oil gas low pressure steam boilers
Classification accuracy of gas oil low pressure steam boilers and hydraulic machines with precision introduce gas steam boiler and hydraulic classification of a gas steam boiler By Type 1, an industrial gas steam boiler: heating and for industrial production and so on. Most of the parameters for the low, low capacity boilers, the fire bed combustion and thermal efficiency is relatively low. 2, power station boilers: mainly for power generation. Most high-parameter, large-capacity boiler, firebox and allow more efficient combustion. 3, the ship's boiler: a marine power. Such boilers generally low parameters, fuel oil, the requirements of small size, light weight, easy to move more. 4, locomotive boiler: The main use of locomotive power. Lower overall parameters are small capacity boilers, fire bed combustion, requires compact, movable. Two gas steam boiler in accordance with the kind of the working fluid and an output state classification can be divided into: 1, the steam boiler: the working fluid is steam outlet. 2, hot water boiler: hot water as the working fluid outlet. 3, special working fluid boiler: export of special working fluids, such as certain organic matter. Three outlet gas steam boiler in accordance with the pressure of the working medium can be divided into: 1, pressure boiler: the outlet steam pressure 14MPA (140kgf / cm). 2, high-pressure boiler: the outlet steam pressure 10MPA (100kgf / cm). 3, sub-pressure boiler: the working fluid outlet pressure of 2.5MPa. 4, pressure in the boiler: the outlet steam pressure of 3.9MPa (39kgf / cm). 5, supercritical pressure boiler: outlet steam pressure is about 25MPa (about 250kgf / cm). 6, subcritical pressure boiler: outlet steam pressure of 17MPa (170kgf / cm?). 7, low-pressure boiler: the outlet refrigerant pressure (gauge pressure) is less than or equal to 1.3MPa (13kgf / cm). Accuracy of the hydraulic machine, determines the precision of the parts. However, only static accuracy to measure the level of accuracy of press is not very accurate. This is because the size of the mechanical strength of the press itself has a great influence on the punching accuracy. If the strength of the press itself is low, the machine will be modified such that the pressure at the instant of Ao punching pressure is reached, so that, when the above-described conditions in a static tune even good, also since the strength of the deformation caused by the sample bed, differences occur. This indicates that the accuracy of the press and has a lot of strength, and the magnitude of the intensity of the work has a great influence on the press, so that high-precision parts and punched continuous strong cold stamping, the accuracy must be selected high, and the rigidity of the press.
We know just follow the short board Western technology, and Chen Yuanshi lasting bonds, will allow fast boiler from complete "follow R & D" to "Leading Innovation" a new path of development. The completion of academician workstation, not only our party fast group of glory, boiler industry is a great event. Meanwhile, as the boiler industry is the only nationally recognized academician workstation, and we shoulder the mission is enormous, we focus on achieving "clear water and blue sky" toward the direction of the boiler "energy saving" unremitting efforts, so that the "academician workstation ' become a leading Chinese energy saving heating "benchmark."

A heated boiler is called a boiler. Heat transfer oil, also known as organic heat carrier or heat medium oil, has been used as intermediate heat transfer medium in industrial heat transfer for more than 50 years. Based on the idea of forced cycle design, a once-through boiler is developed. Generally, coal, oil and steam are used as fuel, heat conduction oil is used as the medium, hot oil circulation pump is used to force the medium into liquid phase circulation, heat energy is transmitted to the heating equipment and then returned to the heating furnace for re-heating. High operating temperature at low pressure, and high precision control for medium operation. The heat utilization rate of the system is high, and the transportation and maintenance are convenient. The closed circulation heat supply is connected with the atmosphere, can extend the service life of the boiler, liquid phase or gas phase transportation heating. The boiler adopts three-way coil design, the system sets the expansion water tank, and realizes low-pressure and high-temperature heating. The coil structure is adopted, the heating surface is sufficient, and the expansion is fully absorbed. Imported low-NOX combustion machine, combustion charge, belongs to environmental protection products. Boiler can choose advanced touch screen computer controller and digital computer controller automatic control system. With automatic temperature regulation, automatic ignition, and differential pressure, overtemperature, quenching protection. Boiler manufacturing standards, strictly in accordance with the relevant national standards. Pot The use of furnace water quality requirements: some users believe that as long as the boiler to maintain water can be, the water quality is not a choice. In fact, the quality of water on the boiler or have an impact, the editor recommends that you choose clean tap water. Because if there are impurities in the water, the use of this impurity water will have some impact on the equipment. The impurities form a thick layer of scale on the inner wall of the boiler. Scale will gradually thicken with time, and the accumulation of thickness will affect its heat transfer efficiency, resulting in a waste of energy consumption. If the scale appears, it should be cleaned up in time, so that the heat can be concentrated in the scale, which is not easy to emit. .
