In recent years, vigorously promoting the "coal to gas" national project, in northern China have started to use gas coal single drum hot water boiler to provide heating and hot water for residential, hotels, hospitals, shopping malls and some entertainment.
6 tph WNS series condensing gas-fired steam boiler project for printing and dyeing industrySteam boilers provide heat source for dyeing, drying, slashing and printing in printing and dyeing industry. Nantong New Dunhuang Dyeing Co. LTD. has always been providing excellent products and after-sales service to customers for the 16 years' constant development, main business including: yarn bleaching and sales, sales of carpet and garment fabrics and decoration cloth. As the state is promoting the substitution of small gas-fired boilers, Nantong New Dunhuan decided to introduce one set of gas-fired steam boiler with sufficient output and high efficiency. A set of high-quality boiler is essential for a dyeing and printing enterprise, which can not only enhance productivity but also reduce operating costs. After some market research, Nantong New Dunhuang chose ZOZEN as their cost-effective boiler supplier. In the process of technical communication, New Dunhuang spoke highly of ZOZEN professional degree and ordered one set of 6 tph WNS series gas-fired steam boiler (WNS6-1.25-Q). This series of boilers is ZOZEN's own R&D and has good reputation in the market with excellent product performance. It has wide fuel adaptability, applicable to a wide range of fuels including natural gas, methane, coal gas, diesel, heavy oil, light oil, etc., It adopts a large-diameter corrugated furnace to ensure the completed combustion, along with a low NOx burner, the NOx emission can be controlled below 30mg/Nm3. The boiler features automatic and safe operation, can automatically adjust and protect the combustion condition, water level, temperature and steam pressure in the course of operating. ZOZEN also installed the condenser, economizer for the tail flue, which would recycle the flue gas and decrease the exhaust temperature below to 60 degrees. The thermal efficiency is as high as 98%, which is higher than the same products in the market.
"Euromonitor" closed series of boiler condensate recovery system, the condensed water directly into the boiler temperature, with three-pass boiler air preheater + + economizer, full use of the flue gas heat recovery and then the temperature condensate from the source use, reducing energy waste and significant cost savings for businesses, the effect is immediate.
Gas boiler SZS, WNS, F, A, L, N, B and other parameters have what meaning? SZS gas boiler water is commonly used parameters. Wherein the meaning of each letter, S: double drum. There are two drum boiler, goes under the distribution structure. Z: vertical type. Using the "D" type arrangement, arranged longitudinally down drum, as the flue gas flow partition Wall full mode, the left side of the boiler convective tube bank is arranged. S: combustion chamber. Fuel is powdered (solid fuel, such as coal), mist (liquid fuels, such as oil), gaseous (gaseous fuel, such as natural gas) along with the air into the furnace (combustion) combustion in suspension. WNS is automatic gas (oil) parameters commonly used boiler. In which the meaning of each letter, W: horizontal. A boiler according to the design and installation of the outer layout, was lying state. An exhaust gas stream produced by the boiler is of horizontal flow, the flow of hot gas, in the same section on the exhaust gas temperature is low compete. N: internal combustion. After all of the fuel combustion flue gas, without burning the residue was heated with a heating surface directly mixed working fluid (water), and the flue gas, steam as the working fluid work output, the flame in the combustion furnace through the center of the drum. S: combustion chamber. Fuel is powdered (solid fuel, such as coal), mist (liquid fuels, such as oil), gaseous (gaseous fuel, such as natural gas) along with the air into the furnace (combustion) combustion in suspension. F: split. A: three return. N: N is low. L: condensation. B: Center backdraft.
