Boiler antifreeze, as its name implies, is a kind of regulator that can prevent the water in the boiler or boiler circulation pipe from freezing and inhibit the formation of scale. Boiler antifreeze contains a special corrosion inhibitor, which can be used and stored for a long time, keeping its characteristics unchanged, and will not damage the metal parts of the boiler.
Different boiler parameters have different requirements on the PH value of boiler water. Generally speaking, the PH value of boiler water is basically between 10 and 12, in some cases, the PH value is between 9 and 11.
Prepare relevant technical data, including technical data of boiler manufacture and installation, boiler use registration data, boiler operation records, water quality test records, repair and modification records, accident records and previous inspection reports;
Hot-water boiler is a kind of thermal equipment that uses the heat energy released by fuel combustion or other heat energy (such as electric energy, solar energy, etc.) to heat water to the rated temperature. According to different fuels, hot water boilers can be divided into gas-fired hot water boilers, oil-fired hot water boilers, biomass-fired hot water boilers, and coal-fired hot water boilers. How to choose hot water boiler? We will focus on the heating, pressure and thermal efficiency of hot water boiler.
Power boilers take the chemical energy stored in fuel, convert it to heat energy in the combustion process, and transfer that heat energy to water to produce steam. The transfer of energy from combustion gases to the water and steam is called heat transfer.
Water treatment outside the boiler
Before entering the boiler, raw water is treated with water treatment equipment to remove impurities such as hardness, salinity, dissolved oxygen, etc., so that the feed water can meet the water quality requirements specified by steam boiler. Common water treatment equipment includes sodium ion exchange water softening equipment, ion exchange desalination equipment, reverse osmosis water purification equipment and thermal oxygen removal equipment.

In boilers, economizers are heat exchange devices that heat fluids, usually water, up to but not normally beyond the boiling point of that fluid. Economizers are so named because they can make use of the enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler, thereby recovering more useful enthalpy and improving the boiler's efficiency. They are a device fitted to a boiler which saves energy by using the exhaust gases from the boiler to preheat the cold water used to fill it (the feed water).
A cornertube boiler is a type of natural circulation water-tube boiler which differentiates itself from other water tube boilers by its characteristic water-steam cycle and a pre-separation of heated steam from the steam-water mixture occurs outside the drum and the unheated downcomers.
