ASME Water Tube and Fire Tube Steam Boilers

Water tube and fire tube boilers are essentially the opposite in design. In a water tube boiler, water travels through tubes which are surrounded by the by-products of combustion, or flue gas. In a fire tube boiler, the flue gas travels through the tubes, which are surrounded by hot water. Water tube and fire tube steam boilers in ZG boiler have identified ASME certification. ASME water tube steam boilers mainly have SZS series oil & gas fired steam boiler and SZL series chain grate steam boiler. ASME fire tube steam boilers mainly have WNS series oil & gas fired steam boiler, DZL series chain grate steam boiler.

Exhaust gas has been plagued by sewage paper industry, paper industry pollution problems of the country very seriously. Fujian Heng paper packaging company has been committed to the use of clean-type boiler paper processing. October 22, 2016, David Carse, the paper with my company, signed a 6 tons of steam an integral condensing steam boiler for the production of corrugated cardboard and other paper products. I provided the boiler greatly solve the problem of sewage wastewater Heng paper. After the boiler operation, both to meet local environmental requirements, but also reduce operating costs for the constant boiler paper products.

When we use the boiler, it is unavoidable to have faults or abnormal phenomena, but in order not to affect the normal use, when the boiler appears problems should be dealt with in a timely manner, then in the face of all kinds of circumstances, how should we deal with it? Share with you some ways to handle exceptions. If only the boiler circulating pump abnormal, such as its current reduced, outlet pump pressure return to zero, which means that the pump is idling non-oil, may be caused by vaporization of oil. Therefore, first of all, Yang should take measures to identify the cause of vaporization; if the filter blockage causes the circulating pump to empty, the by-pass cleaning filter should be opened immediately; such as the new heat transfer fluid containing water or Water-decomposing gas is not excluded in the system, then the open valve should be opened immediately. If the circulating pump pressure is constant, the current increases and the flow rate decreases, the heat transfer fluid is metamorphic and the viscosity is increased, so it should be replaced or regenerated in time. If the gas containing water or decomposing is not excluded from the system due to the new heat conduction fluid, the gas should be discharged immediately by opening the valve. When the current of the circulating pump is lower than the normal value, it shows that the efficiency of the circulating pump is lower and the flow rate is decreased, which may be the fouling blockage of the heating pipeline, and the stainless steel chain should be cleaned. If the pressure difference between the front and back of the filter in the boiler increases and the pressure of the pump inlet drops, the filter may be blocked. The bypass should be opened and the filter should be turned on. Remove cleaning. In addition, the low outlet temperature of the liquid-phase heat carrier furnace and the lack of heat supply are mainly due to the problem of ash accumulation, so soot-blowing should be carried out in time. A more common problem with the boiler's grate is that it is stuck because it is broken or loose after the pin has fallen off; metal inclusions in the coal trap the grate; the grate is arched; and the tip of the slag stopper sinks to jam the grate. In view of this phenomenon, it is necessary to clean up the debris with the plate hand-down converter row, replace the broken furnace platoon and start again, if it is stuck again after the start-up, then check the causes after stopping the rotation and solve the problem in detail. At the same time, it is necessary to adjust the screws on both sides and tighten the grate, if it is still not correct. Often, you need to change the sprocket.

Oil boilers are highly efficient appliances that can heat up large amounts of water. Some models are also very environmentally friendly; because you have the option of using recycled oil or bio-diesel as the fuel source. Oil boilers provide very even heating. Though oil burners require a separate room, you have the option of installing some models outdoors. You can also have the maintenance and checks done outdoors. In case of power outages, you can still get your supply of hot water. Oil boilers are widely used in areas that have unreliable electric connections or that do not have natural gas connections.
