horizontal type gas steam boiler for garment industry
All along, Zhangjiakou City, Hebei Province, took the central environmental protection supervision "look back" as the main problem of feedback opportunities to enhance the ecological environmental protection, pollution prevention and fight tough fight, active rectification, hard to rectify, resolute reform, promote the environmental reform task completed on schedule. We understand that in 2018, Zhangjiakou City Daly to promote projects cut coal, the accelerated clean alternative to coal consumption year on year in 2017 to reduce 1.04 million tons.
For unfinished "2017, the province's energy cut carbon coal down the main points of" cut annual coal requirements of mission objectives problem, Zhangjiakou City, supervisors coal companies cut coal, high quality coal, strengthen energy-saving technological transformation, to fully grasp the total coal consumption control and reduction of bulk coal.
The strengthening of key coal enterprises cut coal, to promote energy-saving technological transformation projects, several key coal enterprises to continuously improve energy standards. And vigorously promote the project minus coal, coal production in 2018 to defuse 8.6 million tons, out of coal-fired boilers 1663 units. Accelerate clean coal alternative, clean winter heating selected pilot cities in northern, rural complete "electricity instead of coal", "substitution of gas for coal" 6971. And vigorously develop renewable energy sources, as of 2018 the city's renewable energy installed capacity of 13,454,800 kilowatts, accounting for 74.2% of all electricity installed capacity, the highest in the country.
10 tph WNS series gas-fired fire tube boiler project for chemical industryChangchun Huatao Automotive Plastic Trim Co., Ltd. is an auto parts company mainly engaged in the production of automotive plastic inner and outer trim parts, epp foam parts and engine plastic parts. With its technical advantages, it has reached cooperation with Toyota, FAW Volkswagen and BMW. In the production process of automobile injection molded parts, many processes such as feeding, plasticizing and mold filling have a certain temperature requirement. The boiler as a heat source device plays an important role in its production line.In the face of the increasingly severe environmental protection situation, Changchun Huatao actively responded to the "coal to gas" policy and planned to introduce energy-saving and environment-friendly boilers. After a series of investigations and comparisons of many boiler manufacturers, Changchun Huatao finally purchased ZOZEN's star product of environmental protection - WNS series gas-fired horizontal type steam boiler for garment industry. This series of condensing gas-fired boilers is horizontally arranged, compact in structure and small in floor space. The combustion chamber adopts a large-diameter corrugated furnace to reduce the thermal stress and enhance the smoke disturbance, therefore, improving the heat transfer effect. with the advanced low NOx burner, the NOx emissions can be as low as 30mg/Nm3. The spiral finned tube economizer is also installed at the tail of the boiler to reduce the exhaust gas temperature to 60 degrees, and the boiler thermal efficiency can be over 98%. In addition, the boiler's fully automated control system features automatic operation and interlock protection, which meets the requirements for safety and environmental protection of Changchun Huatao production line.
How to solve the air pollution problem caused by food processing boiler operation for a long time, coal-fired boiler boiler industry occupies 90% of coverage, coal prices are not high for the economy is relatively backward areas, as well as coal-fired boilers do not ask, you can use low heat, high ash low grade coal. But with the massive emissions of coal combustion caused by sulfur dioxide, hydrogen sulfide, nitric oxide, dust and other harmful substances, causing serious air pollution, fog and haze has cropped up, China's increasingly stringent air pollution, coal-fired boiler problems faced overhaul or banned. Food processing industry as the foundation of human existence and life, in the face of more stringent food processing caused by boiler exhaust pollution treatment, clean type of fuel gas-fired boiler choice of various food companies. Take the gas boiler, it is generally used natural gas as a fuel, natural gas use since it was developed, it is known to clean energy. The main component of natural gas is methane (CH4), carbon dioxide generated during combustion only (CO2) and water (H2O), only when the combustion temperature is higher than 1300 ℃ when nitrogen oxides (NOx) and other substances, but to bring the processing operation of the boiler the air pollution problem, prefer to use natural gas as a boiler fuel. Fast boiler since its inception, and be fully independent R & D of gas boiler, condensing technology, research and development and use of FGR and premix combustion flue gas recirculation technology, greatly reduce emissions of nitrogen oxides (NOx) and other substances, NOx emissions may be less than 20mg / Nm³, our first-tier cities to meet the most stringent air pollution emission standards, compared with conventional coal-fired boilers, gas boilers party soon launch more environmentally friendly, can deliver good quality for the food processing industry steam.
Tail gas boiler heating surface, promote energy conservation, horizontal type steam boiler for garment industry, make full use of surplus gas, iron and steel ring can be part of the No. 2 boiler recently implemented gas utilization upgrading the premise of low temperature corrosion does not occur. The transformation of the original two No. 2 Power Station Boiler 220 t / h circulating fluidized bed boiler, the transformation of 200 tons / hour gas-fired boiler. To reduce the cost, Shaoguan Iron & Steel ring portion can be modified in the original boiler equipment, removal coal system, discharging systems, dust removal systems, fuel systems; Lee used equipment including the original boiler water wall, drum, steel frame, platform escalators, tail shaft convection heating surface, steam systems, water systems and some electrical, instrumentation and other facilities, while adding the blast furnace, a coke oven gas in each system, the new blast furnace, coke oven gas mixing burner 4, the combustion of blast furnace gas device 4, a low-low pressure economizer, the boiler flue gas boiler guaranteed emissions compliance and four 10 kV high-pressure fan, part of the electrical and gas drainage, tail heating surface is not provided at a low temperature corrosion occurs meter facilities. No. 2 boiler after the upgrade, to ensure the boiler flue gas emissions standards and low temperature corrosion tail heating surface does not occur under the premise, as far as possible be able to mix more burning oven gas, surplus gas consumption, save energy and reduce environmental pollution.
