here some more facts about the Multi Fuel Burner MB 10/18.
The burner was built in the 80ies of last century by WEBASTO for field kitchens and manual operating. Its maximal output is 30.000 kcal (34,9 kWh), so one suits for small steam plants up to 3,5 kW (4,75 Hp) (10% thermal efficiency). It is a pressureless one.
