Furnace (steam generator) and a method for the combustion of fossil fuels with a high calorific value and low in the firing system the substoichiometric combustion.

摘要

Furnace (steam generator) with a vertical combustion chamber walls (2, 3, 4, 5) limited combustion chamber (1), with a fire space axis (vertical longitudinal axis), with a lower and an upper part as well as an upper end of the firebox (1) and with a flue gas outlet (ra) at the upper end of the firebox (1),in the lower part of the furnace chamber (1) the combustion chamber walls (2, 3, 4, 5), as screws tubing (s) and in the upper part of the firebox (1) the combustion chamber walls (2, 3, 4, 5) designed as a vertical tubing (v) as well as in the upper part of the furnace chamber (1) by convection heating surfaces (11, 12) are arranged,a combustion chamber wall (2; 3; 4; 5) a burner front wall (2) is,in the combustion chamber (1) a vertically and essentially perpendicular to the burner front wall (2) and to the opposite wall (3) extending central wall (9; 9a, 9b) and on each side of the central wall (9; 9a, 9b) in the burner front wall (2) at least one burner (7a, 7b) is arranged,..
