This document introduces the types and characteristics of steam boilers. Boilers can be categorized in various ways, and we explain the differences based on structure, regulations, the products they produce, material differences, and differences in heat sources and fuels. Additionally, we present the characteristics of different types of boilers, such as fire-tube boilers, water-tube boilers, and once-through boilers, highlighting their advantages and disadvantages. Please feel free to download and take a look.

• Boiler

This document explains the relationship between feed water temperature, boiler efficiency, and fuel consumption. It introduces the advantages of high feed water temperatures and provides formulas for calculating fuel consumption based on different feed water temperatures, including specific calculations for feed water temperatures of 15°C and 60°C. Additionally, it offers a detailed explanation of the "relationship between feed water temperature and boiler efficiency" and a "comparison of the impact of feed water temperature on boiler efficiency and fuel consumption." [Contents] ■ Changes in feed water temperature ■ Relationship between feed water temperature and boiler efficiency ■ Comparison of the impact of feed water temperature on boiler efficiency and fuel consumption ■ Considerations when introducing a boiler *For more details, please download the PDF or feel free to contact us.

• Boiler

This document introduces efficient operation of once-through boilers. The term "boiler load" represents the numerical value indicating how much of the boiler's capacity is being utilized, and it explains the most efficient load range using graphs. Additionally, it covers the advantages and pitfalls of low-load operation. Please download and take a look. 【Contents】 ■ What is boiler load? ■ Efficient "low-load operation" ■ Pitfalls of low-load operation ■ How to operate once-through boilers efficiently *For more details, please download the PDF or feel free to contact us.

• Boiler

"WILLHEAT" is a hydrogen-only small-scale once-through boiler equipped with a dry low NOx burner. We have successfully reduced the generation of nitrogen oxides (thermal NOx) without sacrificing boiler efficiency, which has been a long-standing challenge. The steam pressure fluctuation is ±0.005 MPa, and the steam dryness is over 99.8%. Please feel free to consult us when you need assistance. 【Features】 ■ Boiler efficiency 98% ■ Low NOx 60 ppm (converted to O2=0%) ■ Steam pressure fluctuation ±0.005 MPa ■ Steam dryness over 99.8% *For more details, please refer to the PDF materials or feel free to contact us.

• Boiler

"Willheat" is a small once-through boiler developed based on heat exchange technology, combustion technology, and pressure/water level control technology cultivated in large boilers. It achieves high durability, high-quality steam, high efficiency, and energy savings. An evolved high-performance package is available to support increased productivity. 【Features】 ■ Long lifespan ■ High dryness / Wide turndown ■ PID multi-unit control / Energy saving ■ Low NPx / Lightweight and compact *For details, please request materials or view the PDF data from the download.
