Drum Type and Once Through Boiler Design

Once-through Boiler Characteristics. The once through boiler has high load response characteristics due to the fact that it does not have a drum and has a much lower water inventory. In the once through boiler, many times the load change response is dictated by the firing system and its controls rather than the boiler, per-say.

ONCE-THROUGH BOILERS

Once-through boilers are generally associated with high pressure operation and the feed water enters at high sub-critical (>180 bar) or supercritical pressure whilst superheated steam leaves at a pressure some 20–30 bar lower. Sliding pressure operation is adopted to accommodate requirements of …

Wiring Basics for Residential Gas Boilers

Oct 10, 2000· The load is now a boiler. (See Figure 4, page 20.) This wiring diagram shows 120 V coming from L1 of a circuit breaker, through a switch, powering a boiler control and returning through L2, back to the neutral bar of the circuit breaker box. This is fine if the boiler is 120 V. However, most gas boilers you will be working on have 24-V controls.

Why Once Through Boiler | Once Through Boiler

The fire tube boiler will run both units (12 ton/h) while Once Through Boiler will run three units (9 ton/h) and have the fourth unit available as required. Since Once Through Boiler can operate from a cold back-up, (water to steam in 5 minutes, while the fire tube boiler can take hours), the fourth unit can be idle until needed.

Once-through boilers are able to produce steam at higher pressures and temperatures than drum boilers. In thermal power plants, raising steam conditions (pressure and temperature) can enable efficiency gains in power generation equipment, allowing an operator to reduce its fuel consumption and CO 2 emissions.
