Selecting the right heat medium oil (also known as thermal oil or heat transfer fluid) for liquid phase heating systems is crucial for efficient and safe operation. Here are key factors to consider when choosing a heat medium oil:
Operating Temperature Range: Different oils have different operating temperature ranges. Choose an oil that can maintain stable thermal properties within the temperature range required by your system. Both the maximum and minimum operating temperatures are important t...
If the burner motor of a gas-fired boiler is not running, several issues could be at play. Diagnosing the problem involves checking various components and systems. Here are some common causes:
Electrical Issues: Check if there's an electrical supply to the motor. A tripped circuit breaker, blown fuse, or loose wiring could interrupt power supply to the motor.
Faulty Motor: The motor itself could be malfunctioning. Over time, motors can wear out or burn out due to electrical issues or mechanica...
Thermal fluid degradation or “burn-up” in a thermal fluid heater can be a significant issue that leads to the loss of fluid properties, system inefficiency, and potential equipment damage. Here are the common reasons why thermal heating fluid may degrade or burn up in your thermal fluid heater:
1. Overheating:
Exceeding the thermal fluid’s maximum recommended operating temperature can lead to ‘cracking’ or breaking down of the fluid. This may produce low molecular...
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.
The rated output of boiler refers to the maximum sustained output of industrial boiler under rated parameters (pressure and temperature) and certain efficiency. For steam boilers, the rated output is also called rated capacity, and the unit is t/h (tons/hour); For a hot water boiler, the rated output of the boiler is also called the rated thermal output, and its unit is MW.
MFT means the main fuel trip. To put it simply, when the protection signal is activated, the control system automatically cuts off the boiler fuel system and links the corresponding systems and equipment, so that the whole thermal system can be safely shut down, the boiler can be protected, and the fault can be prevented from further expanding.
Ash accumulation on the heating surface.
The scaling and ash deposition on the water-cooled wall of the furnace and the ash deposition of the superheater, convention tube bundles, economizer and preheater can increase the thermal resistance of the flue gas, weaken the heat transfer, lessen the cooling effect of the flue gas and increase the exhaust gas temperature of the gas-fired boiler.
Too high excess air coefficient.
Under normal circumstances, as the furnace outlet excess...
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.
