Low pressure 4 ton gas fired steam boiler

Henan newly installed gas boiler 1 what kind of work before starting. Henan newly installed gas boiler before starting what should be done? These include: the tightness of (1) hydrostatic test (overpressure test), test pressure member. (2) Trial and various auxiliary electric door damper check. (3) oven. Water inside wall of the furnace and gas water boiler tubes Henan removed. (4) cooking stove and pickling. Remove grease deposits in the evaporator heating surface system, rust, oxide scale and corrosion products, and other like with lye and acid. (5) furnace aerodynamic field test. (6) flushing pipe. Henan boiler with gas flushing a self-generated steam, the second steam duct heteroaryl residue. (7) check security doors. 2. Henan gas boiler before start time and temperature of water on what regulations? why? Water speed before the start of Henan gas boiler should not be excessive, winter generally less than 4h, other seasons 2 ~ 3h, especially in the beginning of the water should be slow. Cold boiler water temperature is generally not more than 100 ℃, so that the temperature difference between the feedwater entering the drum drum wall temperature is not more than 40 ℃. Henan not completely cooled gas boiler drum water temperature, mutatis mutandis, wall temperatures, generally the difference should be controlled within 40 ℃, it should slow down or speed water. The reasons are: (1) Since the thick-walled drum, slow expansion, the wall of the tube is connected to the drum wall is thin, expanded rapidly. If the inlet water temperature is too high or too fast, uneven expansion will cause the weld cracks occur, resulting in damage to the equipment. (2) when the water supply enters the drum, the drum is always in contact with the first half wall, if the water temperature and the drum wall temperature difference is too large, the influent fast speed, on the drum, the lower wall, the inner and outer wall inter will have a greater expansion difference, caused a large drum to additional stress, causing deformation of the drum, when severe cracks.

After electric low pressure 4 ton fired steam boiler 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.

Vertical low pressure 4 ton fired steam boiler What are the advantages? With the continuous development and progress of science and technology, the boiler applications also become increasingly wide range of vertical steam boiler is not only elegant appearance, small footprint, and low power consumption, strong performance advantage. So what are the advantages of low power consumption vertical steam boiler what else? Let us to understand a small taping, convenient vertical steam boiler ignition bathing water can be discharged outwardly after two minutes a suitable temperature, without pressure, safety, a normally open tube furnace to the atmosphere, does not have any valves, to ensure safe and reliable operation. And interior of the boiler can be extracted within a few minutes, making repairs or updating the boiler is also extremely fast, short, very convenient. Second, clean the inside of the boiler fouling is a killer, many products are not remove fouling or in addition to science is not complete, but the vertical steam boiler manually to complete the removal of internal boiler fouling, will not leave any dead ends. And heating water and bathing water is not mixed with, but also add a water softener water heating cycle intervention, will not make the whole boiler fouling, very clean. Third, energy saving vertical steam boiler when the water temperature of the furnace is low, reduces the heat loss. And the use of advanced environmental protection technology, can completely smoke-free dust-free, high environmental requirements for cities to achieve energy saving effect. During use, does not produce smoke, the onset of gas boilers together as a whole, the fuel on the grate in cast from the incineration stoker opening, using a high temperature steam and coal seam combined and allowed plenty of chemical attack the combustible gas after reaction, multiple backhaul several cycles, using the pipeline full heating surface, the progress of burning thermal efficiency, heat loss can be reduced to a large extent, energy saving. Vertical steam boiler since the sale of the trust of many old and new customers praise the majority of users. Simple vertical steam boiler maintenance is also very simple, and most businesses will be responsible for after-sales maintenance boiler work, professional service staff, so please do not worry, you can rest assured purchase!

School education is the foundation for development of our country, to provide environmental and healthy living environment for students is our top priority school. Winter is fast approaching, fast boiler heating and for us to solve the problem of the coexistence of environmental protection, give us tremendous help provide heating in winter. --customer feedback
