On the 16th, the Hebei Provincial Ministry of Industry and Information Technology, the Provincial Development and Reform Commission, the Provincial Environmental Protection Department, and the Provincial Quality Supervision Bureau jointly convened the province's coal-fired industrial boiler transformation work conference. Hebei Province's action plan for the advancement of coal-fired industrial boilers was officially launched. In line with the idea of ​​“dismantling and banning batches, replacement and adjustment of batches, replacement and replacement of batches, and improvement of quality and efficiencyâ€, Hebei Province encourages local governments to use advanced and applicable technologies to speed up the transformation of urban and rural coal-fired industrial boilers and strive to use them for three years. , To complete 18,517 Taiwan, 59,300 tons of coal-fired industrial boilers to transform the task, substantially reducing pollutant emissions.
In principle, urban built-up areas must not be newly built. Coal-fired industrial boilers Coal-fired industrial boilers are major sources of pollutants emission in large energy consumption and industrial sectors in Hebei Province.
In accordance with the “Implementation Plan for Coal-fired Boiler Control in Hebei Province†and the “Hebei Province Action Plan for the Advancement of Coal-fired Industrial Boilersâ€, coal-fired industrial boilers with 35 tons/hour or less have become the focus of this transformation action plan. The task of rebuilding coal-fired industrial boilers in the province from 2015 to 2018 has also been decomposed into counties (cities) directly subordinate to districts and cities. According to statistics, at present, there are 18,715 coal-fired industrial boilers with a capacity of 59,300 tons per ton, and the number and capacity of coal-fired industrial boilers account for 65.3% and 59% of all coal-fired boilers.
Zou Ping, Director of the Provincial Ministry of Industry and Information Technology, said that taking into account that the coal-based energy consumption pattern in Hebei Province is difficult to change in the short term, the supply of natural gas, biomass, methanol, and other fuels should be limited to increasing coal supply. Use efficiency and accelerate the treatment of coal-fired pollutants as the main measures. In response, Hebei Province will focus on accelerating the promotion of high-efficiency pulverized coal boilers, and comprehensively promote the application of circulating fluidized bed boilers, gas industrial boilers, biomass boilers, and methanol boilers, and actively promote the efficient desulfurization, denitrification, and dust removal devices for flue gas. And transformation, to achieve the standard emissions of coal-fired industrial boilers. In the future, urban built-up areas will not be allowed to build new coal-fired industrial boilers in principle. Newly rebuilt coal-fired industrial boilers will be replaced by high-efficiency pulverized coal boilers.
Hebei to promote coal-fired industrial boiler transformation action plan
Before the seven major boiler technologies and energy-saving, desulfurization, denitrification, and dust-removal technologies were selected for selection, the Provincial Ministry of Industry and Information Technology had extensively solicited opinions from national and provincial authorities and experts in the industry to implement the representative domestic coal-fired industrial boiler retrofitting enterprises. Through investigation and understanding, the "Resources for Coal-fired Boiler Reform" was collected, and seven major boiler technologies and technologies for energy-saving, desulfurization, denitrification, and dust removal were collected and distributed to the person-in-charge of each department at all levels.
The meeting requested that all localities should formulate differentiated transformation plans based on the specific conditions of local heating, natural gas, and new energy in the location of the relevant enterprise, adjusting measures to local conditions, adopting policies, and integrating the actual technological path for the selection of quasi-fired industrial boilers. In key air pollution prevention and control areas, it is necessary to actively strive for the state to increase natural gas distribution targets and give priority to the promotion of natural gas, methanol, and other clean energy transformation coal-fired industrial boilers. In industrial parks where heat demand is concentrated, encourage the construction of cogeneration projects and high-efficiency pulverized coal boilers, and gradually phase out decentralized coal-fired industrial boilers. In coastal areas, the use of LNG, CNG, etc. is encouraged to transform coal-fired industrial boilers. In the industrial agglomeration areas such as chemical industry, papermaking, printing and dyeing, tanning, and pharmaceuticals, accelerating the central heating in industrial parks and realizing the “one district and one heat sourceâ€. In the rural areas where the grain and cotton production areas are located, the use of waste straws, fruit tree branches, etc., is encouraged to promote the conversion of small-scale coal-fired industrial boilers to biomass fuels. In regions with abundant solar energy resources, the use of solar thermal technology is encouraged to transform coal-fired industrial boilers.
In addition, the steel, building materials, coal, and chemical industries in Hebei Province are relatively large in scale, and will strengthen the recovery of waste heat, residual pressure, and combustible gas in these areas, such as the recovery of waste heat from furnaces such as metallurgical heating furnaces, building rotary kiln, and glass kilns. The recovery and utilization of coke oven gas, blast furnace gas and converter gas in iron and steel enterprises, coke oven gas recovery and utilization in coking enterprises, coal bed methane recovery and utilization in coal mines, etc., further improve the comprehensive utilization efficiency of energy.
Precision Casting Of Train Parts
Train parts casting is one branch of carbon steel precision casting, which is widely used in train markets. Precision casting of train parts adopts lost wax casting, also called investment casting. In wax pattern process,we mix stearic acid and paraffin wax.
In wax pattern making, as you know, it is better than polyethylene, and the wax deformation is small. In dipping slurry process,most of the suppliers adopt water glass technics in domestic area,but we adopt compound technics or silica sol technics. As you know, carbon steel castings will be much smoother with compound technics (compound of water glass and silica sol technics),this method is so popular with our customers, and the quality is higher than water glass technics, the cost is lower than silica sol technics.
In shell making,we adopt automatic sand-covering production line, which was invented under the guidance of our general manager.The indoor temperature was controlled by air-conditions,keeping the temperature at 24℃±1℃, which can make the castings much more stable,the internal tissues much more well-proportioned.
Our train parts as precision casting products have quality assurance in accordance with ISO9001: 2008, strict material inspection and exact dimension control, with 100% quality control. OEM order is welcome. The parts can be made completely based on your specifications such as drawing, design, sample etc.
