Water Tube Boilers | Spirax Sarco

Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1) it is easy to see that because the tube diameter is significantly smaller much higher pressures can be

The system of tubes that surrounds the furnace are known as waterwall or floor tubes. The feed water gets heated when passed through these tubes. Addition to this there are Large-bore downcomer tubes that passes outside of the furnace and are used to circulate water between the drums to which the tubes are attached from outside of the furnace.

Fix Heating Zone Circulator Pump that runs constantly when ...

Hot water could be circulating by convection thus also causing the boiler to run as cooler water returns to the boiler by convection. It's easy to check this. Turn off power to the circulator pump (but not the boiler). If baseboards or radiators still are getyting hot AND the thermostat is not calling for heat (or has been disconnected entirely) then

Apr 26 2007 · pump (circulator) on a hot water heating system has the same function as the fan on a forced air heating system. We are pushing the heat transfer medium (water) from the boiler out to the rooms we want to heat. Just like the fan on a forced air system the pump pushes the heated water out to the system and pulls the cool water back.
