Learning materials heat boiler 1, the boiler is three safety accessories: water gauge, pressure gauge, safety valve. 2, the normal operation of the boiler water level is 0 ± 40mmH2O, the maximum does not exceed 0 ± 80mmH2O, the normal water pressure of 5.5MPa, to allow the fluctuation range of 4.5-6.0MPa, normal pressure boiler feed water temperature should be 105 degrees Celsius. 3, steam flow is not larger than the normal water boiler feedwater flow reasons, the measuring device instrument to do so. 4, the steam flow rate is less than the abnormal overheating damage reasons of water flow, water wall damage, damage to the economizer, the boiler is full of water, measuring device instrument to do so. 5, points on the furnace process CCP washed three times water gauge, pressures of 0.05-0.1MPa, 1.0MPa, 2.8MPa. 6, it is determined whether the normal water table and put into operation to see if the water level fluctuates slightly exemplar. 7, the boiler water pressure test and the test is divided into P overpressure test of two, when the water pressure P test, the boosting speed of not more than 0.35MPa 0.5MPa down rate does not exceed per minute. To the boiler water blowdown 8, the pressure in the boiler shutdown boiler water temperature drops below 80 degrees Celsius. 9, the position of each ordinary pressure test is hydrophobic doors: a door opening, the second door is closed. 10, the boiler-burner with a swirling-type and DC type two. 11, elemental analysis of coal with a composition: C, H, O, N, S, moisture, ash. 12, the main component of the blast furnace gas is: CO.'S time, nitrogen gas, blast furnace gas pressure is lower than 1500Pa, the user must reduce the amount of gas. Fire stop its pressure 1000Pa, working pressure 4000-8000Pa, the upper limit for the dangerous pressure 10000Pa, the lower limit is 2000Pa. 13, the main component of the coke oven gas: CO, nitrogen gas, coke oven gas pressure is lower than 1500Pa, must reduce the amount of gas, which pressure is 500Pa fire stop, working pressure 5000-7000Pa, the upper limit is 8000 Pa pressure the risk, the lower limit is 1500Pa . 14, the high, the main features of coke oven gas is flammable, explosive, toxic. 15, proximate analysis of coal with a volatile content, fixed carbon, ash and moisture. 16, boiler water circulation loop fault has stagnated, cycling back down the tube vaporization, soft drinks stratification. 17, the pulverized coal burning furnace radiation heat from a heat source of flame, high temperature flue gas convection heat. 18, the pulverized coal ignition and quick combustion conditions are sufficiently high temperature furnace, a sufficient amount of air mixed well, pulverized coal and air. Enough burn time. 19, ignition of pulverized coal into the combustion stage, the combustion stage, burning ember stage. 20, boiler mechanical rolling bearing does not exceed a predetermined temperature 80 degrees Celsius, the slide bearing does not exceed 40 degrees Celsius. 21, with factors affecting the steam load boiler water, boiler water salinity, pressure change, the vapor space of the drum height. 22, the principle of the steam separator drum gravity separation, inertial separation, centrifugal separation, separation of the water film. 23, the first ignition of the pulverized coal volatiles, fixed carbon is the latest ignition, the combustion of carbon is the longest. 24, steam soluble salt contaminated steam quality reasons, mechanical carryover. 25, the normal operation of the boiler drum water level in the glass tube than the water level high 50MM, when the water level in the steam table overall door leak, the water level high water table, the total gate leakage when the water level is low. 26, a method for enhancing heat transfer with a heat transfer coefficient is increased, raising the average temperature difference between the heat transfer, the heat transfer area is increased. 27, into the boiler furnace wall refractory layer, three-layer insulating layer and the sealing layer. 28, light blue flame blast furnace gas, as a bright golden yellow flame co-firing light yellow flame, coal, coke oven gas when the combustion gas as a combustion time. 29, the boiler by the "pot" and "furnace" composition, "pan" refers to a soft drink system is mainly composed of the drum, the downcomer, the header, waterwall, economizer, superheater composition; "oven" refers to a combustion system, a furnace, a burner, an air preheater composition. Calorific value 3.27GJ 30,1 tons of steam.

What are the indicators of factors affecting the efficiency of the 1t coal fired steam boiler Shandong? State basically in full swing during the move from coal to natural gas, hot water boiler with greatly minus the fine dust contamination, together with nitrogen oxides and other harmful gas emissions have been manipulated. Power is an important goal of measuring target hot water boiler, give you a look behind the cause of a direct impact on several hot water boiler power targets. By examining the relevant departments, and hot water boilers consume more important from these two local: the burning air-fuel ratio unqualified and heat loss. Possible to decrease heat loss can be recycled at the end of the formation of the latent heat of flue gas hot water boiler assembly, or with more kinds of class condensing boiler. Burning fuel ratio unqualified inappropriate Summary: General hot water boiler according ejector incinerator machine, causing air-fuel ratio can not be flexibly adjusted. 70% of the hot water boiler is a mechanical blower according burning machine, leading to substandard fuel ratio has the following several reasons: the more important fuel ratio failure probability can be divided into two types: When oxygen is overrun, there will not be excessive cold air is heat, hot water boiler power lead to the use of improved hot water boiler output target weakened; when oxygen is non-compliant, there will be insufficient burning phenomenon, showing a hot water boiler output target weakened. Shandong gas boiler steam boiler talked about how sewage? (1) inside open blowdown valve; (2) gradually open the blowdown valve external to warm up and sewage pipes; (3) an external switch repeatedly discharge water valve, slow flush pan scale , so that as the scale is discharged; (4) locking the inner blowdown valve, between these two discharge water storage water drain valve; (5) locking the outer blowdown valve, sewage terminated. When the people usually use gas steam boiler, power outage situation is obviously occurs when there is, admittedly now very small probability of occurrence of a power outage, What, then the people can not ignore this kind of situation may occur. The author taught the people, process knowledge this type of situation from occurring. First, after the power outage, the total mass to quickly lock steam boiler gas valve, this kind of boiler is to avoid the effect of leaking. Second, the next step is to lock the main switch valve with various natural gas steam boiler circuit. Third, locking gas steam boiler slag coherent various water discharge valve block, otherwise will probably cause additional problems of a coherent gas steam boiler. Fourth, to lock the various air intake valve deaerator. Fifth, the above outline done, in accordance with the order of daily occurrence to stop using the shutdown to manipulate, and verify that the volume of water in the furnace, gas and other energy corresponding to the description. Power outages may now be able to basically be able to say that very little gas steam generating boiler work, What, then public still can not completely avoid this kind of situation, which also requires manipulation of the masses of standard rules of this kind of situation occurred after carefully , as if such a situation occurs, etc. without question.

Boiler Association party leaders to come soon Group: innovation and development has won high praise, Secretary General of China Association for boiler water treatment boiler and arrogance Ling Wang, Assistant Secretary Guo Hua, chief engineer Tongyou Wu and his party three people come fast Boiler Group inspections visits, Luhai Gang president accompanied by full enthusiasm.
