Boiler Supplier

Finally, to increase the condensate drainage system. After completion of the work, the exhaust gas temperature of the boiler can be reduced to below 80 ℃. With reduce exhaust gas temperature, boiler efficiency of naturally increased. The reason for this comes from two aspects:

Recently, the party's fast Heli De H2800 boiler successful Jingdong headquarters procurement project. He Lide H2800 party fast adoption of new environmental protection industry leading combustion technology - premix combustion, fuel and air through precise regulation and control to achieve precise ratio, can ensure complete mixing of gas and air, burning more fully. The new technique Ultraten heat exchange elements - wings pipe, is a unique fast side. A unique built-tearing groove design, compared with ordinary heat transfer tubes, the heat transfer area can be increased 5-fold, greatly enhance the heat transfer rate, to strengthen the central flue of the disturbance, so that heat transfer efficiency is better, more energy efficiency .

Working principle Deaerator large steam boilers now use more and more, with respect to ancillary equipment for the boiler is the most important influence oxygen, so the knowledge deaerator to collect a bit, to tell you about : deaerator main role is to remove oxygen in boiler water and other non-condensable gases, in order to ensure the quality of the feed water. Flow of dissolved oxygen, the metal will be corroded in contact with water, while if the gas accumulated in the heat exchanger, the heat resistance will increase, reducing the heat transfer device. Therefore, any gas dissolved in water is unfavorable, especially oxygen, it will be a direct threat to the safe operation of the equipment. In the thermal power plant using thermal oxygen, oxygen itself is Water Heat System in a hybrid heater, around the same time hydrophobic chemical replenishment and plant-wide high-pressure water heater hydrophobic qualified high-pressure, exhaust etc. You can import deaerator be used, reducing the loss of soda plant. Headless deaerator works: primary condensate from the low pressure heater (including supplement water) by adjusting the control valve inlet into the deaerator, mixed with other hydrophobic brightest in the deaerator, via nozzles or a porous the discharge tube, a water film is formed umbrella, a hybrid heat and mass transfer and bottom-heating steam, water quickly reaches the saturated temperature at the operating pressure. In this case, most of oxygen and other gases in water are parsed substantially achieve the purpose of removing oxygen. The precipitated oxygen from the water and other gases are continuously removed from the outer tube with the top of the exhaust vapors deaerator. Entering the deaerator heater drain will also have a high portion of the water flashing steam as a heating steam source, all of the heating steam condensate after heat release of the condensed water, oxygen mixed with water flowing through the outlet down together. In order to make the water temperature in the deaerator operating pressure maintained at the saturation temperature, it can be heated by reboiler steam is introduced into the tube deaerator. Oxygen by water through the outlet pipe into the high pressure water feed pump booster heater.

These materials fall back down into the main furnace as well. These two components make up the primary recirculation loop. Bed media, fuel particles and ash escaping this primary collection mechanism will be collected using cyclone separators following the superheaters and delivered back the bed. This is the secondary recirculation loop. The boiler will be supplied with superheaters, economizers, refractory lined water wall and steam drum. Primary and secondary combustion air will be preheated by exiting flue gas following the economizer.
