Riello Dual-Fuel Burner

Purchase Guide for Riello Dual-Fuel Burner

• RIELLO company was founded in 1920 in Italy and started its production activity by producing oil burners (for applications such as bakery ovens). It has developed and innovated systems throughout its history for optimizing its production line processes and equipment according to consumer needs and market competition.
  
  
• RIELLO Italian Company is one of the most reputable and leading torch manufacturers globally, using specialized personnel and advanced technology.

• In addition to being environmentally friendly, RIELLO's burners, by their global technology, are the most effective for combustion, reduce fuel consumption, generate the highest combustion efficiency, and be the least polluting.

• The burners produced by the RIELLO company use the highest fuel-air mixing technology, which results in the lowest possible noise.

• In the late 1980s, the company gradually established numerous branches in the United Kingdom, Germany, Belgium, Switzerland, etc., due to the wide acceptance of its burners throughout Europe.

• The RIELLO Dual-Fuel burner price will be checked and announced after the customer's request.

• When selecting a burner, be sure to consider the flame tube's diameter so that the flame tube can enter the boiler. 

• Customers can request that all RIELLO burners be converted to a modular or step-by-step model.

• In general, according to the RIELLO company catalog, when choosing a burner (RIELLO Dual-Fuel), it is necessary to examine the combustion curve relative to the combustion chamber pressure for each burner for various reasons.

• All RIELLO Dual-Fuel burners have a 1-year warranty.

• All RIELLO Dual-Fuel burners are equipped with a German protection system, switches, and contactors made in Germany.

• In the path of diesel fuel to the burner, diesel filters and nozzles or diesel nozzles must meet the technical specifications of the burner following its capacity.

• Among the first pieces of equipment required for gas, burners are installing a gas filter with the appropriate size and working pressure after the quarter gas valve and before the gas regulator and the shock or solenoid valves.

• If the gas line pressure of the burner is 2 pounds, a balancer should be used to adjust and balance the small changes in gas pressure of the gas burner supply with the required size and flow of the burner gas at the beginning of the gas line.

• Also, suppose the gas supply pressure of the burner is higher than 2 pounds (15 or 30 to a maximum of 60 pounds). In that case, it is necessary to install a gas regulator with the appropriate size, working pressure, and gas flow at the beginning of the burner gas line.

Operation of the Riello Dual-Fuel Burner

• In fan burners, the operation is based on the thermostat command of the boiler or heater and according to the burner relay schedule, so that first the burner aeration fan is turned on for about 30 to 60 seconds according to the fan relay command, and then the burner ignition transformer starts. It ignites, and then the burner fuel solenoid valve (gas, diesel, or fuel oil) is opened, and the fuel passes through the solenoid valve and enters the combustion chamber of the boiler or heater. Simultaneously with the presence of the transformer spark, a flame is formed in front of the burner flame spreader.
• After the formation of the flame, there is no need to continue the spark (electric arc). With the command of a photocell or ion, the operation of the igniter transformer is stopped. The burner continues its combustion action until the power turns off through the thermostat.
• Electromotorphene burners are based on the capacity of single-phase or three-phase burners and have 2900 rpm.

Riello Dual-Fuel Burner Air and Fuel Adjustment

• Complete combustion of fuel results from accurate adjustment of air/fuel ratio. the more accurate the ratio is adjusted, the higher combustion efficiency will be and as a result, the less fuel is needed. For small burners, adjustment of needed air is done by a manual damper, while for large burners, an automatic damper supplies combustion air.
• Given that the air temperature of the furnace boiler and its humidity varies during the year, the air damper of large burners has to be adjusted once per season.
• Today, modern burners are equipped with a PLC intelligent control system that automatically adjusts air/fuel ratio round-the-clock in all seasons of the year.

Given the incompleteness of fuel combustion in burners and some heat loss, when selecting a burner, burner capacity is selected 20% higher than boiler capacity.

• For every 300 meters of height from sea level, the fuel combustion efficiency of burners reduces by approximately 4% due to a reduction in air concentration.
• The thermal value of natural gas is approximately 9,200 Kcal per cubic meter.
• The thermal value of gas oil is approximately 8,500 Kcal per litter.
• The thermal value of gas oil is approximately 10,500 Kcal per kilogram.
