Compared with the serious environmental pollution caused by coal-fired boilers, gas boilers are gradually popularized due to their unique clean and environmentally friendly characteristics. When selecting a gas boiler, the company chooses the appropriate one according to their own needs, which is a prerequisite for the good development of the company. Then, under the same heating demand, is it better to install a single large-tonnage gas boiler or to install two small-tonnage gas boilers?
Based on the analysis of the winter climate characteristics of the Chaoyang area in Beijing, we take a single large steam boiler 10 tons/hour and two small boilers 6tons/hour as examples.
November 1st - November 30th: average temperature -6~8°C.In general,the average temperature in January is the lowest, followed by December and February, and the average temperatures in November and March are higher.
First, the advantages and disadvantages of a single boiler (10tph).
1. The thermal efficiency is high (the boiler can reach more than 107%), and the heat transfer rate is fast.
2. The price is lower than the 2 sets small tonnage 6tph boiler.
3. There is a lot of fuel consumption.
4. If there is no backup boiler, once the boiler fails, the whole heating system will be paralyzed.
5. Power consumption of 10tph boiler’s auxiliary equipment (pump, water treatment, etc.) are more than of the 2sets small tonnage 6tph.
Second, the advantages and disadvantages of 2sets small boilers 6tph.
1. The number of running units can be flexibly adjusted according to the external temperature. When the weather is cold, the two units can be started at the same time. When the weather is warm, a single boiler can be activated.
2. The fuel consumption is lower.
3. Auxiliary equipment consumes less power.
4. The two boilers can be used as spares to ensure normal heating during the heating period.
5. The price of 2sets small boilers is higher than of a single large boiler.
6. The covering area of the boiler room will increase relatively.
In short, the single large-tonnage boiler and the two small-tonnage boilers mentioned above have their own advantages and disadvantages. When purchasing, the company must combine with its own actual situation, and negotiate with professional boiler engineers. After listening to the correct suggestions, the company can choose the boiler that is most suitable for enterprise development.
