SteamGen™ 4

SteamGen™ 4 is a horizontal single drum package boiler. For applications within the high-pressure industrial package boilers, we are proud to say that this is the best available technology on the market.

The best turn down ratio on the market
10 – 100 % load in 3 minutes. Low furnace load – low emissions

A SteamGen™ 4 solution applies where there is a demand for steam, power, or a combination of the two. Many industrial companies world-wide would benefit from this type of solution. SteamGen™ 4 is a horizontal single drum package boiler. For applications within the high-pressure industrial package boilers, we are proud to say that this is the best available technology on the market.

Before the single drum design was available, the industry standard was a technology, which had some obvious disadvantages. As the industry became more and more dependent on a reliable steam supply with higher efficiency, lower emissions, faster load change rates, decreased assembly time, and lesser maintenance, it was necessary to find a new approach to the overall basic design. SteamGen™ 4 combines all these requirements and adds to this several other features, which make the boiler even more superior.

Our design has several unique features: It is of a modular construction and fully-welded (no expanded tube to shell connections). It has water-cooled membrane walls and low furnace load and low emissions. There is a highly efficient and fast start-up and load change rate. The boiler is also fully drainable. Furthermore, it is easy to clean the heating surfaces and remove soot. The SteamGen™ 4 boiler is designed according to internationally recognized boiler codes such as PED/EN.
