Value and function of Haoyu steam recovery machine

  The steam recovery machine is a system device that recovers a large amount of industrial water and steam generated after the use of coal and oil, releases part of the energy and forms condensate
The steam recovery machine condenses the steam into water through water cooling or air cooling, and then pumps it back to the boiler for heating and recycling
It can save the consumption of raw materials, that is, coal, oil, electricity and other energy, increase product quality, labor productivity, reduce human consumption, increase energy utilization efficiency and so on
According to statistics and analysis, assuming that the steam pressure of the plant is 7kg / cm2, the steam is transmitted to the heat engine through piping, and only 75% of the potential heat is absorbed; The remaining 25% of the heat is called waste heat, which is still left in the condensate and discharged through the drain valve
It is called condensate
If we don't try to recycle it and allow the precious condensate to be discharged into the ditch or become the atmosphere, it is a great waste for the company
Condensate value = raw water cost + soft water (Desalination) cost + deaeration cost + heat value 1
The condensate temperature is relatively high, the temperature of the production process can even reach more than 200 ℃, and the enthalpy value accounts for about 20-25 of the total enthalpy of fresh steam; 2
The condensate is high-temperature distilled water, and the condensate is high-purity water
After high temperature, the water quality has been - or equivalent to demineralized, close to pure water, and there are almost no corrosive gases such as oxygen and carbon dioxide in the condensate, without corrosion; 3
The condensate contains available residual pressure
In view of the value of the above condensate, the condensate recovery equipment developed by Haoyu has some functions
1
Increase the boiler feed water temperature and greatly reduce fuel consumption
2
There is no solid components such as boiler scale, which can save a lot of boiler cleaning expenses, water expenses and other corresponding expenses
3
Increasing the quality of boiler feed water can increase the steam quality, reduce boiler emission, save energy loss and reduce the cost of water treatment
4
The increase of feed water temperature and the decrease of oxygen content in water can avoid the corrosion of boiler, heat engine and piping
5
Increase the feed water temperature, reduce the temperature difference of the boiler air bag, reduce the thermal expansion and cold contraction of the steel plate, balance the pressure, and prolong the service life of the boiler
6
Condensate recovery can reduce the make-up water and greatly reduce the water treatment cost inside and outside the furnace
7
The water temperature difference between feed water and boiler is small, and the steam pressure is stable during boiler feed water
