Reasons For Selecting Bloom’s UNI-Heat Burner:

Bloom offered the customer substantial fuel savings to convert from existing tempered flame system to the UNI-HEAT® system. In addition, the customer was so happy with the temperature uniformity on the first retrofit that it only made sense to convert another furnace. The customer originally had 15.7 MM Btu/hr installed on the furnace.

    Frequently Asked Questions

      Question: What temperature uniformity could I expect with a Bloom burner and control system?


      Temperature uniformities of +/- 5˚F are possible depending on the specific application.

      Question: Does Bloom offer a heat treatment solution when a reducing atmosphere is required?


      Yes, typically air is used for the UNI-HEAT® jet, however, for a reducing atmosphere, recirculated products of combustion can be utilized.

      Question: What are the NOx emissions?


      It depends on the burner series, and operating conditions. Bloom feels very confident that our products can meet any current or future NOx requirements. Please contact Bloom for an evaluation of your operating conditions.

      Question: What is Bloom’s recommended method of air to fuel control?


      The UNI-HEAT® burner system will operate with excellent results using a pressure balance system. The small capacity 1150 LumiFlame® regenerative burner is pulse fired at the nominal input.
