After electric oil steam boiler price shutdown, how maintenance? When long-term disabled electric steam boiler, furnace should pay great attention to external corrosion and maintenance problems. First, after power shutdown cooling steam boiler, the ash must be thoroughly cleaned and the heating surface fouling the upper grate, the lower portion of the furnace. Then to maintain a certain degree of natural ventilation flue. In general, in order desiccant moisture should be placed in the furnace, flue. The quicklime as a drying agent, within the furnace or flue gas per cubic meter should be placed generally about 3kg. After placing all the ventilation should be tightly closed doors. After the change of lime powder to be replaced. Low-lying position as boiler room, ground during shutdown severe flood tide, often approach should be used and placed a small fire to dry desiccant combination. If the boiler shutdown a long time, after the complete removal of soot coated with an anti-corrosion red lead paint in oil or other metal surface furnace. As for anti-corrosion maintenance methods inside the furnace shutdown, the shutdown Yaoan the length of time to be. In general, no more than one month shutdown maintenance wet available, more than one month should be taken to maintain dry. To note the following problems when a dry maintenance: desiccant boiler not in direct contact with the metal surface, may be mounted in a container such as the iron plate after the desiccant is placed, and a hole for shutting the other hand hole cover, valve steam, the water pipe change must cut lime powder should be replaced.

Gas oil steam boiler price loading, installation considerations gas steam boiler is a very wide range of special equipment, usually built in the boiler room. However, its load, the installation process, some issues must be taken, otherwise it may cause a certain degree of economic losses. 1, the process of handling and transporting gas in a steam boiler to be noted the following: the lifting capacity of the lifting device should be matched to the weight of the boiler Lifting. Can not be used for lifting has a length marked with a lifting lug can not be used should be chosen on the boiler rope, rope length to avoid inappropriate, leading to scratching furnace. In the loading, unloading and handling process must ensure that the boiler without any damage. 2, installation of boiler maintenance reserve space, make sure there is enough space for maintenance around the boiler. 3, the base gas steam boiler, the base of the boiler and precautions to be installed on the basis of 100-150mm above the floor of the boiler on the premises, subject to prior confirmation boiler manufacturing company with technical personnel, in accordance with the basis for construction drawings. Must stay out of anchor bolts embedded hole basis. Foundation must be able to withstand the weight of the boiler and the largest holding water amount. When the mounting base, must first be positioned. After the alignment adjustment in the end the length of two diagonal lines of the same base, then the entire tightening the fixing bolt. Base mounting reference line marked for reference. 4. General Precautions Be careful not to tilt too boilers and accessories and be impact. Can not be placed outside the boiler fuel. Do not dirty oil and water boilers should generally be installed in a separate boiler room, the new gas steam boiler room should not be connected to the house. A boiler can not be connected, (B) and (C) use of flammable liquid fire risk room. If the production plant is connected to the other, separated by a firewall application. 5, fire resistance rating of the boiler room of the building and fire safety requirements should be consistent with "architectural design code for fire protection" and "design of tall buildings for fire protection" requirements. Gas-fired steam boiler room on the ground should be smooth, non-flammable, no water, load-bearing foundation should meet the requirements. Gas-fired steam boiler supply voltage should be stable, to avoid burn electrical components. The voltage instability, is recommended to install regulators. To set the boiler room ventilation equipment, to maintain the boiler temperature at 50 ° or less.[email protected]
