Thus, a boiler operation at high pressure will require less heat addition for steam generation. 3.1 Features of High pressure Boilers High-pressure boilers have the following features: Forced circulation of water - in all modern high-pressure boilers, the force circulation of water is maintained with the help of pumps.
Another possibility for chemical carryover is that you are dropping too big of a load too fast onto the boiler which drops boiler pressure suddenly causing the boiler to suddenly boil excessively and carrying over into the steam line. This is a bit harder to fix but can be done. Now, the gauge glass problem!
Another reason to replace an AJAX boiler is to take advantage of rebates and incentives to install high efficiency boilers. Since boilers - like all large industrial or commercial assets - eventually need to be replaced, taking advantage of rebates or beginning to realize cost savings are reasons to consider sunsetting your AJAX boiler.
3.0 Pressure Vessel Construction: The semi-wetback design will provide for boiler tube removal through the front or rear doors. 3.1 The pressure vessel is built in strict accordance with ASME code section and to latest year of issue and addendas.
Blowdown in Boiler Definition. Blowdown in Boiler, Usually, water which is fed to the boiler contains high Total Dissolved Solids (TDS) content as well as other dissolved and undissolved solids in it. On heating water or converting water to steam, these dissolved solids do not evaporate and gets separated from water or steam and settled at the bottom of the shell.
This is especially true in high-pressure boilers, which require a high level of quality water. Using standard calculations can lead the surveyors to an incorrect number.
4) Once the boiler is started the steam pressure will start rising and when it crosses 3-4 Kg/cm close the by-pass valve and let the boiler develop pressure to the maximum set pressure i.e. 10 Kg/cm. 5) The boiler will automatically stop at the set pressure by the high steam pressure switch. 6) Min valve should be opened slowly so that pressure
1 Power boiler − a boiler in which steam or other vapor is generated at a pres-sure of more than 15 psi (100 kPa) for use external to itself. 2 Electric boiler − a power boiler or a high−temperature water boiler in which the source of heat is electricity. 3 Miniature boiler − a power boiler or a high−temperature water boiler in
Pressure vessels with quick-opening doors command a great deal of respect from the Boiler Inspection and Insurance Company of Canada (B.I.& I.). We know by simple calculation that a pressure vessel eight feet in diameter with working pressure 150 psi, has an end force of just over one million pounds acting on the heads.
A high pressure boiler plant of 51 to 500 horsepower is exempt from the high pressure attendance requirements of item A if the plant is operated at low pressure. All boilers must either be shut down or shifted to low pressure. If a boiler is shifted to low pressure, it must have the following controls, safety devices, and conditions: §
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low

In addition to the operating limit control, each steam boiler shall be provided with a high limit pressure-actuated control which by interruption of an electrical circuit will automatically stop the heat generating apparatus if the steam pressure rises to five pounds psi gage above the maximum allowable working pressure of the boiler.
Tighten all covers such as manholes, hand holes, inspection doors, etc. during the pressure rising period. If required, check all flange joints on the plant. Change to automatic control of the burner when the boiler pressure is 0.5 bar lower than the working pressure of the boiler.
Superheaters in boilers have all modes of heat transfer in boiler. They also have a very high length through which the total pick up steam temperature takes places at each unit length. The length of tube and temperature pick-up needed to raise the steam to the required level of super heating calls for using different materials along the total length.

The high pressure feed water is supplied to the boiler through this valve. This valve opens towards the boiler only and feeds the water to the boiler. If the feed water pressure is less than the boiler steam pressure then this valve remains closed and prevents the back flow of steam through the valve.
