6 tons gas fully automatic 4 ton coal steam boiler steam pressure adjusting a boiler operation, must frequently monitor the pressure gauge indicated. To maintain stable steam pressure, boiler pressure must not exceed the design pressure. Second, increasing boiler load: Steam pressure decreased boiler load is increased, if the level is high at this time, the amount of water should be reduced to a water supply or suspend, the amount of coal and increase the air volume. Gradually increase the amount of water at the same time to strengthen the burning, keep the steam pressure and the water level is normal. Third, the boiler load reduction: the vapor pressure rises to reduce boiler load, if the level is high at this time, the amount of coal should be reduced and the air volume, reduced combustion. Then the appropriate water reduction or suspension of water supply to the water vapor pressure and stability in the nominal range. Then press the normal combustion and the amount of feed water 8 to adjust. If the actual water level within the boiler is low, to increase the amount of water should, until the water level returns to normal after the combustion and needs to be adjusted according to the water vapor pressure and load changes.
Washing plant choose what fuel fully automatic 4 ton coal steam boiler more cost effective? Washing plant with a steam boiler fuel is more cost effective to what has been plagued by the problem that a lot of users, and today we analyze this problem. According to cost savings for the selection of coal-fired or biomass steam boiler more cost effective, gas steam boiler is relatively easy but the cost is relatively high, in some places not to use coal and no natural gas pipeline, then select the burn methanol, more than liquefied petroleum gas and fuel oil province, Taikang County Hengyu thermal equipment Co., Ltd. is specialized in producing supervisory inspection-free steam boiler, a more comprehensive model specifications from 0.3 tons to 0.5 tons of large tonnage steam boilers, coal-fired fuel, raw materials, fuel gas and combustion of methanol, fully automatic operation out of steam quickly and does not require supervisory inspection, I have a lot of cases washing plant, the company Sina, Netease, Tencent and other major news HC have reported. What you do not understand can inquire our company.
Thirteen Five release plan indicates that China's move towards green development pace firmer, Beijing SASAC Building Materials Service Center from its start, the use of green boiler heating for low nitrogen as the primary task before the onset of winter. SAC Building Materials authorities after preliminary investigation and after the screening, the other fast boiler R & D experience in the field of boiler cleaning two decades expressed appreciation can, in August 2017 signed a five Thalia T6 series one boiler and two vacuum with fast Boiler condensing gas boiler products contract.
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.
