High Efficiency Electrical Steam Boiler for Sale "Future" Electrical Steam Boilers have the higher thermal efficiency while radiation loss is minimal. With a carefully calculated heat to steam ratio, operating pressure is achieved quickly with maximum efficiency.
Spacing in the first superheaters can be from 150 to 1000 mm. Superheaters are the hottest heat transfer surfaces in the boiler, so they are often built with temperature-resistant alloys. As these superheaters operate at flue gas temperature ranges of 800–1200°C, they often need to be built with corrosion resistance in mind. High-grade materials are expensive and require special welding techniques and often heat treatment.
