The application ratio of gas boilers is high. Due to the advantages of simple operation, high efficiency and environmental protection, it has almost replaced the previous solid fuels such as coal. Gas boilers can be divided into two categories: horizontal and vertical. What is the difference between a vertical gas boiler and a horizontal gas boiler? Let's learn about Fangkuai Boiler below.
To correctly distinguish between horizontal gas boilers and vertical gas boilers, it is necessary to understand their differences.
1. Different structure
Vertical gas boilers are "vertical" boilers. Horizontal gas boilers have a relatively large area, but are suitable for small layer spacing. Therefore, horizontal and vertical gas boilers are better, and it depends on which boiler is more suitable for boiler room design.
2. Different startup time
The steam generator has a simple structure, small water volume, and fast steam production; the steam boiler has a large water volume, sufficient output, strong load adaptability, and more stable long-term operation. Therefore, which is better, horizontal or vertical gas boiler, depends on the actual working conditions of the boiler. Under the same displacement, modular gas boilers are more suitable for small and micro users who use intermittent steam, such as ironing clothes, steaming rice, etc. Most industrial enterprises, such as chemical printing, dyeing, food heating, etc., require continuous and uninterrupted use of steam, and are more suitable for long-term stable operation of steam boilers.
3. Different steam quality
Horizontal gas boilers have steam drums to ensure the quality of steam, while vertical gas boilers cannot separate steam and water due to the lack of steam drums. The steam with more water leads to poor steam quality, and it is difficult to achieve the steam specified in the "General Technical Conditions for Industrial Boilers". quality requirements. In addition, the overall system of the vertical boiler is relatively compact, and the energy-saving equipment is not perfect. At the same time, the high moisture content of the steam is not conducive to the full utilization of heat, and the thermal efficiency of the boiler is low, which cannot play a good role in energy conservation and environmental protection.
4. The cost of water treatment is different
The normal water softener cannot meet the requirements, it needs to be treated with reverse osmosis water, and chemicals need to be added, which means that the investment cost of water treatment of the tubular boiler is high and the operating cost is high; and once the water quality does not meet the standard, it is easy to cause pipe burst and cannot be repaired. , The boiler as a whole is scrapped. The water quality requirements of horizontal gas boilers are relatively low. Referring to GB1576-2008 industrial boiler water quality standards, softened water treatment technology or resin filters are generally used.
5. Different capacity ranges
Vertical boilers are generally suitable for evaporation below 0.5t/h, while horizontal gas-fired boilers have a wide range of output from 1-110t/h.
