Due to the space combustion of natural gas, the boiler efficiency primarily depends on factors such as the size of the heating surface, the temperature of the heating medium, and heat exchange enhancement. Since natural gas boilers do not produce ash, the arrangement of the heating surface does not consider ash clogging and cleaning issues, allowing for the use of enhanced heat transfer methods like corrugated pipes and swirl vanes. As a result, the boiler has high thermal efficiency, with hot water boilers typically around 90%.

Due to the calorific value of natural gas being calculated at 8500 kcal/cubic meter, for instance, a 4-ton gas boiler has a thermal efficiency of 95%. A gas boiler that produces 4 tons of steam per hour, if fueled by natural gas, would generate 2,400,000 kcal of heat. The gas consumption would be 2,400,000 kcal divided by 95% divided by 8500, which equals approximately 297.21 cubic meters per hour. That is to say, the gas consumption for 4 tons of natural gas is around 297 cubic meters per hour. Of course, this is a basic estimate, as the actual gas consumption of the boiler depends on the efficiency of its operation. Zhenggu's efficiency can ensure at least 95%. In other cases, the specific factors at the operation site must be considered to determine the consumption.

Gas boiler gas consumption standards do exist; however, they are determined based on different gas usage conditions. In fact, this issue can be addressed during the boiler design phase, as the boiler design engineer can provide the answer. Factors such as boiler capacity, outlet water temperature, outlet pressure, steam temperature, and steam pressure all impact the final gas consumption of the boiler. Moreover, differences are even decided at the initial stage of boiler selection, as the boiler's inherent energy-saving capabilities can have a certain impact on the customer's actual gas usage.

The gas consumption index is not a vague concept; it requires specific analysis for specific issues. For example, with gas hot water boilers used in bath centers, different customers may require varying water output and temperature ranges for heating the water, which will increase the gas consumption during the heating process. Additionally, for boilers operating year-round, a balanced gas consumption is also necessary.

1. Condensing Boiler Structural Features

1. Boiler body structural features

   1、WNSLThe condensing series boilers feature a horizontal wet-back structure with the combustion chamber centrally located at a low position. The design incorporates a symmetrical distribution of heat exchange flues on either side, ensuring uniform and stable heat exchange loads. This facilitates even steam-water circulation on the working fluid side, significantly reducing the occurrence of water shortage accidents and enhancing the safety of the boiler.

   2The rational application of wave-shaped furnace tubes and threaded heat exchange elements not only enhances turbulent heat transfer of high-temperature flue gas but also effectively absorbs the thermal expansion and contraction of the furnace body.

   3The boiler is designed with a large furnace tube and large pot shell, featuring a maximum heating surface for complete combustion, minimal carbon accumulation, fuel savings, and significant characteristics such as high efficiency, ample power output, and strong overload capacity.

    3Our company, in coordination with the safety and economic aspects of natural gas combustion technology, has purchased multiple flue gas analyzers manufactured by the German company FISCHER. During boiler debugging and operation, these analyzers provide the combustion unit with reliable digital data on its actual operating performance. Adjustments to the combustion unit's air pressure and gas pressure are made based on the data provided by the flue gas analyzers to ensureCOAndO2Emissions are below the standard values, further ensuring high combustion efficiency and preventing waste.
