As a clean fuel, blue-coke produces lower levels of SO2, NOx, dust, and heavy metals during combustion compared to raw coal. Its post-combustion emissions meet environmental standards and have been recognized as a clean energy source by the National Development and Reform Commission and the Hebei Provincial Government, without consuming coal usage quotas. Blue-coke has a high calorific value of 6,200 kcal/kg, an annual production exceeding 100 million tons, and a highly competitive price. However, due to its low volatile content and unique carbon particle structure, it faces challenges in ignition and complete combustion in conventional boilers, significantly limiting its widespread application in industrial boilers. The blue-coke boiler modification by Shaanxi Fandelī Boiler features a simplified water circulation system and a rationally designed pressure-bearing structure, ensuring safe operation under proper water quality conditions. The combustion equipment of the blue-coke boiler adopts a quick-installation grate, manufactured and assembled in the factory, and can be directly installed on the foundation after transportation to the site. With its rational and compact structure, low steel consumption, and superior performance, weight, and dimensions compared to domestic boilers of the same capacity, it demonstrates significant advancements. Supply of blue-coke boilers: energy-saving and environmentally friendly fuel boilers. I. Criteria for Evaluating Modification Results Generally, the success of a boiler modification is judged based on steam pressure or steam flow. 1. Steam Pressure: The modification is evaluated by comparing the time taken for the boiler to reach the required steam pressure from a cold start before and after the modification. 2. Steam Flow: Professional institutions use specialized equipment to measure the steam flow under rated or operational conditions. The modification is deemed successful if the post-modification steam flow meets or exceeds the pre-modification measurements under the same conditions.
