6 tph gas fired steam boiler

Operation of the boiler, including what? Including the operation of the boiler, what does? Following on from the Henan fast boiler company to tell you about: 1. The water level regulation of normal water level in the middle of the gauge (1) of the boiler. Operation with the magnitude of the load is adjusted: to maintain a high level during low load, high load to maintain a low level. Changes should not be down more than 40 mm. (2) to be run on the water level gauge to compare the two groups, if the water level display should be corrected promptly identify the cause. (3) To achieve a balanced continuous boiler feed water, ground water supply, water supply less, to maintain the water level in the normal water level fluctuates slightly in the vicinity. (4) load change is large, prone to false level. Pay attention to judgment, in order to avoid misuse. 2. Steam pressure regulator (1) when the boiler must constantly monitor the pressure gauge indicated. To maintain stable steam pressure, boiler pressure must not exceed the design pressure. (2) increasing the 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. (3) 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 to adjust the amount of water. 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. 3. Combustion adjustment (1) combustion index. Normal combustion boiler comprises a uniform supply of the fuel, reasonable ventilation, adjusting three basic aspects combustion. B. maintain a 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. C. fuel ash to reduce ash content in the combustibles to be below 10%. d. reducing the temperature of the exhaust gas boiler exhaust gas temperature should be controlled below 200 ℃. e. excess air negative pressure holding furnace boiler 1.2-1.4, by adjusting the balance of the blowers to maintain the furnace pressure is 2-3mm. F. to improve the thermal efficiency of the boiler thermal efficiency of the boiler should be kept above 60%. (2) adjusting the combustion a. Reasonable amount and the distribution of fuel to the amount of air needed for combustion. Ventilation should first increase the amount of fuel increases, it should first reduce the amount of fuel supply reduced ventilation. b wind principle feature: 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. c is the normal combustion conditions: fuel ignition start at 300mm from the shutter of coal, even flames, the fire bed formation, at the end away from the combustion grate at the end of 300-500mm. d. Hold appropriate furnace temperature to avoid coking. E. fire bed to maintain the homogeneous combustion, to avoid burning fire bed obliquely. F. less than 30 minutes residence time of the fuel on the grate. Our company provides services related to the installation of the boiler!

Gas steam thermal cracking reaction furnace gas steam oven should be carefully introduced reflect in the use, to guard against water, acid, alkali and leakage into the low boilers using the system, the system should be installed filters installed to prevent debris into various types, to ensure the purity of the oil . Gas and steam is easily oxidized during heating, the acid value of the oil is increased at high temperatures and a large change rate. Steam oven gas kinematic viscosity gradually increases, which is due to the thermal cracking gas vapor component at high temperature, thermal polycondensation reaction. Thermal cracking reaction resulting in generation of small molecule compounds, to reduce its viscosity; oxidation temperature when the inner conduit thermally cleavage occurs at 300 ~ 400 ℃, coke formation in the pipe, the inner wall of the device, leading to heat accumulation pipe affect the heat transfer efficiency, sludge poor flowability, transfer oil accelerated aging failure, but also to the furnace, pipes local overheating, impairing the mechanical strength of the threat to personal safety.

When gas boiler outage, we should not panic, there must be the order of the operation, shut off the gas boiler. 1, the normal shutdown sequence, check the gas fired boiler fuel, gas, water shutdown valve meets the requirements; 2, off gas, coal boiler blowdown valve to prevent the surface of boiler drum cause other problems; 3, quickly closing the main steam valve prevent dehydration gas fired boiler drum; 4, close the supply valve and deaerator power switch and gas valve.

"Green Castle is the gold and silver mines," Mianyang City, Sichuan Province to respond positively to President Xi's philosophy of environmental protection, strengthen the construction of ecological civilization, and vigorously promote the city's air pollution control, focusing on small boilers county level and above cities out of coal, comprehensive enhance the transformation of 20 tons of steam / hour or more coal-fired boilers, let Mianzhou earth, the sky bluer, and more green, the water clearer.

In advance of the phase-out of coal-fired boilers, the city's focus on top-level design, in June this year issued a "county-level and above Mianyang urban area small coal-fired boilers work out program," clearly take demolition, renovation, clean energy alternatives and other measures , before the deadline to the end of March 2019, phasing out the county level and above urban area 10 steam tons / hour and the small coal-fired boilers (because of the promotion of cogeneration of small coal-fired central heating boiler replacement must be before the end of 2020 total phase-out). Not included in the program for the elimination of the objectives and tasks of various types of small coal-fired boilers, find an out of one.

Eliminate small coal-fired boilers for improving urban air quality has a positive effect. In Mianyang, a wine business one step ahead, we tasted the sweetness: switch to phase out coal-fired boiler gas boiler. Before coal-fired boilers, the company must invest a lot of money each year to buy coal used in the treatment of fly ash and slag above, and coal combustion will bring countless pollutants.

After starting gas fired boiler to boiler project, which began to corporate purchase and install a gas boiler, energy-saving cooking pot bottom, ice bucket, multi-cooler tube array, sewage tank 58 and other equipment (sets); and in 2017 December formally put into use. After coal to gas, coal storage area is no longer required, cinder storage area ,, new construction land for the enterprise, greatly reduce production operating costs. "

This year the city built-up area of ​​the city's coal-fired boiler phase-out targets small task is 25 units. City Commission by letter, the Environmental Protection Agency, Bureau of Quality Supervision and other relevant departments to strengthen organizational leadership, establish long-term working mechanism, compaction work responsibilities, in close collaboration to promote the division of labor, and strengthen supervision to ask efficiency, strict examination and approval for the record, put an end to new coal-fired small boiler, strengthen propaganda and guidance, do a solid job of work to promote the service. As of the end of November, this year's phase-out plan included 22 small businesses of 25 coal-fired boilers have completed 24 units, of which the use of special equipment to complete the cancellation of the registration certificate of 17.

City Commission by letter the person in charge, the next step, they will actively cooperate with relevant departments to intensify its efforts to strengthen the county has not yet out of the task of supervision and corporate efforts to accelerate the phase-out of the boiler has been using special equipment write-off registration certificate , guidance throughout the solid performance of the late acceptance procedures, and make due contributions to effectively improve the quality of atmospheric environment in Mianyang.
