How to Choose the Right Industrial Gas Boiler: A Comprehensive Guide

Selecting the right industrial gas boiler is a critical decision that can significantly impact operational efficiency, cost effectiveness and environmental compliance. This guide can help you by outlining the important steps to consider during the selection process.

1. Understand Boiler Types

Commonly used boilers in industrial production include fire tube boilers, water tube boilers and condensing boilers. The following is an introduction to these boilers.

• Fire-Tube Boilers: Steam supply capacity is 1-20t/h. Suitable for small and medium industrial applications with low initial investment, very suitable for low pressure situations.

• Water-Tube Boilers: Steam supply capacity is 10-100t/h. It is suitable for industrial production with medium-high pressure and large steam demand, with high thermal efficiency, but the initial investment is relatively high.

• Condensing Boilers: Steam supply capacity is 1-20t/h. The heat recovery improves the thermal efficiency, is environmentally friendly and energy-saving, and is suitable for long-term operation. For enterprises with environmental protection policy requirements, this boiler is the best choice.

2. Analyzing steam demand

You need to choose the appropriate boiler product based on the actual needs of the enterprise, such as steam load, steam pressure, steam temperature, etc.

• Steam load: If your daily steam demand is between 3 tons and 5 tons, you can choose to install two 2-ton steam boilers and one 1-ton steam boiler. In this way, during the production process, you can automatically adjust the output load of the boiler through the modular system, save fuel, and maximize benefits.

• Steam pressure: In general, the boiler pressure must be sufficient to meet the required steam pressure for evaporation while compensating for any pressure losses in the piping or distribution network. For instance, if a process requires steam at 1.5MPa and there is a pressure drop of 0.2MPa in the system, the boiler should supply at least 1.8MPa. To ensure stable and safe operation, a safety margin of 25-30% should be added, meaning the boiler should be designed to provide a pressure of approximately 2.25MPa.

• Steam temperature: In the textile industry, dairy industry, food processing industry, pharmaceutical industry, etc., the process involved requires constant temperature and high temperature steam. Therefore, the stability of the boiler is of great importance.

3. Condensate treatment

Condensate recovery technology is widely used in industrial fields, such as power plants, chemical plants, food processing plants, etc. Especially in production processes that require a large amount of steam, the recycling of condensate can bring significant economic and environmental benefits to enterprises.

• Energy saving effect: Condensate condenses into water during the use of steam, but its temperature is still high, usually between 70℃-100℃. By recycling condensate, not only can water waste be reduced, but also a large amount of heat energy can be saved, reducing the fuel consumption required for boiler heating, thereby improving the overall thermal efficiency.

• Save water resources: After condensate is recycled, it can be directly used for boiler water replenishment, which can significantly reduce the consumption of fresh water sources, especially in areas with scarce water resources. In addition, the recycled condensate has good water quality and contains fewer impurities, which reduces the burden on boiler water treatment equipment.

• Reduce the use of chemical agents: Since the water quality of condensate is relatively pure, recycling condensate can reduce the use of deoxidizers and other chemical agents in boiler water treatment, reduce operating costs, and help reduce the risk of corrosion in the boiler system and extend the service life of the equipment.

4. Boiler system

At present, the top boiler manufacturers have equipped their boilers with intelligent systems, which can automatically detect the operation of the boiler, realize automatic water replenishment, overpressure warning, scale detection and other functions.

• Automatic water replenishment system: The automatic water replenishment system is one of the key functions in the intelligent operation of the boiler. When the water level in the boiler drops due to evaporation or other reasons, the system will automatically detect the water level change and replenish the water source in time to ensure that the boiler water level is maintained within the safe operating range.

• Overpressure warning function: Overpressure warning is one of the core protection measures for the safe operation of the boiler. When the pressure in the boiler exceeds the preset safety range, the system will immediately issue a warning signal to remind the operator to deal with it to avoid danger caused by excessive pressure.

• Scale detection function: Scale is a common problem that affects the thermal efficiency and safe operation of the boiler. The scale detection function equipped with the intelligent boiler system can effectively monitor the formation of scale in the boiler and issue a warning when the scale exceeds the standard.
