Two-pass vertical fire-tube steam boiler

Two-pass vertical fire-tube steam boilers are designed to produce steam with a temperature of no more than 120 ° C (due to the built-in superheater with an overpressure of up to 0.07 MPa (0.7 kg / cm2) in order to supply heat to technological processes in the production of: concrete goods, for steam heating, for steaming chambers, in the construction industry, in the food industry, in the production of corrugated cardboard, in the oil and gas industry, agriculture, for heat treatment of feed, pasteurization of milk, in the utilities, food and woodworking industries.

The boiler is supplied to the consumer partially disassembled, complete with mounting parts.

The boiler consists of:

Corpus;
Level gauge;
Water treatment unit;
Smoke exhauster;
Instrument panel;
Control panel;
Chimney sections;
Spark Arrester.

The technological process of vaporization is as follows:

Flue gases, passing through the gas path of the boiler, heat up its heat exchange surfaces. Water heated by heat exchange surfaces evaporates. The steam passing through the steam heater is overheated by the exhaust flue gases and enters the consumer. The resulting slags from the evaporation of water are periodically removed from the boiler.
