Well-designed:

Horizontal inline three-return full wet back design100%Wave-shaped furnace tube,Excellent thermal expansion properties. The water-in-fire overall design, with ample heating surface area and rational structural arrangement, ensures the high efficiency operation of the boiler. 

High-efficiency energy-saving:

Steam and hot water boiler series feature high thermal efficiency of97%-99%With a large combustion chamber and reasonable structural arrangement, more heat can be transferred into the water, greatly enhancing the heat exchange capacity between fuel and steam, as well as between fuel and hot water. 

Meets environmental protection requirements:

The combustion chamber is spacious, fully utilizing radiant heat transfer, and complemented by a high-quality and reliable imported burner, ensuring complete combustion of the fuel and significantly reducing the emission of harmful components in the flue gas. Our company's fuel (gas) steam and hot water boilers have been tested by authorized departments and meet national environmental protection requirements, making them ideal eco-friendly products. 

Superior configuration:

Complementing world-renowned burners, the advanced control system (with mainly imported components), valves, and pumps all utilize national-quality products. The superior boiler accessory configuration ensures robust support for the safe and stable operation of the boiler. 

Fully automatic operation:

Users simply need to press the start button, and the boiler will operate according to the set program. Load regulation, water supply, and other functions are all fully automated, requiring no constant supervision. 

Ease of maintenance and repair:

Boilers are equipped with movable ash box doors at both front and rear. The rear features a fire observation hole and inspection holes, allowing for entry into the furnace chamber for inspection and cleaning. The boiler body has a manhole, with the structural design thoroughly considering ease of maintenance and future repairs.

Steps and Standards for Water Quality Testing of Gas Boilers

Determination of Chloride Ion Content

Measure 100ml of boiler water into a 250ml conical flask, add 2-3 drops of phenolphthalein indicator, which should turn pink. Then titrate with sulfuric acid until colorless. Add 2-3 drops of potassium ferricyanide indicator and titrate with silver nitrate standard solution until a date-red color is obtained. Record the volume of silver nitrate consumed, multiply by 35.5 to obtain the standard for chloride ions: chloride ions ≤ 400.

Determination of Alkalinity

Measure 100ml of boiler water into a 250ml conical flask, add 2-3 drops of phenolphthalein indicator, the solution turns pink. Titrate with the standard sulfuric acid solution until the color just fades, then add 2-3 drops of methyl orange indicator and continue titrating with sulfuric acid until the solution turns orange-red. Record the volume of sulfuric acid consumed; this value is equivalent to the alkalinity.

Measurement of 3 Hardness

Pipette 100ml of boiler water into a 250ml conical flask, add a few granules of Loheng T indicator, then add 2-3 drops of ammonia-ammonium chloride buffer solution. Titrate with EDTA standard solution until the solution changes from wine red to blue, noting the volume of EDTA solution consumed. This volume is equivalent to the boiler water hardness value.

Standard: Hardness: less than or equal to 0.03 mmol/L for steam generators

Hot water boiler: 0.6 mmol per liter

Determination of pH Level

Determine pH using pH test strips

Standard: pH Value: 10-12
