The reason the gas fired boiler parts burner increased noise analysis when making use of the gas boiler and found this small fire normal, but this time turn the fire, extinguished or flashing instability. First speaking, that is because of this fire damper of the air volume setting is too large; i.e. after an oil fire because the micro-switch valve (damper outermost that group) inappropriate setting (set lower than the fire damper of the air flow larger) burner gas noise increases, mostly because the oil shut-off valve which is closed or lack of oil into the oil filter clogging; or, this is because of low temperature into the oil, the viscosity is too high or the pump into the oil temperature is too high; oil pump failure; fan motor bearing damage; there is because the fan impeller dirty equipment resulting in large noise. The above-described failure when using gas boiler, but also because the viscosity is too high oleaginous easy to be atomized (heavy oil); cyclones and because improper disc and the nozzle pitch; Note that because the fire is worn or dirty nipple; also because this preparatory tank the heating temperature is too high, causing the oil pump oil feed steam does not conform; or because the fuel inside the boiler resulting aqueous oil. When the above-described fault gas boiler used to perform this process, the test should be done gradually decreases; after heating temperature should be; adjusting the distance (between 0 ~ 10mm); clean or replace; is set to about 50 deg.] C to about; or drain oil change.
Structural characteristics and rational utilization of the power of the furnace structure characteristic electric fired boiler parts hydraulic computing There are two methods for electrical boiler furnace: a designing new electric boiler, first by combustion requirements, according to the selected grate area of the heat strength and the furnace volume heat intensity, determined baked and a preliminary discharge area is determined that the furnace volume, structure and size. Two boilers according to preliminary estimation method is recommended to determine the area of the grate and furnace volume. Now Yaoan claim preliminary heat radiation heating surface arranged in the furnace, and the furnace structure is arranged drawn sketch, thereby performing the furnace structure characteristic calculation. When checking the conventional electric boiler furnace, if its structure is known, the furnace must be characteristic calculation means. Electric boiler furnace structure characteristic calculation means provide the necessary data for the furnace heat. After the furnace when the heat transfer calculation, checking furnace exit gas temperature is unreasonable, the institutions respond to the furnace and the radiation heating surface is arranged to be modified, and then calculated. The surrounding electric boiler furnace volume: Wall roof and around the center line of the plane (if the waterwall tubes covered with a refractory coating live bricks, where the surface is not Wall for Xianghuo arranged to the furnace wall surface of the wall. outlet chimney at the top of a row of tubes centerline) and a bottom surface of the plane. Unavoidable presence of various types of hydraulic oil flowing through the hydraulic valve when the pressure drop and flow loss, energy loss in this portion of the large proportion in the total energy loss. Therefore, a reasonable selection hydraulic, a pressure adjusting valve is also an important aspect of power loss reduction. Flow valve flow rate adjustment system according to the range of the minimum select and ensure stable flow can meet the requirements, the pressure in the pressure valve satisfied hydraulic equipment work properly, try to get a lower pressure. A reasonable choice of hydraulic oil. When the oil flow in the pipeline, will exhibit a viscosity, while too high viscosity, will have a greater internal friction, resulting in heating oil, while increasing the fluid flow resistance. When the viscosity is too low, easily lead to leakage, reducing the volumetric efficiency of the system, therefore, generally choose suitable viscosity and good viscosity-temperature characteristics of the oil. Further, when the oil flow in the pipeline, there is also along the local pressure loss and the pressure loss, so the design of the pipe line as short as possible, while reducing elbow.
Thermal efficiency of coal-fired fired boiler partss and boiler standard reference card Is there a difference: in the specific types of boiler, the following will explain to, this kind of boiler coal-fired boiler, and its Web site or in the product, so it is very it is necessary to become familiar with and understand, so that, in order to have a comprehensive understanding of the product website, and also to broaden their knowledge and thus, in its study on the road forward. 1. oil-fired boilers and coal-fired boilers that heat the surface of the furnace, Is there a difference? Fuel oil and coal-fired boilers, which are two major types of boiler, the boiler is in this category, but they get hot surface of the furnace, there is a certain difference, is different, so the on this issue, that the answer is yes. In addition to an outer surface heating furnace, there are differences in other aspects. 2. coal-fired boiler, if it is less than 1 ton of steam, then, the thermal efficiency is how much is? Coal-fired boilers, if it is less than 1 ton of steam, then, the thermal efficiency of the boiler, within the range of 73% -79%, and want to obtain specific parameters, reference may be TSGG0002-2010 "energy saving technology Regulatory boiler regulations, "the standard to obtain accurate values. 3. General boiler certificate, if there is gas and coal-fired boilers of points? Coal-fired boilers, which are how many MW? General boiler certificate, there is no gas boilers and coal-fired boilers of points, so at this point, we should have a correct understanding, you can not go wrong. The MW coal-fired boilers, in general, is 0.35-7MW this range.
AMD Power were to buy 10 tons of steam and one 4 tons of steam condensing steam fired boiler parts fuel gas from the company for cell processing company production and construction. From the analysis of the demand to the boiler factory, by the company solely responsible for AMD Power fully demonstrated the company's confidence in me, the smooth progress of bilateral cooperation.Free Chat
