Check items Notes steam boiler and a steam boiler inspection Annex 1, the steam boiler pressure gauges, they check whether the abnormal water table, bend, and the intermediate connecting pipe mounting valve opening and closing without exception. The table below shows the water level is correct, whether the water table column drain valve correctly state, pressure gauge whether there is a statutory inspection mark within the time limit. 2, steam boiler safety valve, drain valve, vent pipe to check whether they have been adjusted to a predetermined opening pressure, vent pipe installation is reasonable. Check the vent pipe is blocked, whether the anti-Chen measures. 3, the opening and closing of the drain valve discharge inspection device is flexible, the gland liner whether to allow sufficient room for adjustment. Outfall road if there is an abnormality. 4, the main valve, the water supply shut-off valve and non-return check tie their open and closed states without exception, if the valve cover material left margin. 5, the air valve in the hydrostatic test water to full state, the start point of the furnace to appear vapor must be kept open state. 6, connection pipe inspection gas and water pipes, the support, the telescopic joint, and whether the hydrophobic insulation and meet the requirements. After scaling will overheat the metal, the metal will stretch creep, modifications, bulge, serious overheating of the tube when the storm. Scale layer is a heat medium and the metal wall; between the water vapor, since the scale layer is small thermal conductivity, a significant insulating effect, greatly increasing the temperature of the metal wall fouling. It is estimated that the evaporation heating surface, furnace deposited scale often overheated collapse, deposition of scale by the pot shell (drum) regular hot drum kit, the heating surface tubes deposition of scale is often overheat storm tube larger fuel amount of waste. Daily work to do steam boiler inspection matters, in order to ensure normal production.
How were the source of gas steam boiler manufacturer of professional authority whether the authority of professional sources of gas steam boiler manufacturers supply will give everyone who has experience in planning targeted one to one plan, and we will give them a more professional supply of gas steam boiler system planning, protection able to meet top standards in line, can have a super-high-high price, they make sure to buy hardly any pressure other money, and with the characteristics and safety, it will also succeed to do formal to very good standard.
Anyang City Minshan Nonferrous Metal Co., Ltd. is a collection of urban mining, renewable resources, energy as one of the economic wisdom of cleaning companies, mainly non-ferrous metal extraction and processing work. Company to conserve energy, cleaner production for the purpose of this concept coincides with the fast boiler. Thus, when the company in the purchase of the product boiler, and fast boiler almost hit it off, by the party to provide a fast 6 tons of steam integrally condensing gas steam boiler (WNS6-1.25.Y.Q).
When the gas furnace boiler start running, be sure to pay attention to check the observation hole, flanges and valves, is loose, if you find problems in time to tighten, if the problem still find leaks, pay attention to carry out inspection shutdown.
0.05-0.1MPa pressure gas boiler at the time, to pay attention to the problem and carry out sewerage, water supply system and sewage screening test device, but also pay attention to the water level table please system; when the pressure rises to 0.1-0.5MPa time , you need to trap gauge cleaning; gas boiler when the pressure rises to 0.3MPa when the "fire load / small fire" switch to the "fire" to strengthen combustion; gas boiler when the pressure rises to 2/3 rated operating pressure, to start using heating pipes and were aspirated; and pay attention to open the main steam valve slowly to avoid water hammer phenomenon.
