1. Air cooler/Air cooled heat exchanger
Product Description
An air cooler expertly utilizes ambient air as its cooling medium, efficiently sweeping across the exterior of finned tubes to lower the temperature or condense high-temperature process fluids within the tubes.
This compact, standalone equipment requires minimal footprint and offers flexibility in placement, suitable for both indoor and outdoor settings. It can seamlessly integrate with existing systems via hoses or steel pipes, while adjustable water pressure displayed on a pressure gauge ensures optimal operation. Close all cut-off valves of high-frequency equipment before use and ensure a clean system by draining water post-circulation to prevent debris-induced blockages.
Product advantages
1. Extend the lifespan of electronic tubes (high-frequency equipment): Unlike ordinary water that scales easily, requiring frequent cleaning, our solutions prevent scaling, thus enhancing emission power and longevity, and avoiding severe damage like anode burn-through.
2. Energy efficiency: For instance, a 100KW high-frequency electronic tube can reduce power consumption dramatically from 8KW with ordinary water to a mere 70W when using distilled water in the anode water circuit.
3. Minimize electrolytic corrosion: By reducing the current leakage to ground through water resistance, our solutions curtail electrolytic corrosion at electronic tube water jackets, with distilled water offering over 100 times less corrosion rate than ordinary water.
Product specifications and models
Fully customizable products to precisely meet your operational needs and specifications for optimal performance.
Product Usage
These systems are essential in the food industry for the cooling, processing, and freezing storage of meats, poultry, seafood, fruits, vegetables, dairy, and cold beverages. Additionally, they effectively support the cooling and refrigeration of alcoholic beverages like beer, as well as various industrial cooling requirements across chemical, pharmaceutical, mechanical, electronic, and hydroelectric sectors.
2. Air heat exchanger/Radiator
A versatile heat exchanger that effectively cools or heats air in motion using mediums such as water, glycol solutions, steam, or heat conduction oil. Selection of the appropriate model should consider actual operational conditions for optimal performance.
Air heat exchangers are categorized into air heaters and air coolers.
The air heater comes in various forms, including electric heating, steam heating, and oil heating, offering versatile options to meet diverse needs.
3. Economizer
Product Description:
An economizer is an ingenious device strategically installed at the lower part of a boiler's tail flue. Its primary function is to reclaim waste heat from exhaust gases, transforming boiler feedwater into a saturated heating surface under steam drum pressure. This remarkable process not only lowers exhaust gas temperatures but also maximizes energy savings and enhances efficiency, embodying the essence of an economizer.
The steel tube economizer, renowned for its flexibility, is not restricted by pressure and can even be used in a boiling configuration. Typically crafted from carbon steel pipes with outer diameters ranging from 32 to 51 millimeters, these economizers often feature fins to boost heat transfer efficiency. Characterized by horizontally aligned, parallel elbow pipes, sometimes referred to as serpentine pipes, the steel tube economizer exemplifies innovative engineering.
Product Advantages:
1. Harness the residual heat of low-temperature flue gas, effectively lowering exhaust temperatures, minimizing exhaust losses, and conserving fuel.
2. By pre-heating feedwater in the economizer before it enters the steam drum, the economizer diminishes the heat absorption demand on heating surfaces and offers a cost-effective alternative to more expensive evaporative heating surfaces.
3. Increased feedwater temperature as it enters the steam drum reduces the temperature differential across the drum walls, alleviating thermal stress and extending the operational lifespan of the steam drum.
Product Usage:
During the initial boiler start-up phase (specific to drum boilers), the absence of circulation in its steam water pipeline causes the boiler feedwater to remain stagnant, rendering the water in the economizer non-circulating. As combustion intensifies and flue gas temperature rises, there's a risk of water vaporization within the economizer, potentially leading to localized overheating. To prevent this, a supplementary pipeline from the steam drum's centralized drainage is connected to the economizer's inlet, establishing a recirculation pathway. This ensures continuous water flow, thus averting vaporization.
Production Process: Finned Tube Type
The economizer, meticulously positioned at the cooler end of the boiler, serves essential functions:
(1) By capturing heat from the low-temperature flue gas in the tail flue, the economizer successfully reduces exhaust temperatures in low parameter boilers, enhances the thermal efficiency of the boiler, and conserves fuel.
(2) The integration of economizers elevates the temperature of the water entering the drum, minimizing the temperature differential between the drum wall and feedwater. This reduction in thermal stress not only enhances the drum's durability but also extends its lifespan.
