| Benefits |
The Minijet Burner has been developed to provide a cost-effective solution on applications where space is limited and thermal ratings are relatively low. Typical applications are tundish preheating station where several small burners are required to direct heat towards critical areas such as the pouring nozzles and impact pads or continuous kilns where firing patterns and zone configuration usually require a large number of small burners.
Other applications include small ladle heaters or small reheating, forging and heat treatment furnaces where high velocity cannot be used. The Minijet is also used in low temperature applications such as process drying or heating as well as ovens where they can be used in conjunction with recirculating fans. |
| High or medium velocity |
Depending on the process requirements, the Minijet can be fitted with a converging or parallel outlet to provide velocities of 150 m/s or 70 m/s respectively.
|
| Fuels, ingition and flame supervision |
The MJ Burner is ignited by means of direct spark. The burner is fitted with a sight glass and a port is provided for a UV scanner or flame ionisation probe to be installed. In order to start the burner automatically and supervise the flame permanently, Hotwork Combustion Technology can also supply flame management equipment if required. |
| Choice of outlet materials |
The standard Minijet Burner is fitted with a silicon carbide outlet but a cast refractory quarl is also available. Both are suitable for process temperatures up to 1450 oC. A stainless steel outlet can be used when temperatures do not exceed 1050 ° C. In situations where the burner is firing downwards, a lightweight vacuum-formed refractory fibre quarl can be supplied. |
| High turndown excess air |
The Minijet has a turndown in excess of 10/1 on ratio and an excess air capability of minimum 1000%. Fuels The Minijet Burner is suitable for natural gas and LPG.
