Steel Industry

Steel Industry:

Bloom Engineering Company has provided combustion equipment/systems to the steel industry since the company was founded in 1934. Over that period of time, Bloom Engineering equipment has been used in all phases of the steel industry (primary end to finishing end) requiring combustion systems.

Steel Industry Case Studies
CS0101-1 Intelligen Retrofit

CS0105 Roof-fired Regenerative Solution for a Forge Furnace

CS0105 Roof-fired Regenerative Solution for a Forge Furnace

To accommodate an extremely tight envelope around a forge furnace, Bloom engineered a special roof-fired regenerative burner for a forge furnace.

CS0106 Low NOx Burner Retrofit

CS0106 Low NOx Burner Retrofit

Bloom specially engineered the Low NOx burners to match existing air connections and furnace wall penetrations reducing downtime during the outage.

CS0107 Regenerative Retrofit for a Reheat Furnace

In order to meet an aggressive NOx target, Bloom used a conversion kit to improve a competitor's burners.

    Frequently Asked Questions

      Question: What fuels can be used in Bloom burners?

      Answer:

      All Bloom burners can fire rich gaseous fuels. The vast majority of Bloom burners are capable of firing any flammable gaseous fuel and liquid fuel oils.


      Question: What is the fuel savings with regenerative burners?

      Answer:

      The fuel savings vary with the operating conditions. For example, firing natural gas with 10% excess air and a 2400°F furnace, the cold air efficiency is 31.8%; whereas, the regenerative efficiency is 73.4%.

          Application of Greenhouse Gas Reduction Technologies in Steel Rolling Mills

          Authors: Jens Hebestreit, Pittsburgh District Manager, Bloom Engineering Co.; David G. Schalles, Vice President – Technical Services, Bloom Engineering Co.

          The use of landfill gas as fuel for reheat furnaces is an excellent example of an alternative fuel source. The collection of landfill methane eliminates a major source of greenhouse emissions, while its use as an alternative fuel reduces the consumption of fossil fuels. Burners with reduced NOx emissions are currently so technically sophisticated that they can be installed and used without difficulty not only in new plants, but also in existing ones. Lower CO2 emissions can be achieved with the use of regenerative burner technology. Comparison to oxy-fuel firing will be addressed. The technology available to the metals industries for this purpose is described in this article. Recent examples of each technology will be discussed. Routes and initial steps towards adherence to future requirements are delineated.


          Selective Oxidation of AHSS and UHSS Steels Utilizing Direct Fired Burners Bloom Final

          Authors: Scott Brown, Direct Business Development, Bloom Engineering Co.; David G. Schalles, Vice President – Technical Services, Bloom Engineering Co.; Frank Beichner, Vice President - Engineering

          There is a great need to be able to convert existing Hot Dip Galvanizing Lines to be able to process Advanced High Strength Steel (AHSS) and Ultra High Strength Steel (UHSS) as well construct new process lines to bring additional capacity to market. By being able to use selective oxidation with direct fired burners to process Advanced High Strength Steel (AHSS) and Ultra High Strength Steel (UHSS) capital equipment costs and operational costs can be limited.  The steel can also be produced more quickly.
