The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.

Advantage Of Once Through Boiler


"Energy Saving by Introduction of High Efficiency Once-through Boiler"The advantage of once-through boiler (project boiler) is that its high efficiency can be maintained under the low range of operation load. On the other hand, efficiency of oil and gas-fired fire tube boiler is low at the smaller operation load range. Figure 1 shows the MIURA SINGAPORE – Japanese Leading Company of …In a once-through boiler, prior to firing, sufficient flow is required through the boiler pressure parts which are exposed to high gas temperatures during start-up. With smooth furnace tubes, a minimum flow at 25 percent of full load flow generally represents a good balance between furnace tube cooling requirements over the load range and furnace enclosure pressure drop.
