1锅炉基本情况一台20t/h燃油蒸汽锅炉,采用德国SKV150转杯雾化燃烧器,燃烧器燃用重油为提高燃油温度,降低黏度,提高雾化效果,重油管路使用了电伴热。轻油系统有储油罐、日用油箱、油泵、阀门和管路组成。2改造方案根据目前锅炉燃料供应情况,计划将锅炉燃料从重油更换为油气两用。为了适用双燃料,安装新的燃烧器配气环和相应的燃气阀组(包含点火控制,风气比控制),既能够烧重油,又能实现燃烧天然气的功能,改造方案包括:
A boiler basic situation A 20t / h fuel steam boiler, the use of Germany SKV150 rotor atomized burners, burners burning heavy oil to increase the fuel temperature, reduce viscosity, improve the atomization effect, heavy oil pipeline using electric heat tracing. Light oil system has storage tanks, fuel tanks, pumps, valves and piping components. 2 Transformation Scheme According to the current boiler fuel supply, it is planned to replace the boiler fuel with heavy oil for oil and gas purposes. In order to apply dual fuel, the installation of new burner gas distribution ring and corresponding gas valve group (including ignition control, air-to-air ratio control) can not only burn heavy oil, but also realize the function of burning natural gas. The reconstruction program includes:
