摘要

显示了在乌克兰运行的锅炉TVH-8M, TVH-8和NYYSTU-5现代化的可能性,其技术和经济指标提高到现代欧洲水平。开发了锅炉现代化项目,其中包括在不增加锅炉整体尺寸的情况下,重新设计现有锅炉对流轴的受热面,使用直径为32 x 3毫米的管道对流部分,并用开发的新型MPIG-3替换燃烧器装置。工业实施结果表明,TVH-8M (TVH-8)型锅炉在负荷运行范围内的效率为94 ~ 96%,NYYSTU-5型锅炉的计算效率为92 ~ 94%。实验证明,当安装特殊的校准喷嘴时,而不是在燃气燃烧器的集热器上钻孔,可以在整个使用寿命中保持喷嘴几何形状(天然气燃烧器消耗取决于压力)不变。展示了仅更换喷嘴装置时,在MPIG-3型槽底扩散燃烧器中燃烧沼气和天然气与氢气混合物的技术可能性。圣经17,图6,表1。

ENERGY EFFICIENT EQUIPMENT FOR MODERNIZATION OF THE GAS BOILERS POWER 0.1-30 MW
The possibility of modernization of boilers TVH-8M, TVH-8 and NYYSTU-5, operated in Ukraine, with the increasing of their technical and economic indicators to the modern European level is shown. Projects of modernization of boilers have been developed, which consist in redesign of heating surfaces in convective shafts of existing boilers without increasing their overall dimensions with using convective part of pipes diameter 32 x 3 mm and replacement of burner devices by developed new type MPIG-3. It is shown that the results of industrial implementations achieved efficiency of boilers type TVH-8M (TVH-8) 94-96% in the operating range of their load and obtained the calculated efficiency for boilers NYYSTU-5 92-94%. It is experimentally proven that when installing special calibrated nozzle, instead of drilled holes in the collectors of gas burners, it is possible to keep the nozzle geometry (natural gas burner consumption depending on pressure) unchanged throughout the service life. The technical possibility of combustion of biogas and mixtures of natural gas and hydrogen in the slot bottom diffusion burners of the MPIG-3 type, when replacing only the nozzle apparatus is shown.
