chemical boiler manufacturer dubai
Practice a chemical boiler manufacturer dubai manufacturers Henan gas boiler 1. The general provisions adapted to a predetermined fixed pressure hot water boiler water as a medium. 2. Henan factory boiler gas boiler fireman must undergo technical training, examination, fireman holding operating permits issued by local authorities, the boiler operation is not higher than the approved categories. 3. Henan boiler manufacturers fireman on duty, must strictly perform their duties, comply with labor discipline. Henan execution gas boiler safety rules, fill in the record. Second, the preparatory work before ignition before ignition 1. Henan respond boiler manufacturers boiler gas boiler, boiler accessories and instrument check to make sure drum inside the combustion chamber no debris, complete and intact thermometers, pressure gauges, water level gauge, without loosening the fixing bolts. 2. Check the feed line, the valve main hot water pipe, gas pipe and the pipe line, the flange, the instrument complete and intact, no loosening of all bolts, valve switch position in said flexible rotation. 3. Check the pump, the burner, the controller and power supply, switches, contacts, etc. is intact. 4. Check softener equipment is working properly, test the water eligibility. 5. After the above inspection, Henan to the Boiler Feed Gas boiler manufacturers. All valves to be opened by the water supply tank to the road drum, the drain valve is opened, all the drain valve closed, to open a hot water valve Henan competent boiler manufacturers gas boiler system. To observe the water level in the water level gauge Sheung Shui, when the water level rises to the minimum water level (1/3 of the tank), water is stopped. Henan boiler manufacturers when the gas boiler water filling speed to slow, the water temperature should be appropriate. Third, Henan boiler manufacturers boiler startup and operation 1. Henan boiler manufacturers cut off the mains gas boiler, a gas conduit opening the inlet valve, drain valve. 2. Check the gas concentration in the gas pipeline, the check valve on the pipe flange connections without leakage phenomenon, if any should be handled immediately. 3. After the inspection is completed, the power sent to the boiler controller, switch on the power of the burner. 4. Check that the controller parameters are normal, the system comprises a gas supply, water supply system, ignition system and flame protection, water protection system control, pressure control and protection system, electronic control box and the like. 5. Open Henan boiler manufacturers gas boiler circulation pump, observe thermometers, pressure gauges, and the corresponding water level gauge pipe fittings for water leakage. 6. Henan boiler manufacturers should be based on a gas boiler the ignition furnace, use of different methods of operation, after prolonged shutdown should be small fire. 7. After firing boiler manufacturers must closely monitor Henan gas boiler water level. Ensure the water level is maintained at normal level. 8. When the gas boiler manufacturers Henan boiler system pressure close to the operating pressure, check the connections for leakage, disassembled flange connecting bolts, need to tighten again, should operate sideways, the force should not be excessive, to prevent the bolts off. Water level in the water level in the normal operation of the boiler manufacturers 9. Henan gas boiler (1) should be in the visible range, the operation should be adjusted with changes in load level gauge must be washed once per shift. (2) Henan gas boiler blowdown boiler manufacturers, should take place at high water, low load operation should make protective measures. (3) periodic testing demineralized water, softened water boiler system to ensure that qualified.
Heating plant 2 tons of gas heating and hot water chemical boiler manufacturer dubai residential district heating plant is very different from that room high, normal cells in the heating room is generally about 3 meters high, and the factory premises heating area is generally about 6 meters, so this As a result originally applied to district heating boiler plant but does not apply to heating. In general, one ton gas hot water boiler to meet the 10,000 square meters of heating, as the heating plant, engineers need to be determined by the position of plant height and plant are located. Provide some small series several types of gas boilers for reference: WNS1.4-1.0 / 90/70-Q, WNS1.4-1.0 / 115/90-Q are provided both the boiler pressure of 1.0Mpa, design of boiler efficiency was 95%, the exhaust gas temperature is lower than 80 ℃, condensed recovery can be installed according to the needs of users. Both gas boiler characteristics: 1, 2 fully automated operation, condensate recovery unit 3 boiler thermal efficiency, easy installation, fast and do not take up space
If you stop using a condensing chemical boiler manufacturer dubai, maintenance is also required, because if the boiler is not working temporarily ignore the words, there may be other adverse effects.
Recently, the letters and the ecological environment unit, the letter of "chemical boiler manufacturer dubai 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.
