Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power ships.They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary boiler.

Boiler pressure is one of the most common faults associated with the heating system, however there is an easy fix. When the heating system is cool, the pressure should be between 1 and 1.5 bar on the pressure gauge. Watch our video on how to repressurise your system here.
You should only have to increase the boiler pressure once or twice a year. But, if your boiler keeps losing pressure this could mean that the water from the system is leaking. Please always contact a Gas Safe engineer to repair the boiler if you spot a leak - you can find an engineer near you with Gas Safe's - Find An Engineer Tool.
Seven Telltale Signs Your Boiler Needs to Be ReplacedIt is not uncommon for property owners or facility managers to wait until a boiler completely breaks down before replacing the unit.To make things worse, these types of failures happen when there is real need for heat (for instance, a very cold day) and since the failure is unexpected, there are rarely emergency funds allocated to fix the
Following the recommended schedules will help avoid common issues like spalling from high-pressure steam as it builds up within the replaced refractory lining. While in the past, dry-in schedules were generally about 72 hours, end users today only have to wait about 24 hours before they can activate the boiler.
How to Know If a Propane Gas Regulator Is Working Properly. Propane storage tanks for stoves, furnaces or grills have a high internal pressure far greater than the pressure a propane appliance needs.
Modern boilers require constant water pressure in order to function properly. A boiler that keeps losing pressure is therefore always cause for concern. It is important to investigate and identify the cause as soon as possible, to protect the boiler itself and also your home from any risk of damage.
As furnace pressure increase is one of the indications for boiler explosion boiler operating engineers and all concerned must view increase in furnace pressure very critical and take corrective action and ensure safety.

Low Water, High Risk. What happens in a high-pressure steam boiler when the water level gets too low and the burner does not shut off? The answer, "It depends," may be surprising. Low water conditions can cause a range of damage. On one end of the spectrum is a short-term condition that results in little or no visible damage.
HVAC Troubleshooting Commercial heating, venting, and cooling systems do more than simply regulating the temperatures in the building. If there is a defect in a commercial HVAC system, it can affect the satisfaction and health of the occupants, the productivity level, and the energy bills.
However, since the pressure went too high - ~3 bar - the boiler opened its safety Pressure Release Valve and 'dumped' the excess water out the copper discharge pipe. What that then means is that there's less water in your system than before, so when it cools down again the pressure will drop to below the original 1 bar 'cold' level.
Low Pressure Boiler Engineer: Steam boilers operated not in excess of 15 psi and water boilers operating not in excess of 50 psi and 250° temperature. Third Class Boiler Engineer: Steam boilers operated not in excess of 150 psi and water boilers operating not in excess of 160 psi and 350° temperature and 150 horse power.
