facility is consumed in the blast furnace, where in the form of coke it serves multiple roles including chemical reductant, furnace burden support, and acts as a fuel. The remaining 25% provides heat at the sinter and coking plants and, in the form of by-product gas, serves as an energy source (displacing other fuels) to

PC Boiler Oil/Gas Boiler Downshot Boiler CFB Boiler Conventional pulverized coal (PC) boilers are used in most thermal power plants as the most common way of burning coal in different types of boiler. Recent market requests higher steam conditions in order to minimize OPEX. Doosan has met this needs by boilers to ultra-

that are primarily fueled with coke oven and blast furnace gases, by-products of the steel-making process.The boilers are also fueled with natural gas when by-product gases are not available.The existing power generation system used treated lake water for boiler feedwater make-up.This water was heated to 240°F using low-pressure steam.

to 0.7 MW/h. This investment has led to significant drop in energy use and emissions and will be paid back in less than a year, says Norel Corneliu Jantea, energy project manager. During 2015, ArcelorMittal Galati also redesigned the air flow of two turbo blowers on blast furnace 5. A turbo generator, powered by steam produced

1.1.7.3.2 Blast Furnace Productivity and Performance. Blast furnace productivity depends on the fuel efficiency and flow of materials and gases through the dry and wet zones of the furnace. Therefore, good gas permeability of the burden and proper control of direct reduction are important for obtaining a high furnace productivity.

Explosive deslagging of the boiler has even been performed online, with the unit turned down to low load. Check out these videos of actual power plant boiler deslagging operations: video 1, video 2, and video 3. Outside the boiler, explosives have been used to clean such power plant components as scrubbers, fly ash silos, and precipitators.

Metso will supply automation for the Raahe steel mill's new blast furnace pulverized coal injection process and for Raahen Voima's power plant modernization to increase safety and reliability. Raahen Voima is currently building a boiler plant that will be equipped with Metso's automation systems and solutions.

For a range of natural gas compositions, encompassing the proposed European fuel supply standard, exact calculations of the stoichiometric flue gas volume are compared with the empirical EN 12952-15 calculations. The level of agreement is again very good. Validation on fuel oil has been limited to light fuel oils fired in gas turbines and boilers.
