Industrial steam generators are used for many processes in the industry, such as generating hot water, bringing liquids to boiling point, evaporating products or drying systems, among others. Steam generators can be classified into two types, depending on the way they transmit heat:
Fire tube or smoke tube steam generators
These are generators in which the hot combustion gases are vp hr email lists conducted through metal tubes and on the outside these tubes are in contact with water, allowing heating until producing steam under the desired conditions. They are widely used in sanitary applications or in the agri-food industry.
These boilers are used when a low working pressure is required, less than 20 bars, and are suitable for industrial processes in general.
Water tube steam generators
In this type of steam boiler, the flame is in the internal space of the equipment, which is known as the hearth, and the water circulates inside the tubes so that the combustion causes the tubes and the water passing through them to heat up. The main components of an industrial steam generator are the burner, the water level control system, the pumps and the boiler body. The main characteristics of each are analyzed below.
Main components of an industrial steam generator
Burner
It is a device in which an electrical system produces a spark between the electrodes, using a high voltage, and after opening the way for the mixture of fuel and air, the combustion of the gas or liquid occurs. The burner assembly comprises several devices such as nozzles, electrodes, control systems and the burner barrel itself.
Water level control system
It is a safety and control system that checks that the water level inside the boiler is at a safe level and if the level drops, it sends a signal to the feed pump to inject more water. In the event of an operating anomaly, if the level continues to drop, it sends a signal to the burner to turn off, ensuring the safety of the equipment and people.
