classification of steam boilers

An adult bathing water per hour in about 0.2 to 0.3 tons, is between 20-30 tons of 100 heads of water per hour. Therefore, only an hour to meet the boiler to provide hot water between 20-30 tons. Taking into account various factors such as bathing water temperature difference is small, we estimate that 100 bath with a shower head needs about 2 tons bath boiler. If you also need a bath dual-use heating, it is necessary to calculate the actual heating area. You can set your heating and bathing area nozzle inform our online customer service, later, the technician will make a detailed analysis of introduction.

Hot water boiler is the essential equipment of our hotel, one of the parties to provide fast condensing pressure hot water boiler immediate operational effect. Our demand for environmentally friendly and out of the hotel itself, very high environmental performance requirements for boilers, party fast products fully meet our needs, the index after testing are in line with the relevant provisions of the State; with the outside atmospheric pressure remains stable sufficiently improved security index boiler, eliminating our worries. --customer feedback

The method of prolonging the life of electric hot water boiler hearthCast iron cooling stave is the first choice for prolonging the life of electric hot water boiler hearth. In recent years, copper cooling stave has an increasing trend, but practice shows that cast iron cooling stave and copper cooling wall are adopted when the thickness of refractory material is sufficient. The temperature change of the hot surface of the refractory material is not obvious. At present, 20 years or more service life of blast furnace at home and abroad, electric hot water boiler hearth is realized by cast iron cooling stave. This shows that the cast iron cooling stave can meet the service life requirement of 20 years or more. It can be seen that the copper cooling stave has little benefit, but the cost is greatly increased. Therefore, the electric boiler recommends the furnace hearth to choose the cast iron cooling stave. 2, cooling The water pipe should be set under the bottom of the furnace: the bottom of the electric hot water boiler is not suitable for excessive cooling, and the excessive cooling is not conducive to the formation of the bottom erosion of the pot, which will aggravate the tendency of the hearth's elephant foot erosion. The practice shows that if the cooling pipe is placed on the bottom of the furnace, there will be more obvious elephant foot erosion on the bottom of the furnace, but it is better to set the cooling pipe under the bottom of the furnace. Only by adopting appropriate cooling intensity on the bottom of the furnace to promote the formation of reasonable bottom-like erosion of the boiler can the corrosion tendency of the hearth's elephant feet be alleviated and the life of the hearth can be prolonged. 3, deepen the depth of the dead iron layer: the United Kingdom, Japan, Germany and other countries, according to their blast furnace use, all proposed to add the dead iron layer Deep to more than 25%, it is beneficial to improve the life of electric hot water boiler hearth. Increasing the dead iron layer has more effect on delaying the circulation erosion of the furnace hearth of the electric hot water boiler than the penetration erosion of hot metal. Therefore, deepening the dead iron layer will increase the erosion area of the hearth, but the weakening of the circulation will delay the erosion speed in the direction of the thickness of the furnace wall. It's good for a long life. 4, thinner hearth refractory configuration: electric hot water boiler hearth refractory configuration must be aimed at forming stable slag-iron solidifying layer, blast furnace hearth longevity has been proved by practice. No matter how high-quality carbon bricks and thickness of furnace walls are used, it is impossible to match the mechanical and chemical properties of hearth slag iron. When erosion is counterbalanced, it will be quickly eroded. Only by forming a stable slag-iron solidifying layer can the hearth achieve a long life. In the design, the hot surface temperature of the carbon brick should be lowered by the effective heat transfer system of the furnace wall, so that the hot surface of the carbon brick can form a stable slag-iron solidifying layer, and the slag-iron solidifying layer should be used to resist the erosion of hot metal in the hearth and various kinds of machinery so as to realize the longevity of the hearth. In the hearth heat transfer system, the thermal resistance of the carbon brick is the largest, reaching 48%. The heat transfer capacity of the carbon brick wall is very important to the formation of the slag skin of the hearth. From this point of view, the hearth material is too thick, especially the brick lining in the iron section is thickened to 1.9 meters, and the section of the hearth is changed from circular to circular. As a square, this thickening method is harmful. The calculation of cooling heat transfer shows that the thickness of carbon brick lining should not be more than 1 meter. It is very beneficial to apply the thin hearth refractory configuration, to bake the protective carbon brick before opening, and to spray the protective layer with good performance within 1 layer of 100mm in the hearth.

Boiler maintenance electrical precautions electric boiler in addition to strictly purchase, use also requires practices, so as to avoid danger to the person. So how does it perform maintenance? Here to tell you about it a few precautions when maintenance: 1, electric boiler maintenance, must cut off the power, pressure relief. 2, the burner every two months to be removed from the electric boiler, carefully remove foreign bodies such as dust and soot. Photocell light-receiving surface wipe once a month, fuel filter should always be kept clean and filtering capabilities; carefully clean the filter in the pump, do not break the seal. Oil-burner not idle, so as not to damage the pump. 3, the water level gauge should always be kept clean, rinse the purge valve is opened, the water level in order to ensure a clear day. 4, pulling the safety valve once a day, to prevent rusting failure. These are electric boilers attention when maintenance issues related to the introduction, in addition, we want to mention is that after the work is completed, to check whether the tools, materials, complete accessories, such as to prevent left in the furnace space inside. Someone delisted before leaving the job site after acceptance, and then do the maintenance records, to prepare for subsequent queries. Hope that the text content can be helpful to you, regular maintenance can extend the life of electric boiler.

Brotan boiler: a rarely used boiler for steam locomotives that combined a conventional fire-tube boiler barrel with a water-tube firebox. There is a prominent steam drum above the boiler barrel, making it resemble a Flaman boiler. Brotan-Deffner boiler: a variant of the Brotan boiler. The steam drum was shortened and placed behind the boiler barrel, giving a much more conventional silhouette.
