Boiler

Condensing a portion of the air preheater and use of double combination economizer design. Internal economizer heat exchanger elements using the new technology - the wings of the tube instead of finned tubes, a five-fold increase in heat transfer area at the same volume, latent heat of vaporization of the portion of the flue gas is sufficiently absorbed, effective utilization of the fuel energy, energy saving at the same time enhance the efficiency of the use of the boiler. Air preheater is further absorbed by the air and the flue gas convection heat latent heat of flue gas, and the air heated by the air preheater is connected directly into the burner tube, providing warm air for the fuel, thus improving combustion efficiency. This exhibition brings Chinese fast "Euromonitor" series boilers attracted a large number of customers, to give customers unlimited. Here, fast Boiler staff wish the exhibition every success.

This method is a method of adding a base, so that the boiler is filled with water PH value of 10 or more. Corrosion resistance of the metal surface to generate a protective film to prevent corrosion of metals in dissolved oxygen. The lye used as NaOH, Na3PO4 or a mixture of both.

Scale chemical plant boiler scale formation of harmful chemical hazards boilers formed in the boiler 1, the boiler steel pipe is due to overheating burning boiler known as sources of hazards, the key is the thermal conductivity of the boiler very poor. Thermal conductivity material size generally used to measure the thermal conductivity, thermal conductivity smaller scale than the boiler plate several tens to hundreds. When the size of the enemy boiler heating surface, heat transfer conditions deteriorate, so that fire and smoke tube well water can not absorb heat, the surface temperature of the heating, the metal strength, easily lead to the boiler tube expansion, deformation and burst pipes. Further, after the furnace tube fouling cross-sectional flow area decreases, resistance increases circulation, and disruption of normal cooling water circulation of the boiler, resulting in the loss of the combustion furnace tubes. 2, the boiler output decreased fuel waste is contaminated when the boiler, the boiler heating surface heat transfer becomes poor, the exhaust gas temperature will rise. Since the scale low thermal conductivity, hindering heat transfer, thereby reducing the thermal efficiency of the boiler, fuel consumption increases, reducing the yield of the boiler. Experimental proof for a working pressure of 1.3 MPa boiler scale mixing to form 1mm thick, wasting fuel may be 5% to 8%. 3, increase the amount of maintenance the boiler and endanger the safety of the boiler heating surface after scaling is very difficult to remove, the need to frequently clean dirt or boiler pickling, and pickling boiler is likely to cause corrosion to the boiler, while the pickling liquid waste to the environment caused by emissions pollution not only damages the boiler life, but also requires a lot of manpower and material resources for maintenance, and threaten personal safety, the safety impact of the production.

Gas hot water boiler safe operation Code: People can not do without domestic water heating and gas hot water boiler, due to the special nature of the performance of the need to comply with strict safety operation of the Code. Then, gas hot water boiler needs to run how to protect their safety performance? 1, after carefully checking gas hot water boiler water supply, drainage, gas pipe fittings, safety valve, pressure gauge, water level gauge is sensitive Haoshi before work, make sure it is safe to operate. 2, with both hands to manipulate when Sheung hand to open the door of water, whereupon the other hand the water injector and valve open, water flows naturally into the furnace. When stopped, the steam valve should be closed first, then turn off the water door, switch and valve, the front face must escape in order to avoid accidents caused by soft drinks out. 3, gas hot water boiler in operation, to pay attention to all parts of the check, and observe whether the water pressure in the normal range. Fireman can not leave their posts without permission, when night work, avoid dozing off, but not allowed to sleep, to avoid accidents. Boiler blowdown, a class must be properly adjusted before the sewage water level, slightly higher than the normal water level of 2/3 of the standard, then the sewage. 4, the water level table class must be flushed once. Flushing, according to a predetermined program, the first closing valve and open the drain valve, flushing steam valve, when attention is blocked steam origin; steam valve is then closed, when attention is blocked antecedents water. Flushing valve, until the water becomes steam, some a little longer, in order to guarantee no false water level. Hot water boiler fuel gas safety checks must be carried out to prevent the presence of explosive materials in the fuel to prevent the risk of explosion.
