Learn the difference between pay professionals work and waste boiler and boiler feed water for boilers of knowledge and understanding, we will continue this work, because the only way to keep abreast of professional knowledge about the boiler, and the knowledge and flexibility to apply their knowledge applied to practice, then, to ensure that the boiler had good results, avoid misuse. 1. What is the boiler professionals work? Boiler professionals work, the specific name for the boiler professional engineers and professionals work into operation and maintenance professionals work. Run professionals work: the development of operational procedures, technical monitoring in the boiler, if the boiler fails problems during operation, timely analysis and guidance to operating personnel discharge failure, ensure that the boiler safe operation. Also, record the operating parameters of the boiler, to provide accurate data for the boiler overhaul. Maintenance professionals work: development of maintenance procedures and maintenance scheduling and parts planning, at the same time, but also to develop maintenance programs, guidance personnel for maintenance work as maintenance procedures. Boiler feed water and boiler feed water 2. Is there a difference? Boiler feed water, which is from the plant to the Water and then through oxygen between the boiler feed pump into the boiler economizer soft water, boiler feed water is from the chemical water softener after the plant by chemical treatment. Although they are soft water, boiler feed water, but more complicated, but also the need for oxygen and heated before entering the boiler. So, boiler feed water and boiler feed water is different. 3. central boiler furnace temperature to be controlled in a range? The boiler is the first inspection within or outside the check? Central boiler furnace temperature is generally controlled within the required range of 900 ℃ -1100 ℃. Is the first in the boiler inspection, conducted after the external examination within the inspection is completed, if the problem has been found in the inspection process, and after dealing with external inspection out of the issue. In addition, we also need to know that, in the boiler inspection is conducted every two years, external examination is conducted once a year. 4. What is the waste boiler? Familiar with and understand the waste before the boiler, first look at waste boiler. Waste boiler, which means that the exhaust gas, waste and waste water. Exhaust: no fuel to burn in the combustion waste air emissions, mainly including soot, sulfur dioxide, nitrogen oxides and other waste gases. Waste: solid waste produced after combustion of the fuel, including cinder, oil residue and other such waste. Waste water: Some water is not used in the boiler emissions, comprising a compound, mixture, suspension, and salt, alkali larger boiler water, in addition, also water, sludge and the like fluffy precipitate. Waste boiler, which is the use of some of these techniques and recycling waste utilization, and reduce noise to produce secondary economic benefits.
Depending on the operating characteristics of electric steam boilers, mainly to properly regulate the drum and induced draft fan. The chamber negative pressure is guaranteed ± (5-10) premise mm water column (water column ≈9.8Pa 1mm) to minimize the amount of the wind, to extend the residence time of the flue gas temperature in the furnace, reduce exhaust gas temperature.
There are reasons for chemical plant boiler water wall high temperature corrosion which causes of high temperature corrosion chemical plant boiler water wall What are the causes of high temperature corrosion chemical plant boiler water wall which 1, raw coal sulfur compounds according to relevant statistics analysis shows that coal inorganic sulfide occurrence sulfur-based, accounting for 60% to 70% of the total sulfur content, the remaining 30% to 40% is organic sulfur. Occurrence majority of the inorganic sulfur in the form of pyrite, sulfate, only a small fraction of inorganic sulfur content of the sulfur in coal measurement results shown in Table 2. The morphology of pyrite by more slagging and corrosion of boiler serious implications, and therefore subject to people's attention in the course of practice, but often ignore the corrosive effect of sulfate on the Wall. Thus, in practice it is necessary to form during combustion of sulfur in coal is measured. 2, the chemical analysis of coal coal boiler is 50% to 50% of anthracite and bituminous coal, coal testing seen from the data of research institutions, the volatile coal employed in the chemical, crystalline water, CO2 and other non-combustible or higher levels of flame-retardant component, low CH4, H2 and other combustibles content, higher temperature requirements volatile release, slow release, long time to burn coal, high ash content of the combustion, appears likely to cause the waterwall reducing component. 3, the size of the inscribed circle boiler chemical analysis boiler designed to be used with pre-mixed coal, to achieve the purpose of enhancing combustion, therefore the design Tangentially Fired large, will cause a large inscribed circle after the formation of the combustion of coal pulverized coal, gas and other substances appear high temperature corrosion. Related experimental results also shows that, when the circle diameter of the boiler in the range of 8 ~ 8.3m, after leaving a nozzle air flow deflection under the action of mixing the secondary air mixed gas stream is significantly down and floating inscribed circle than the other Big. 4, when the airflow and dual channel burner boiler design analysis consider using bituminous coal and anthracite mixed, the use of a secondary higher wind speed, a wind speed is low, the size of each of 43.5m / s, 22.5m / s, a , the second big difference wind speed caused the jet rigid significantly different. Due to the impact of differences in conditions and the gas stream upstream sides of adjacent angles of qi, when a secondary stream ejected from the burner, the air flow occurs toward the back direction of the flame to the water wall offset time smaller jet velocity Merry occurs a more obvious than the secondary airflow offset such that once the separation between the secondary air flow significantly. By using correlation analysis tests like long streamers understood, a significant portion of the air flow downstream of the boiler walls against movement, so this part of the secondary air flow departing from the airflow direction, coal and other combustible materials in the combustion under insufficient oxygen supply, a certain amount reducing gas component. Because the use of the two-channel burner design, a secondary air flow separation phenomenon of increasing offset, to some extent, when a relatively strong reflux in the boiler, the flue gas, the better the effect of reflux, the more obvious the effect of fuel combustion, but it can also lead to increased attenuation of a romantic reflux stronger. Dual-channel design such that the outlet area of the burner than traditional single channel many large exit area, but also makes the primary air flow greatly reduced exit velocity. The foregoing analysis, and a dual channel design, the secondary air flow speed difference, so that a significantly reduced stiffness airflow, airflow offset serious, prone to high temperature corrosion in the waterwall. Analysis of coal pulverizing system thickness 2.5 coal boiler is based on coal and coal burning coal designed, when using low-quality coal, pulverizing system load increases, reducing the separation effect, resulting in coal particle size increases, the thickness of the pulverized coal has a significant effect on high temperature corrosion of the boiler, coal particles increase when the torch burning in a boiler long prone to decrease the effect of the combustion of pulverized coal, coarse coal particles are not completely combusted powder boiler water wall in the vicinity of the bond, so that high-temperature corrosion intensified.
