauge glass coks are open and start firing the boiler with lowest firing rates. up-to 2.5 - 3 bar...we fire for 10 secs and stop for 10 mins... this is done upto 3 bar ... then close the vent... and then fire for 20 secs and stop for 5 mins..After reaching the working pressure drain the line and crack open the steam stop valve.

Why atomisation test should not be done in slide type fuel valves

Since very small needle lift is obtained in the test equipment result in an unequal pressure distribution in the cut off shaft resulting in a hard contact in a small area along with high frequency oscillations, low lubricity of test oil will increase the chance of seizure. Full lift and high lubricity of heavy oil eliminates this risk  of seizure during normal operation.( Always open and clean slide type valves before testing as cold sticky heavy oil along with small clearances can cause restriction in the movement of the spindle).

M/e trouble-what to check if Engine is not starting on air and fuel?

Engine not starting on Air: - * Low air bottle pressure or airline valve may be shut. * Air bottle isolating valve or automatic valve or distributor not functioning. * Control air valves faulty or less control air pressure. * Starting air automatic valve jammed. * Turning gear engaged. * Reversing has not taken place completely. * Control valve for fuel or start is not in its end position. * Bursting diaphragm(disc) on start airline damaged. * Fuel lever on maneuvering stand not on remote mode. * Auxiliary blower not running or not on ‘auto’ mode. * Emergency stop has activated. * Interlock is operated. *Cylinder air start valve defective or sticky. *Piston not in firing mode.   Engine not starting on fuel: - *Less fuel in service tank. * Fuel Oil filter is chocked. * Fuel Oil supply pumps not delivering required pressure. Or fuel pump tripped. * Puncture valve still active. *Fuel oil temperature to low. * Fuel level on local maneuvering stand, is not on remote stand. * Fuel rack...
