electric steam boiler efficiency
What kind of fuel steam boiler with a cost-effective: steam boilers for industrial production of stable and high-quality delivery of steam, wide range of applications. Depending on the fuel, coal-fired boilers can be divided, biomass boilers, gas-fired, oil-fired boiler and an electric boiler.
Wuhan Yu Dahua Group Co., Ltd. is a cotton based, weaving, knitting and textile car decoration installation in one of the cross-industry, diversified and comprehensive export-oriented enterprise groups. 2017, the Group expanded production scale textile processing, the number of new production lines, the Group's original steam boiler can not meet the growing demand of orders in urgent need of a new steam boiler purchase. When selecting vendors steam boiler, the boiler output device side fast sustainable high quality steam attracted, decided to cooperate with the fast boiler. Fast art by side to the user site needs analysis, to provide two integrally condensing gas steam boiler (WNS4-1.25-Y.Q).
Electric steam boiler is electrically heated by electrical power installed for the manner of thermal energy, so that the completion of the reaction the boiler, the steam output device outwardly, is a new innovation of "coal to electricity" policy.
Maintenance fuel gas boiler: the oil furnace shutdown furnace to be cooled to below 70 ℃ water to boiler water exhausted, the internal completely remove the dirt, washed away, all manholes, hand holes, pipe valves tightly blocked, and treated with blind plate and the steam boiler operation completely isolated. After all of the alkaline solution is added, and then injected into the soft water boiler, until the water coming out from the highest point till the boiler, the water supply valve is closed, note that the average mixing an alkaline solution inside the boiler. Shutdown more than one month should be maintained using a dry method, the following can be wet shutdown heart month regimen. To schedule the maintenance period Microflame oven, schedule the water cycle, the concentration of the alkaline solution throughout the same. Every five tests also take a basic solution, such as alkalinity less than 5-12mmol / 1 solution should be applied. Periodic inspection outage before the boiler furnace, should be prepared to work the following three aspects: (1) review boiler furnace registration technical dossier and understanding of the transformation of the electric furnace boiler usage. In order to achieve the transformation of the electric furnace boiler external inspection within the time aware of the general need to understand: the transformation of the electric furnace boiler design, manufacture, installation; boiler furnace revamping; boiler furnace use history and usage; boiler furnace water treatment situation; implementation of the boiler and other rules and regulations. (2) Check before shutdown preparation. First, with the production schedule maintenance shutdown date, and then let the transformation of the normal furnace boiler shutdown program shutdown, but slowly disheartened. Injecting cooling method may be employed downcast water, replacing the water cooled furnace and the furnace into line ventilation cooling. When the boiler water temperature was reduced to 70 ~ 80 ℃, before drainage. Open all doors hole. When the door opened, to prevent warm water, steam jet man suddenly burns. Corresponding to the passage blocked pipe on the transformation test furnace boiler steam, water supply, sewage and other pipes and other run in the transformation of the electric furnace boiler. Blocked with shutter have sufficient strength to avoid being broken drum high pressure medium. To clear the blocking position is indicated. And other operational boiler furnace flue should be communicated reliably cut off.
