  • boiler selection considerations


    Flexible Watertube (Bent Tube) Boilers Flexible watertube boilers are a common type of boiler used for heating applications because of their resistance to thermal shock. Flexible watertube boilers are available in size ranges from 2 to 9 MMBtu/hr input. Flexible watertube boilers are available for low pressure steam or hot water applications.

    Continued heating creates steam bubbles in the front tubes, which are naturally separated from the hot water in the steam drum, and are taken off. However, when the pressure in the water-tube boiler is increased, the difference between the densities of the water and saturated steam falls, consequently less circulation occurs.

    Shell boilers are often operated with feedwater temperatures lower than 100°C. Consequently the boiler is required to supply enthalpy to bring the water up to boiling point. Most boilers operate at pressures higher than atmospheric, because steam at an elevated pressure carries more heat energy than does steam …

    Steam Heating Process – Load Calculating

    In general steam heating is used to. change a product or fluid temperature; maintain a product or fluid temperature; A benefit with steam is the large amount of heat energy that can be transferred. The energy released when steam condenses to water is in the range 2000 – 2250 kJ/kg (depending on the pressure) – compared to water with 80 – 120 kJ/kg (with temperature difference 20 – 30 o C).
