WNS 1 ton diesel oil steam boiler
What types of boiler pressure wns 1 ton diesel steam boiler pressure steam boilers are common varieties of life, the pressure steam boiler also has another name called non-pressure steam boiler. High-pressure steam boiler is durable boiler is not under pressure, so there is no security risk, can be used for heating and steam supply. Working pressure of steam boilers requires energy from different fuels, different fuel types depending on and separate. 1, the electric steam boiler is an electric steam boiler to maintain normal pressure, electricity, steam boiler heating power as energy. Meanwhile, a computer equipped with a dedicated controller. Using a temperature sensor may be adjustable form a circulation system. By continuous acquisition of temperature, accurate control and regulation of temperature, to achieve the purpose of energy conservation and the automatic thermostat. 2, gas steam boiler with the implementation of the national natural gas project, gas boiler gradually been accepted. Gas steam boiler in a steam pressure of gas-powered boilers, gas steam boiler also requires computer controller. However, the difference is that electric steam boiler, gas steam boilers require the use of imported burner to heat water. 3, the fuel steam boiler can read the name of this steam boiler fuel steam boiler fuel in the fuel, including diesel, oil and kerosene. Fuel steam boiler burner needs to be, but the difference between the fuel gas steam boiler steam boiler and burner which is to be used.
Working principle and structural characteristics of wns 1 ton diesel steam boiler
Steam boiler has brought great convenience to industry. Steam boiler has driven the development of the times. The following is a brief introduction to the structural characteristics and working principle of steam boiler. Steam boiler is a machine that mainly produces steam, and many people use it, but many of them do not know much about its structure and working principle. It makes use of coal, oil, natural gas and other water-tube steam boilers with limited capacity and pressure. There is a large desire to space, and easy to arrange, steam boiler in a variety of forms. Water is heated in the drum into steam, and the heat emitted by fire in the furnace is the principle of a steam boiler. Work of steam boiler Principle:
1, the heat generated by pulverized coal combustion in the furnace is first absorbed by the water wall through radiative heat transfer, and the water boiling of the water wall is vaporized, producing a large amount of steam into the steam drum for steam separation (except for direct flow furnaces). The separated saturated steam enters the superheater and continues to absorb the flue gas heat at the top of the furnace and the horizontal flue and the tail flue through radiation and convection, and enables the superheated steam to reach the required working temperature. The steam boiler for power generation is usually equipped with a reheater, which is used to heat the steam after the high-pressure cylinder does work, and the reheat steam comes out of the reheater to go back to the middle, and the low-pressure cylinder continues to do the work to generate electricity.
2. When the pulverized coal stove is working, The position of the center of the flame will affect the amount of evaporation, generally speaking, if the center of the flame is low, the amount of evaporation will be large, and the position of the center of the flame will also affect the temperature of the superheated steam or reheated steam, as well as the high value of the flame center and the small amount of evaporation. When the flame center is low, the superheated steam, especially the reheated steam temperature, will be low and vice versa.
3, the arrangement of burners, as far as coal powder furnace is concerned, there are many kinds of combustion modes, such as front and rear wall, tangential combustion, double tangential combustion, and so on, each of which has its own characteristics. The influence on steam can not be directly determined because the same furnace can not apply the above-mentioned arrangement methods at the same time.
Xiao Bian now introduce gas wns 1 ton diesel steam boiler classification accuracy and precision hydraulic machine Henan fast boiler's steam boiler gas 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.
Fast boiler in gas boiler industry has been at the leading level for low nitrogen environmental aspects of deep research. Dingzhou Yili Dairy determined after reaching cooperation with our company, launched a work plan for the boiler low-nitrogen transformation. Yili Dairy Dingzhou three original boiler 15t / h gas wns 1 ton diesel steam boiler, NOx emissions have reached 150mg / Nm3, belonging to the boiler equipment far exceeded. After the party fast professional and technical engineers, boiler and boiler model parameters to fully understand the components, rapidly developed a specific rehabilitation programs, start from the combustion system to achieve NOx emissions of 30mg / Nm3 to meet the most stringent environmental standards of the atmosphere.
