Coal-fired waster heat recovery boiler for paper mill to carry out a comprehensive investigation and remediation work, Luohe City, Henan Province, Li Jizhen provincial, city and town each environmental supervision departments centralized call the relevant personnel, three-pronged approach to work.
First, a comprehensive investigation to find out the base.
Li Jizhen town for all industrial enterprises, restaurants, vermicelli processing plants, farms and other coal-fired boiler with a boiler units diagnostic investigation, the establishment of coal-fired boilers ledger, so base-clear, the situation is clear.
Second, clear standards, conducting pressure.
Town leaders organized the renovation work conference of coal-fired boilers, the boiler so that the user's overall reform and the dismantling of scheduling, the town must be eliminated in the formation of boiler upgrade, you do not need to be removed out of shutting down consensus.
Third, actively coordinate, and assign responsibilities.
Natural gas is being implemented in conjunction with the "double substitution", and actively coordinate the gas boiler equipment suppliers in collaboration with the local gas company, entered into a collaboration, timely completion of "substitution of gas for coal" upgrade tasks.
As of now, the town has shut down six coal-fired boilers, the implementation of "substitution of gas for coal" boiler upgrade eight, effectively promote the prevention and control of air pollution.
Environmental issues waster heat recovery boiler for paper mill assembly Note: introduce a predetermined environmental protection boiler drum of the drum to be assembled longitudinal weld, the weld ring is assembled to the assembly welds and weld splicing head or both elements should satisfy the following requirements: the longitudinal seam or seal the actual welding seam edge deviation head sides of the steel sheet is not greater than 10% of the nominal thickness, and not more than 3mm; when the thickness is greater than 100mm, of not more than 6mm. Deviation of the actual edge seam on both sides of the steel sheet ring is not greater than 15% of the nominal thickness plus 1mm, and no greater than 6mm; when the thickness is larger than 100mm, no more than 10mm. Two abutting element or plate have different thicknesses and the edge of the book cut, treated according to the same plate thickness, the above-described nominal sheet thickness means; butt plate of different thicknesses, but with no thinning, the nominal thickness of the aforementioned finger planks . Any difference between the maximum inner diameter of the same cross-section and the minimum inner diameter of the drum should be not more than 1% of the nominal inner diameter. Angularity drum longitudinal seam should be no greater than 4mm. If the pressure detecting element via a weld joint defects found unacceptable, welding unit shall find out the reason, the development of a viable repair program to rework. Before welding defects should be completely removed. After welding, welding zone should be done appearance inspection and nondestructive testing. Heat treatment after welding element requirements, should be done after the welding heat treatment after welding. Rework the same position should not exceed three times. Repair parts, frequency and circumstances shall be deposited in the boiler repair product technical file. In the economic and environmental positive impact gas steam boiler
India is rich in coal resources and its coal production ranks in the world. In this context, coal-fired waster heat recovery boiler for paper mills are very popular in India. Many of the products produced by ZG boiler have been exported to India several times, such as the cfb power station boiler project. With the development of the times, the requirements of countries for environmental protection are also getting higher and higher. ZG boiler has paid attention to environmental protection very early. It is our mission to be the pioneer of environmental protection and energy conservation. ZG boiler has increased investment in environmental protection, research and development innovation, on the one hand to improve the performance of boilers, on the other hand to improve the environmental protection process of boilers and reduce pollution.
Noun interpretation shell waster heat recovery boiler for paper mill shell type boiler basic structure is the double jacket structure. Called outer cylindrical boiler shell, called the inner furnace tube (fire tube), the space between the inner ring, an outer tube filled with water, and the inner cylinder combustion chamber. When the medium pressure vapor, by the internal pressure of the boiler shell, furnace subjected to external pressure. Shell boilers and discrete and horizontal. The most commonly used fuel, gas boiler WNS horizontal internal combustion shell boiler. Shell boiler has the following characteristics: 1, containing water "pot" and light a fire in the "furnace" are contained in a housing - housing pot; 2, metal hearth (furnace) a small volume, surrounded by water, cooled extent, poor combustion conditions, must burn the fuel quality; 3, less heating surface, heating power or a small amount of evaporation, often water or pyrotechnic means to increase the heating surface tubes and the boiler capacity; 4, potshell larger diameter casing, open more porous, irregularly shaped, it is connected to the inner portion of the heated portions together from heat, temperature and the degree of thermal expansion, and thus the security housing is poor; 5, the boiler system is relatively simple structure, easy to transport installation, maintenance and inspection operation management .
