The VAP-LN range from Babcock Wanson are high efficiency rapid Steam Generators designed to comply with the most restrictive international rules concerning NOx and CO emissions. Based on our proven coil design, VAP-LN provides a robust, energy saving and environmentally friendly Steam Generator that can produce steam from a cold start in as little as 3 minutes. High Efficiency Low water content means that start up is fast and heat loss and running costs are low. VAP-LN Steam Generators operate under very low thermal load conditions which results in a net thermal efficiency of more than 90%. When equipped with a Babcock Wanson flue gas economiser, thermal efficiency can be increased up to 95%. Simple Reliable Operation The VAP-LN Steam Generator includes a matched burner and a completely integrated and factory tested control system as standard and is fully packaged for simple site installation. Constructed with three full gas passes and a generously sized combustion chamber the VAP-LN design provides low thermal load, high efficiency and very low emissions.
