In industrial production, steam, as an extremely versatile and important energy source, is almost inextricably linked to all enterprises. A large amount of industrial water and energy sources such as coal and fuel oil are used to generate steam, and the thermal energy of steam is utilized to achieve industrial production processes. However, the condensate water generated after steam releases part of its thermal energy is often discharged directly. Condensate water, after softening and desalination treatment, is very pure and contains a large amount of heat, generally accounting for about 20-30% of the total heat of steam, and in some equipment, it can reach up to 40%. Therefore, if high-temperature condensate water can be recycled as boiler feedwater, not only will industrial water be saved, but a significant amount of fuel will also be conserved. In this way, when producing the same amount of steam, the boiler can save 20-40% of fuel, water, and water treatment chemicals. Fuel savings also lead to a reduction in boiler flue gas emissions, thereby protecting the environment. If energy conservation and environmental protection are placed in the **first position, condensate recovery is the key to ensuring cost reduction and efficiency improvement in factories. Most enterprises adopt traditional open recovery systems in condensate recovery systems, where the condensate collection tank is open-type, allowing condensate water to be exposed to the atmosphere. Due to pressure drop flash evaporation, a large amount of secondary steam is generated, resulting in the loss of most of the heat, and the recovered water temperature is below 100°C, with minimal heat recovery.

Currently, the issues faced in domestic steam recovery mainly include: failure to fully and reasonably utilize the thermal energy of high-temperature saturated condensate water, inability to overcome severe pump cavitation, pump failure to draw water, frequent occurrences of vapor lock, water hammer, uneven pressure, inability to recover water, frequent breakdowns of steam pumps, and frequent shutdowns for maintenance.   Therefore, our company primarily promotes fully enclosed condensate recovery devices, equipped with Taiwan multi-stage high-temperature water pumps (which operate stably below 200°C water temperature, without cavitation, and are durable), and configured with saturated condensate pressurizers, ensuring smooth overall operation of the recovery equipment, minimal maintenance, and maximum guarantee of hot water recovery! It directly sends high-temperature water of about 150°C into the boiler, ensuring that the entire process from steam being sent from the boiler to becoming high-temperature condensate water after passing through steam-using equipment and then being returned to the boiler operates in a fully enclosed system without contact with the external environment, *maximizing the reduction of water loss and heat loss, saving fuel, and reducing costs!      

I. Characteristics of Fully Enclosed Steam Condensate Recovery Equipment:   

1= The recovered condensate water does not come into contact with external air, reducing the chance of re-dissolution of oxygen and carbon dioxide, thereby minimizing oxidative corrosion of equipment;

2= *Maximizes the reduction of water and heat loss, fully utilizes the thermal energy of high-temperature (140-180°C) return water, directly sends it back to the boiler, saving fuel by (10%-30%);  

3= Its design is scientific, reasonable, concise, and smooth, with a small size and minimal space occupation. The equipment has been used by over a thousand customers for more than twenty years, with mature production processes and leading technology, ensuring no worries!   

4= Utilizes Taiwan multi-stage high-temperature water pumps, ensuring reliable performance; equipped with specially designed saturated condensate pressurization devices, ensuring smooth pump operation, no cavitation, absolutely no water leakage, and minimal maintenance;   

5= Independent/automatic control system, stainless steel electromagnetic flap-type water level control system, dual overpressure automatic discharge (electromagnetic + mechanical) for enhanced safety;    

6= As indicated by the boiler feed pump water addition time, it significantly reduces boiler water usage, saving expenses;   

7= Extends equipment service life, reduces the operating time of pumps, fans, water treatment systems, and heaters, resulting in noticeable energy savings.  

8= Equipped with a siphon device, allowing steam to be recovered as well, ensuring smoother high-temperature water return.

II. Energy-Saving Principle of Fully Enclosed Steam Condensate Recovery Machines:

Under normal pressure, 1 kg of water at 20°C absorbs 80.08 Kcal of heat to rise to 100°C, after which the temperature no longer increases, and instead, it begins to vaporize. To completely convert 1 kg of water at 100°C into steam, 539.06 Kcal of heat is required. The heat required for the water to rise in temperature is called "sensible heat," while the heat required to convert water into steam is called "latent heat."       

In actual production, when saturated steam is delivered to steam-using equipment, through heat conduction, the latent heat decreases, and the steam turns into condensate water, while the pressure also drops (due to sensible heat loss). High-temperature condensate water containing a large amount of sensible heat is discharged through high-pressure steam traps. If it is directly pumped into the boiler via the high-temperature water pump of a closed recovery device, only the consumed heat needs to be replenished before it can be sent back to the steam-using site for use. Water loss and heat loss (pipeline and equipment heat dissipation are minimal!) If the condensate water is recovered by an open recovery device, due to a significant pressure drop, a large amount of sensible heat is released, and latent heat suddenly increases, causing part of the water to vaporize and discharge, taking away about 30% of the heat contained in the condensate water, resulting in significant waste of water and thermal energy! At the same time, it causes the water tank temperature to be too high, leading to issues such as pump failure to draw water, prolonged pump operation, and pump damage.
