natural gas low pressure industrial steam boiler
Gas-fired low pressure industrial steam boiler equipment maintenance equipment maintenance points 1: 1, or twice a day to clean up slag. 2, washed once or twice a heater dust (ash door with the appliance design) weekly. 3, once or twice a month, or butter oil feeding helical gears and bearings induced draft fan. 4, a monthly injection of butter or oil to the fan motor bearings once or twice. 5, a boiler must be 2-4 times the annual emissions (emissions must promptly after filling water). 6, poor water quality, in use. 2. Before, must soften water. Gas hot water boiler with environmental protection, energy conservation, safety, salient features fully automatic operation, and ease of use. In addition, due to the operation of the economy, government policies to encourage, gas hot water boiler more and more people of all ages. Daily inspection equipment: 1, the fan regularly checks whether there is a feed screw loosening device, whether there is abnormal noise. 2, regular inspection trip tank float valve is normal replenishment, water pressure is normal. Biomass boiler categories: biomass boilers Horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass steam boiler, biomass hot water boiler, biomass oil furnace. 3, if equipped with a pump, replace circulation pump on a regular basis, and check whether the pump is working properly. Function gas boiler the ignition system that ignites the mixture of air and fuel, its main components are: the ignition transformer, the ignition electrode, a high voltage electrical cable fire. A more secure electronic ignition system called ignition pulse, is widely used Zhuoyi energy saving gas boiler manufacturers. Which facilitate saving, can simply press a finger, and safe, does not occur due to unexpected accidents occur flame, once the stall state occurs, the control system can close the solenoid valve, off the gas passage. 4, regular inspection equipment grounding cable is connected correctly. 5, to ensure the normal supply of fuel in the hopper, so as to avoid non-fuel flameout downtime. 6, it should be observed regularly combustion of the fuel in the combustion chamber. Incomplete combustion of fuel, smoke or large block to form sulfur, the sulfur should be promptly removed block and the governor to adjust the feed flow rate ratio of the fan, to achieve the desired combustion.
When the pressure of the low pressure industrial steam boiler protection small small steam boiler pressure exceeds the rated boiler steam pressure protection, the need for chain protection: is shutdown, the system stops the combustion; fire mouth can also be varied, single-stage or two-stage combustion, You can adjust the amount of oil, so the buck, to ensure the safe operation of the boiler. Fuel (gas) pressure protection and steam boiler water, as the use of multiple protection: the pressure controller typically use two pressure controller, the pressure signal converted to an electrical signal, the electromechanical converter, the function of the high pressure, or low levels of signal The electrical switching loss, external circuits or automatic control chain protection. Common pressure controller and pressure gauge, vapor pressure overpressure alarm can cut off the burner limit is reached; pressure controller adjusts single fire or dual fire burning the actual operating pressure; for large burner, the pressure may be adjusted according to the size of the size of the amount of fuel, and always maintain a stable pressure relief valve operation is the last line of defense to protect the boiler, the boiler pressure exceeds the limit, according to the set pressure relief valve design feature, the exhaust pressure relief, to ensure the normal operation of the boiler. Temperature protection temperature protection is an important procedure in the safe operation of the boiler, is particularly important for the regulation and protection of the boiler temperature steam; at the same time to regulate protective role in over-temperature hot water boilers. Conventional boiler temperature protection means is a bimetallic temperature controller.
The origin of the gas on the principle of using gas low pressure industrial steam boiler steam heating boiler called gas steam boiler. HTF, also known as organic heat carrier medium or hot oil, use as an intermediate heat transfer medium in the industrial heat exchange process has been more than 50 years of history. Based forced circulation design and development of once-through boiler. Typically coal, oil, gas fuel to oil as the medium, using a thermal oil circulation pump to force the liquid circulating medium, the heat energy to a heat transport device and then return again heated furnace, having obtained at low pressure high operating temperature, and can perform high-precision control of the working medium run. High system thermal efficiency, easy operation and maintenance, the closed-cycle heat to the atmosphere, the service life, the liquid or vapor phase delivery extended heating boiler. Gas steam boiler return three-coil design, the system is set up expansion of the water tank, provides low temperature heating. Using the coil structure, sufficient heating surface, expands sufficiently absorbed. Imports of low NOX burner, combustion, are environmentally friendly products. Boilers can use advanced touch-screen computer controller and digital computer controller automatic control. Having a thermostat, automatic ignition, and differential pressure, over-temperature, flame protection. Boiler manufacturing practices, in strict accordance with the relevant national standards. The use of gas steam boiler water quality requirements: Some users believe that as long as gas steam boiler water is held on it, the water quality indiscriminately. In fact, the use of water or gas steam boiler influential, small advice you to choose clean tap water. Because if there are impurities in the water, then the use of this device with impurities of water will have some impact. Impurities junction thick layer of scale on the inner wall of the gas steam boiler. The scale will gradually thickened over time, which will affect the efficiency of heat conduction when a thickness of accumulation is wasted energy. If the scale appears to be cleared, so the heat is concentrated in the scale easy to distribute.
In response to the state-assigned air quality improvement objectives and environmental supervision central feedback coal-fired boilers environmental pollution rectification program, Kang County, Gansu Province based on "government-led, relying on real responsibility, Take Measures to proceed with" principle, accelerate the burning of remediation work out of the coal boiler, and to develop the following measures, at present, reconstruction activities are being actively promoted.
A: a comprehensive investigation, the establishment of accounting. For urban areas, towns, Kudo industrial parks all coal-fired boilers to conduct a comprehensive diagnostic investigation, a total of investigation and the use of the boiler 31 enterprises, a total of 38 boilers, electric boilers and removal of fuel two boilers, coal-fired boilers county a total of 36, including two sets of 20 tons of steam boilers, coal-fired boiler pressure 4. In the diagnostic process, the situation boiler location, type, number of units, the tonnage, use, carefully verify the age and so on, and sort out the summary, so that a boiler does not leak, the device information is not a shortage.
Two: to strengthen publicity, and create atmosphere. Through new media, focus on advocacy, government circulars issued, will be held to promote the government leaders in charge of on-site investigation led mobilization and other forms of media offensive formation, multi-level multi-angle carry out various forms of publicity and education remediation phase out coal-fired boilers, each guide society personnel support and participate actively promote the use of coal-fired boiler units understand the situation, to speed up the phase-out of coal-fired boiler renovation.
Three: supervision of interviews, results-oriented. Person in charge of the county Bureau of Quality Supervision led, in-depth coal-fired boiler unit, for the slowness, lack of knowledge, waiting to see the business units and enlighten them with reason, and emotionally moving. With the responsible persons of the two job interviews lag to not be one of them out of the situation Reconstruction of boiler in accordance with national policy requirements, on-site recovery boiler registration certificate and ordered deadline to be removed or modified.
Kang mentioned standard by the transformation, step out, closed down closed down, to gas and electricity from coal to supervise a number of measures to actively promote the elimination of remediation coal-fired boilers. Currently the county out of 29 coal-fired boiler units, of which 15 units destructive demolition, stop burning close 12 stations, two mentioned standard transformation. The remaining seven out of focus on remediation plan included in this year, the county continues to promote this work, and to call on the unit enthusiastic, standards do not fall, the team leave, determined to complete the end of October this year, the county and below 10 tons of steam coal-fired boiler work all clear.
