vertical 1000kg city gas boilers
The Fangkuai Group's unique full-operating vertical 1000kg city boilers operation laboratory has an annual operating cost of more than 5 million yuan, which can simulate the operating conditions of various types of boilers under multi-operating environment conditions. The laboratory provides technical tests such as test and inspection, analysis and evaluation, data evaluation, energy saving and environmental protection, and special software from materials to complete equipment, hardware to software, and even complex large systems.
How to prevent corrosion of the gas vertical 1000kg city boilers gas boiler it if the temperature is too high, some of the components of the boiler working long hours in the intense heat of the environment at work, the situation will cause boiler corrosion occurs. So, we are in the process of work what to do to reduce the corrosion of it? Here to tell you about some of the methods of preventing corrosion of boiler gas. Reason and approach demands on internal corrosion of the gas boiler must be in accordance with the methods and principles of conduct, you can now use a more extensive domestic and international gas boiler corrosion detection approach is magnetic flux leakage and ultrasonic detection. Ultrasonic Ultrasonic detection is used to measure the wall thickness after etching using the principle of ultrasonic pulse reflection. The basic principle of magnetic flux leakage method leakage flux detection method is based on the high-permeability properties of the ferromagnetic materials, magnetic permeability of the gas boiler corrosion disadvantage is much less than the permeability of the furnace, the applied gas boiler is magnetized in a magnetic field effect, when the furnace is no disadvantage, most of the magnetic lines of force through the pipe. Uniform distribution of lines of magnetic force at the moment; when the internal elbow has the disadvantage that the onset of meander lines of magnetic force, and a part of magnetic lines of force from leaking out of the outer steel pipe. Detecting the escaping magnetic flux leakage outer elbow, it can be determined whether the shortcomings exist. When the probe detects a straight guide hot oil furnace inner wall emit ultrasound pulse, to receive from the probe first reflected pulse within the outer wall, and will receive the ultrasound probe, this pulse and the pulse reflected from the outer wall of the outer appearance of the reflected pulse trip distance between the reflecting wall thickness. Gas-fired boiler in accordance with the practices and conditions set forth in the demand for the detection of practice, in accordance with the detection of ultrasonic inspection method can be distinguished way. High temperature components such as a gas boiler front panel, convection superheater and reheater temperature is the primary structural member and the like inside the boiler, a very long time to work in the harsh environment of use of the medium flame, smoke, ash, etc., and therefore the working process changes occurred in the organization and function of a range of materials, these changes hit the gas boiler creep, fatigue, corrosion, erosion and other messy aging and failure mechanisms. These high temperatures Microstructure component material will follow the extension of working time deteriorated creep damage occurs, such as loose pearlite, spheroidized carbides, grain boundary and growth mobilization, holes creep, intergranular cracking occurs .
What kind of pressure gas vertical 1000kg city boilers quality no good people bought gas pressure boiler, even gas boiler no contact with people, has been more emphasis on the market in gas boiler election time, in the selection of the boiler, the name suggests is designed pressurized gas boiler category, this means, electric boilers, gas boilers and good use of comparative advantage is up relatively well. First of all, pay attention to safety regulations, gas boiler should pay attention to the use of safe fuel, electricity; In contrast, the general election need to reduce the number of gas-fired boilers for gas requirements of sensitive issues, a lot of energy, design issues become more complex, selected gas boiler, pay attention to certain parameters is a relatively routine procedure. In view of the use of the burner, the air supply system is the best embodiment of the gas boiler, the air supply system, must pay attention to air flow, air and other details, particularly in the light housing, the motor and the associated wheel, excellent results Therefore, when using gas-fired boiler, the overall effect of highlighting the advantages of maturity is a very sensitive topic. In the detection system perspective, the use of pressurized gas boiler is based on the practical effect of the above, to ensure the safety of the gas, pay attention to the ability to run the election is now the basis of the performance of gas-fired boiler, fuel system, and even the electronic control system , becoming the selected gas boiler, note controller uses a set of programs, large LCD screen, security control is inevitable.
Combustion conditions provides rapid and substantially complete combustion of 1, a relatively high furnace temperature: the chemical reaction is the basic condition of combustion, fuel ignition and stable combustion, burn have a significant impact, maintaining a suitably high temperature furnace to important. Of course, when the furnace temperature is too high, consider the problem of slagging vertical 1000kg city boilerss. 2, the air supply amount: the amount of air supply, is to provide enough oxygen for the fuel, which is the original conditions of the combustion reaction. Air supply, fuel not get enough oxygen, it can not achieve complete combustion. But excessive air, the furnace temperature will lead to loss and exhaust loss increases. 3, good mixing conditions: Mixing is an important physical conditions of the combustion reaction. Mixing the hot flue gas in the furnace is heated to reflux of the pulverized coal flow, so as to rapidly fire. Mixing in the furnace is strongly perturbed stream to provide oxygen to the soot combustion stage surface, outward diffusion of carbon dioxide, and to promote post-combustion of the fuel burn, it is an indispensable condition. 4, enough burn time: the fuel in the furnace for a time sufficient to achieve a high degree of fuel burn, which requires a large enough volume of the furnace. Proportional to the volume of the furnace and boiler capacity. Of course, the furnace volume is also characteristics of the fuel combustion, easy to burn fuel, furnace volume can be relatively small. For example, the same capacity of the boiler, furnace volume of fuel than pulverized coal furnace is small, and vanished without burning furnace volume than coal burning bituminous coal furnace volume slightly larger.
