9.4MW YLW coal-fired thermal oil heater for textile industryThermal oil heaters provide heat energy for the production process of dyeing, drying and printing. Noor Fatima Group is one of the major players in manufacturing and exporting woven fabrics, garments and home textile's products in Pakistan, catering to customers all over the world. The the long-time use of the company’s previous qualified brown coal dhl boilers results in performance degradation and potential risks of operation. Considering the higher running and maintenance costs, the company decided to eliminate obsolete boilers and purchase one new set of high efficient thermal oil heater. After thorough intercommunion with ZOZEN’s project leader, the company was deeply impressed by ZOZEN’s high-quality products and rich practical experience, and ultimately chose to cooperate with ZOZEN. ZOZEN offered the company the 9.4MW YLW solid fuel thermal oil heater. This kind of thermal oil heater features wide adaptability of fuels, including bituminous coal, lean coal, anthracite and many other types of coal. The heat exchange surface adopts square coil tube structure, which features more sufficient heating surface and higher thermal efficiency. Simultaneously, advanced measurement and control systems of oil temperature, smoke temperature and oil pressure ensure stable operation for a long time.
This advanced technology further improves the well-known benefits of earlier CFB technologies to include unprecedented fuel flexibility, inherently low emissions, and high availability. Designs of efficient subcritical qualified brown coal dhl boilers firing 100 per cent biomass are available to 600 MWe. This technology also offers supercritical steam boiler designs for biomass and coal co-firing applications up to 800 MWe.
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 qualified brown coal dhl 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).
Function of oil-fired qualified brown coal dhl boiler furnaceThe furnace of oil-fired boiler, also called combustion chamber, is the space for fuel combustion. The furnace in which the solid fuel is placed on the grate is called a layer-burning furnace, which is also called a fire-bed furnace, and the liquid, gas or powdered solid fuel is injected into the furnace burning in the fire chamber, which is called a chamber-burning furnace, or a fire-chamber furnace, which is also called a fire-chamber furnace, which is called a chamber-burning furnace, or a fire-bed furnace. The furnace in which the coal particles are lifted up by air to burn in a boiling state and suitable for burning inferior fuels is called a boiling furnace, also called a fluidized bed furnace, and a cylindrical furnace in which coal particles are rotated at a high speed by air flow and burned intensively is called a cyclone furnace. The cross section of the furnace is generally square or rectangular. The fuel burns in the furnace to form flame and high-temperature flue gas, Therefore, the furnace wall around the furnace is composed of high temperature resistant materials and thermal insulation materials. Water-cooled wall tubes are often installed on the inner surface of the furnace wall, which not only protects the furnace wall from burnout, but also absorbs a large amount of flame and high-temperature flue gas in the design of the furnace, which needs to take fully into account the characteristics of the fuel used. Each boiler should burn the original fuel as far as possible. The economy and reliability of boiler operation may be reduced when the fuel with different characteristics is used.
