Linear natural gas hot blast furnace

1、 Burner characteristics and control process

1. Description of burner characteristics

★ AHLE burner can ensure good stability and efficiency when the gas flow is relatively low. The lowest pressure difference can be 0.5mbar.

★ When the burner uses gas (natural gas or liquefied petroleum gas) as fuel, the flue gas is clean and the emission of nitrogen oxides is low.

★ The burner does not need additional combustion air to save energy

★ The modular design of burner can be freely combined according to the power required by the equipment, and can be easily installed in various equipment.

★ The material can be changed so that it can be used under some special requirements.

2. Safety requirements for combustion system control

It has the functions of automatic small fire, automatic large fire, automatic temperature control, high temperature protection, fault alarm, etc; The control box is equipped with operating temperature display and high temperature limit protection device, as well as gas high pressure and low pressure alarm lights, burner failure and operation display. The system shall be equipped with the following safety protection: baffle differential pressure interlock, gas low pressure interlock, gas high pressure interlock, high temperature protection interlock, UV monitoring interlock.
