ATTSU - Model S - Horizontal Hot Water Boiler
From Hot Water Boilers
The boiler S is a horizontal hot water boiler, firetube, three pass boiler with reverse flame and smoke chamber completely cooled by the water in the boiler. This boiler is specially designed for use with biogas. With Thermal power 200-3500 kW and design temperature to 110 ° C. The construction of the S series boilers guarantees high output and efficiency at low flue gas temperatures, this ensuring reduced polluting emissions.
The main technical elements of the design are:
- The careful design of the shapes, to ensure an optimum ratio between the combustion volumes and the heat exchange surfaces - the choice of materials used, for the long life of the boiler. The boilers feature pressurized combustion, with three flue passes, a horizontal-cylinder configuration and flame reversal in the furnace, completely cooled; the flame produced by the burner is reversed peripherally towards the front, where the flue gas enters the tube bundle,featuring turbulators to create a swirling path that increases the heat exchange by convection.
- On leaving the tube bundle, the flue gas enters the rear chamber and is transferred to the chimney. The boilers are fitted with a door featuring hinges that can be reversed for opening to the right or the left, and is adjustable in both height and depth. The body plating is insulated with a thick layer of glass wool, and covered with a further layer of tearproof material. The external finish consists of painted steel panels. The hoisting hooks are fitted on the top of the plating.
