gas industrial steam boiler for sale

WNS type gas industrial steam boiler for sale system control principle: ①, after WNS type gas steam boiler on the power switch, click on the pump control switch open position, after boiler feed water rises to the normal position, click-burner power switch, clicking the start button, the control system power is on, the burner into the working state, according to the operation program for the controller, to be re-ignition burner fires into the combustion state, the boiler enters normal operation this stage. ②, high output level when the water level rose to a high level alarm signal indicator light, when the water level rises to the pump stops running + 25mm, the water pump when the water level falls -25mmm automatic restart, when the water level falls -50mm, outputs a low level alarm indicator light, with bell sound, and cut off the power to the controller to achieve protection shutdown, -75 mm when the water level falls, the output signal of low water level indicator light. ③, when the pressure is raised 0.73MPa, the output signal of the first indicator light overpressure, combustion conditions and off the controller circuit, the controller stops the shutdown. Output when the pressure rises above a second overpressure 0.75MPa signal issued bell sound, alarm and cut off the power supply control system implemented emergency stop. Regulating the pressure when the pressure exceeds the upper limit, the controller output signal of a small fire fire closed valve, a valve to open the small kerosene ignition burner. When the lower limit pressure drops below the regulated pressure, the controller outputs the fire signal to open fuel valve fire, the fire to burn. ④, after the failure of the burner failure occurs, the burner control valve is automatically shut down to stop the oil combustion.

Recently, the letters and the ecological environment unit, the letter of "boiler air pollutant emission standards" in the "gas boiler exhaust pipe predetermined height of not less than 8 meters, within 200 meters from the building around the radius of the new boiler room chimney when was the tallest building in which the chimney should be higher than 3 meters "requirement questions.

First, the new urban gas boiler chimney should be performed outside the specified height is 3 meters above the surrounding buildings (there are many communities within 200 meters around the building height higher)?

Second, on the 20t / h steam boiler and above, and more than 14MW hot water boiler to be installed pollution-line monitoring equipment, this means that a single 14MW boiler or boiler means the total audience of 14MW?

Third, for example, I have more than 2MW heating station natural gas hot water boiler 7 units, exhaust gas through the two exhaust pipe emissions, the need to install pollution monitoring equipment?

A "boiler air pollutant emission standards" (GB13271-2014) states that "fuel, gas boiler stack height of not less than 8 m, particularly boiler stack height is determined by the EIA document approved. Chimney around the new boiler room when there is a building within a radius of 200 meters, the tallest building in which the chimney should be higher than 3 meters. when there is a building within 200 meters around the new boiler house chimney radius, "according to the provisions in the new urban area gas boiler should be implemented", the chimney should be higher than the provisions of the tallest buildings in more than 3 meters, "the.

Two, 20t / h steam boiler and above, 14MW and more hot water boiler must be installed in the line monitoring apparatus contaminants "14MW and more hot water boiler" means a single boiler.

Third, on the "exhaust gas through the two exhaust pipe emissions, the need to install pollution monitoring equipment" problem, according to "People's Republic of China Air Pollution Prevention Law" Article 24 "key sewage units should be installed, using air pollutant emissions automatic monitoring equipment, and environmental protection departments to monitor network devices, monitoring equipment to ensure the normal operation of public and emissions information in accordance with law. "provisions, as well as the" State Council on the issuance of three-year action plan to win the blue sky to defend the notice "(Guo Fa [2018 ] No. 22) "outfall height of over 45 meters of elevated source, as well as petrochemicals, chemicals, packaging, printing, painting and other VOCs emissions from industrial sources focus, the focus of sewage into the Directory of key areas should be basically completed by the end of 2019 to install flue gas automatic monitoring facilities, the country should be basically completed by the end of 2020 the automatic installation of flue gas monitoring facilities. "requirements, if the exhaust pipe where the company was listed as key units of sewage, flue gas monitoring facilities should be installed automatically, otherwise, no installation.

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!
