BOILER SELECTION CONSIDERATIONS

For this reason, a watertube boiler is generally used if pressure above 350 psig design is needed. Firetube boilers are usually built similar to a shell and tube heat exchanger. A large quantity of tubes results in more heating surface per boiler horsepower, which greatly improves heat transfer and efficiency.

BOILER BASICS AND TYPES OF BOILERS, DIFFERENCES

By increasing the temperature and pressure of the hot water and increasing the size of the generators, some advantages are gained over the low pressure steam heating systems previously used. In other cases, special forced circulation boilers have been designed, which consist of many rows of tubes without a steam drum.

Superheated Steam Water Tube Marine Boilers

Marine boilers produce high pressure superheated steam to drive the turbines. The steam is generated by the water tubes which connect the water drum to the steam drum. Water and steam circulate through the vertical banks of tubes; the inner ones supplying the top drum and the outer ones dropping steam and water back to the water drum.

Proper Boiler Feed Water Temperature Management | Powerhouse

The difference between 140°F and 180°F in boiler feed water temperature equates to about a 3-4% difference in boiler efficiency. Feed water preheating typically occurs in either the feedwater tank or deaerator using supplementary steam.

The superheat temperature was regulated by changing the position of lit burners within the boiler, shutting off burners in the main furnace and replacing them with flames in the wing furnace had the effect of reducing the superheat temperature as the gasses are cooler when the reach the superheater bank.

What is the Temperature setting for hot water heating boilers

Boiler should be set at max temperature of 180 degrees for proper heating temperature. 120 degrees is temperature for domestic hot water, not heating temperature.

Boiler Introduction | CleanBoiler.org

In general, Scotch marine boilers are not used where pressures above 300 psig are required. Today, the biggest firetube boilers are over 1,500 boiler horsepower (about 50,000 lbs/hr). Firetube boilers are often characterized by their number of passes, referring to the number of times the combustion (or flue) gases flow the length of the pressure vessel as they transfer heat to the water.
