Condensing Boiler Structural Features
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 a smooth water and steam 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 liners and reinforced heat transfer element threaded smoke tubes not only enhances the turbulent heat transfer of high-temperature flue gases but also effectively absorbs the thermal expansion and contraction of the furnace body.
3The boiler is designed with a large furnace tube, large shell, and large heating surface, ensuring complete combustion, reduced carbon accumulation, fuel savings, and notable features such as high efficiency, strong output, and excellent overload capacity.

2Increased with a proportional control instrument, the air pressure and its regulation further optimize the utilization of natural gas for enhanced combustion efficiency, eliminating the rough adjustment work associated with mechanical regulation.
3Our company, in conjunction with the safety and economic aspects of natural gas combustion technology, has purchased several flue gas analyzers manufactured by Germany's FISCHER Company. During boiler debugging and operation, these analyzers provide the combustion unit with reliable digital data on its actual operating performance. We adjust the air pressure and gas pressure of the combustion unit based on the data provided by the flue gas analyzers to ensureCOAndO2Emissions are below standard levels, further ensuring high combustion efficiency and preventing waste.

Description:
From the table above, it can be ascertained that,2ton/The current steam boiler, under full-load combustion, the condensing boiler can save more than the conventional type.17 m3/hNatural gas consumption, at the current market natural gas price3.8Yuan/ m3Calculate, save up to every hour64.6Yuan, a substantial amount.
From the table above, it can be seen that the condensing boiler produces more steam than the conventional type due to its high thermal efficiency, with nearly...10%This also demonstrates the positive effect of technological updates and improvements.
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 need to consider ash blockage 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 achieving around 90%.
Due to the calorific value of natural gas being calculated at 8500 kcal/cubic meter, for instance, a 4-ton natural gas boiler has a thermal efficiency of 95%. A boiler that produces 4 tons of steam per hour, if fueled by natural gas, would have a heat output of 2,400,000 kcal. The gas consumption would then be 2,400,000 kcal divided by 95% divided by 8500, which equals approximately 297.21 cubic meters per hour. This means the gas consumption for 4 tons of natural gas is around 297 cubic meters per hour. However, this is a basic estimate, as the actual gas consumption of the boiler also depends on the efficiency of its operation. Zhenggu's efficiency can guarantee at least 95%, while other factors must be determined based on the objective conditions at the operation site.
Gas boiler fuel consumption standards do exist, but they are determined based on varying gas usage conditions. In fact, this issue can be addressed during the boiler design phase, as the boiler design engineer can provide the answer. This is because factors such as boiler capacity, outlet water temperature, outlet water pressure, steam temperature, and steam pressure all influence the final fuel consumption of the boiler. Even the initial selection of the boiler can determine these differences, as the boiler's own energy-saving efficiency will have an 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 instance, with gas hot water boilers used in bath centers, different customers may require varying water output and temperature ranges from which to heat the water. This will, in turn, increase the gas consumption of the boiler during the heating process. Additionally, for boilers operating year-round, a balanced gas consumption is also necessary.
