Method for implementing energy saving and environmentally friendly features a method of environmentally boiler boiler: the boiler flue gas heat recovery boiler is an important way of saving large flue gas calorific value, only the latent heat of vaporization of water vapor is sufficient to boiler feed water is preheated to above 100 ℃ not only can be used for boiler feed water, the excess water can also be used to heat domestic hot water. Fuel, boiler exhaust gas heat loss of about 8% to 16%, about 1% heat loss sewage, furnace heat 1 to 2%, 1% incomplete combustion, effective utilization of heat of about 80% to 91%, the flue gas includes N2 accounted 68%, Co211%, H2O16%, O24%, SO22PPM, NOx80PPM. If the exhaust gas temperature of 200 ℃, high total heat recovery through the heat exchanger, flue gas temperature can be lowered to 70C or less, the boiler feed water to raise to 20 ℃ 85 ℃, saving a lot of energy. Meanwhile, since the oil and gas, especially natural gas sulfur content less, the content of SO2 in the flue gas is very low, most of them are dissolved into condensed water discharged flue gas, the combined flue gas heat recovery devices are made of stainless steel, to ensure a reliable means corrosion resistance, and therefore the service life of the entire device more than 5-6 years. By monitoring, the indicators have reached the national environmental standards. Environmental regulations described boiler drum assembly welds should be: the drum longitudinal and circumferential weld head assembly or assembly welding seam characteristics weld two elements should satisfy the following requirements: the longitudinal weld seam or stitching head deviation of the actual edge on both 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.
After the fuel oil is sprayed into the furnace, it is very easy to mix with air and burn rapidly and exothermic rapidly. Compared with the coal-fired boiler with the same parameters and capacity, the thermal strength of the furnace volume can be doubled to 1046.6 × 10 kilo coke / m / m ·h. However, in order to reduce the heat load in the combustor area so as to avoid the overtemperature of the water wall tube in this area, the furnace volume is only reduced by about 1 / 3. Because the ash content in fuel oil is very little, it can not form slag on convection heating surface, so the flue gas temperature of furnace outlet can be up to 1300 ℃, and the pitch between tubes of convection heating surface can be reduced to increase the flow rate of flue gas, so as to increase the flow rate of flue gas. Heat transfer coefficient of heating surface, saving heating area and steel.
The depth of integration with the Internet industry, the party has been fast out of traditional industries inherent in the old ideology, gradually moving towards intelligent high-tech enterprise development. Chinese Good Technology, a leading research. With the continuous improvement of the Group's own pursuit of quick side with Tsinghua University, Xi'an Jiaotong University and Zhengzhou University entered into a collaboration, research cooperation agreement signed, and the establishment of upgrade Engineering Research Center - Laboratory cleaning boilers, combustion field exploration and try. This year, the group also reached with Hefei General Machinery Research Institute Xuedong academician cooperation, the establishment of "academician workstation", as the industry's cutting-edge technology research and innovation base. Confirmed eyes, fast boiler is rare good business.
