Description

one

The invention relates to boiler units.

According to the main author. St. No. 300705 is known for a fire-tube-gas boiler with a turning chamber and a contact-foam economizer adjacent to the rear wall of the chamber from the outside.

The aim of the invention is to obtain hot water that does not contain harmful impurities.

This is achieved by installing heating surfaces in the contact economizer and in front of it.

FIG. 1 shows the proposed boiler, longitudinal section; in fig. 2 - the same, section A - A in FIG. one; in fig. 3 - heating surface, general view.

The boiler has a cylindrical body 1 with a flame tube 2 and smoke tubes 3 and 4, welded into bottoms 5 and 6, a burner 7, a front 8 and a rear 9 swivel chambers, water-cooled partitions 10 welded to a removable wall 11 of the rear swivel chamber 9, contact - economizer 12, chimney 13 and heating surfaces 14 and 15, the first of which is installed in economizer 12 and the second in front of it. In the rear wall 11 of the turning chamber 9, windows 16 and a flap 17 are provided. To prevent flue gases from passing past economizer 12, two overlapping openings 18 and 19 are provided.

The flue gases from the flame tube 2 pass t the rear turning chamber 9, the first beam of fire tubes 3, the front rotary chamber 8, the second beam of fire tubes 4 and through the windows 16 in the wall of the rear slewing chamber 9 fall into a foam-economizer 12 and from it - into the chimney 13.

Cold water, heated by direct contact in the foam layer with flue gases ("contact water"), is supplied to the upper part of the foam-and-gas economizer having a common wall with a rear swivel

chamber 9. The heat from the foam layer is removed to a large extent by the coil heating surface 14, and also due to some consumption of contact water, which is poured into the cooled back walls 10

pivoting chamber 9 out of the foam layer, which is then discharged into a collection tank.

From the heating surface 14, the water is heated to the temperature of the wet thermometer to the surface 15, where it is heated to a higher temperature. If necessary, the temperature of the water leaving the surface 15 can be increased by passing more hot gases from the rotating chamber 9.

with the help of a damper 17. Subject of the invention I. The fire tube gas tube boiler according to ed. St. 300705, characterized in that, in order to obtain hot water, which does not contain 5 harmful impurities, a heating surface is installed in the economizer. 2. The boiler according to claim I, characterized in that an additional heating surface is installed in front of the economizer.
