Steam quality is an important indicator for measuring the overall quality of a gas-fired steam boiler. This is because many companies purchase gas-fired steam boilers directly using steam. If the steam quality is not high, it is likely to affect the entire production of the project. Process and the quality of the final manufactured item. So, how do enterprise users choose a gas-fired steam boiler with good enough steam quality?
1. Cleanliness of gas steam boiler
There may be rust and carbonate deposits in the steam pipeline, and there may be residual welding slag and sealing material fragments during installation. These impurities will cause blockage and damage to valves and equipment, and will also increase pipeline wear. The way to improve cleanliness is to equip gas steam boilers with pipe filters to deal with these impurities in real time.
2.Dryness of gas steam boiler
Factors such as improper water treatment for gas-steam boiler water treatment, irrational boiler level control, and excessively high peak loads for a short period of time will cause the phenomenon of co-transpiration of the boiler, causing the boiler outlet to carry boiler water. When the steam moves in the pipe, the heat dissipation of the pipe will cause a part of the steam to condense, adding condensed water in the pipe. Adding a steam-water separator is a useful way to improve steam dryness. An efficient steam-water separator can improve steam dryness to 98%.
3.Purity of gas steam boiler
There will be air in the steam system. This is because the steam generated in the boiler still inevitably contains a small amount of air. In addition, there will also be air when the pipes and equipment are started. When the system and equipment are stopped, the air is sucked in due to the internal vacuum.
Air has a low thermal conductivity and is a poor conductor of heating. The steam system contains air, which will reduce the production capacity of steam equipment, and also increase the corrosion of pipelines, valves and equipment. The most useful way to eliminate non-condensable gases such as air in the steam system and improve the purity of the steam is to install an automatic air exhaust device in the system.
