Steam boiler must be shut down? For gas-fired boiler will be some companies: the higher cost of oil-fired boilers and electric heating boilers, many SMEs simply can not afford, the thermal efficiency of the boiler is too low, gas consumption often can not keep up. Many reasons why gas boiler known as the preferred place of the main gas boiler. In business consulting to some customers learned, after being forced to shut down the gas boiler, no steam, the company has only discontinued. In order to survive companies only replace the boiler, to select the gas-fired, oil-fired boiler, electric heating boiler and a biomass pellet boiler. Currently the market for natural gas boilers only major selection, analysis of the reasons is that gas-fired gas boiler is fully automatic, with no pollution. But in reality, many businesses faced to replace the boiler, gas pipeline did not pull in place, some companies simply do not have natural gas pipeline, fire steam boiler must be shut down? Gas boiler gas boiler, not to mention the natural ventilation. This is the biggest obstacle currently facing.

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!

Henan coal-fired boiler plan according to Henan authorities learned that, as of October 31 this year, to central heating in provincial cities, provincial tube county, county and other built-up areas within the area covered so the organs and institutions and railways, housing residential, hotels, baths and other coal-fired boilers are dismantled or clean the transformation of objects. 11 months ago will be completed 849 sets of 10 tons of steam coal-fired boilers and removal of the following, or the transformation of clean energy. For the clean energy transformation principle is that burning natural gas, liquefied petroleum gas, electricity, biomass briquettes, coal gas and other clean energy programs in addition to the completion of the boiler or dismantling of the unit, the province will also give some financial subsidies. Will also Chaigai boiler as markers official standard for the principle of demolition is not able to recover the use of a standard boiler. That theme boiler must be removed, the chimney must be removed, associated piping and wiring must be removed or cut off, boiler-related write-off procedures. If you can not practice the subject matter must be removed to dismantle motors, blowers and other major equipment
