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.

6 tons adjusting a combustion gas dzl1 ton coal fired steam boiler, normal combustion boiler three basic aspects of indicators include a uniform supply of the fuel, reasonable ventilation, adjustment the combustion. 1, to maintain the high temperature of the combustion chamber temperature of the upper layer is preferably in the 1100 ~ 1300 ℃, flame orange in color. Flame reddish color indicates that the amount is not enough to the wind, the color white indicates that excessive wind. It should be appropriately adjusted. 2, fuel ash to reduce ash content in the combustibles to be below 10%. 3, reducing the temperature of the boiler flue gas exhaust gas temperature should be controlled below 200 ℃. 4, holding furnace negative excess air boiler is 1.2 to 1.4, by adjusting the balance of the blowers to maintain the furnace pressure is -20 ~ -30Pa. 5, the thermal efficiency of the boiler to improve the thermal efficiency of the boiler should be kept above 60%. II. Combustion Adjustment 1, the amount of fuel to air required for combustion and the amount of a reasonable distribution. Ventilation should first increase the amount of fuel increases, it should first reduce the amount of fuel supply reduced ventilation. 2, the thickness of the seam and seam thickness configuration grate speed is 80 ~ 120mm grate speed at high, middle and low profile configuration of several commonly used methods:. 9a rapid combustion of thin seam b c thick seam in low combustion. 3 thick seam combustion speed, the segment with the wind blowing principle: burn promoting intermediate ends. That is, after the coal into the coal starts to warm up the shutter, fire line front arch, the primary combustion zone, the middle grate to burn the rear grate zone. Normal combustion conditions are: fuel from the coal at the beginning of the fire shutter 300mm, uniform flames, the fire bed formation, at the end of combustion from the end of the grate 300 ~ 500mm. 4. maintain proper furnace temperature to avoid coking. The fire bed to maintain the homogeneous combustion, to avoid burning fire bed obliquely. 6. The residence time of the fuel on the grate in less than 30 minutes.

Comparison of coal-fired dzl1 ton coal fired steam boiler and gas steam boiler? Which is more cost-effective? There will be new users are asked coal-fired steam boiler and gas steam boiler which is more cost-effective in a number of economic operation? Believed to be ready to buy a steam boiler of every business relationship or personally, with you today, I will work together to analyze these two boilers in operating costs to do a comparison. First, the first point to analyze procurement costs: Because gas steam boiler in the annex above techniques and configurations to be clear lead and coal-fired steam boiler, gas steam boiler supporting a dedicated burner, put the cost of just one burner price opened, so that the same tonnage of steam boilers, steam boilers high gas prices than coal-fired steam boilers and more. The second point to analyze construction costs: The costs mainly from the boiler room, boiler tubes of steam investment funds. Where the coal-fired steam boiler because more appropriate auxiliary equipment, so in the boiler room construction funds to be more. There is a gas steam boiler automatic control operation, and automatic alarm and automatic protection function. Connected to the gas pipeline, the burner will automatically supply costs can effectively save staff. Coal-fired steam boiler because of the need of coal on the program, so in terms of personnel expenses wage will be larger. The third point to analyze the environmental cost: major review means that the coal-fired steam boilers now more stringent. The gas steam boiler due to the operation of the economy, environmental protection and energy saving, as well as government policy to encourage more and more widely used. The fourth point to analyze the cost of fuel: coal-fired steam boiler will be much higher than the steam boilers in gas fuels. After analyzing the above four points of view on coal in order to save operating costs more than gas steam boiler steam boiler, but coal-fired steam boiler steam boiler environmentally friendly than gas in environmental protection, environmental pollution is now increasing in recent years, so the state to environmental pollution control is relatively strict, so in accordance with the requirements of environmental protection point of view has an advantage gas steam boiler.

Hefei Limin Pharmaceutical Co., Ltd.
