GarmIran Gas Burner GNG-90/3

Guide to Choose and Buy GarmIran Gas Burner GNG-90/3

Garm Iran Company, one of the activists in the production of heating equipment, can be considered as one of the first manufacturers of burners in the country. The time of purchase inquiry is announced. In general, when choosing a burner, in addition to the need to pay attention to the type of burner fuel, for various reasons it is necessary to consider the capacity of the burner about 20% more than the capacity of the boiler or heater combustion chamber. GarmIran model GNG-90/3 pays full attention to the diameter of the burner flame tube for the possibility of entering the above pipe in the boiler and the possibility of installing the burner in the boiler body. We suggest you buy a burner at the site of the Damatajhiz store.

Features of GarmIran Gas Burner GNG-90/3

• Garm Iran gas burners from 800,000 kcal model and above have electrical panels.
• Dividing the maximum heating power of gas burners by 9,200 gives the maximum amount of gas consumption of the burner in m³ per hour.
• Installing a gas filter with the appropriate size and working pressure after the gas quarter round valve and before the gas regulator and shock or solenoid valve gas valves is one of the first pieces of equipment required for the gas line in gas burners.
• If the gas line pressure of the burner is 2 pounds, it is necessary to use a balancer 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, if the gas supply pressure of the burner is higher than 2 pounds (15 or 30 to a maximum of 60 pounds), 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.
• In all hot gas burners in Iran, it is possible to install a butterfly valve and also to be able to connect to the BMS system.

Performance of the Gas Burner 

• A gas burner is designed for the combustion of natural gas and the volume or flow of gas fuel required in these burners, after passing through the gas filter is controlled by the solenoid valve, and the necessary air for their combustion is provided by a blower installed on the engine shaft. Turns.
• The inlet airflow is controlled manually or by a motor based on its capacity by an air damper installed in the burner body.
• The gas stream passes through a filter, mixes with the combustion air, and is ready for combustion. If the combustion air pressure is too low or the gas pressure is too high or too low, this is sensed by the built-in pressure sensors, and the burner is switched off by the pressure of the air and gas switches via the relay command.
• In terms of performance, gas burners are divided into types with blower or fan and also types without a fan (without sound). The burners used in apartment packages are of the type of gas burner without blower and without sound.

Adjust the fuel and air of the burner

• Complete combustion of the fuel is the result of fine-tuning the exact ratio of fuel to air. The more accurately this ratio is adjusted, the higher the burner combustion efficiency, and therefore less fuel is required. In small burners, the adjustment of the required air for combustion of the burner is done by a manual damper, but in large burners, this adjustment is provided by an automatic damper for the required combustion air. However, due to the fact that the air temperature of the engine room boiler and its humidity varies throughout the year, in large burners, the air damper must be readjusted in each season. Today, modern burners are equipped with an intelligent PLC control system that automatically adjusts the ratio between fuel and air throughout the day and all seasons.
• Due to the incompleteness of fuel combustion efficiency in burners and considering some heat losses, when choosing a burner, we consider the burner capacity to be about 20% more than the boiler capacity.
• For every 300 meters increase in height from the surface of the door or due to a decrease in air concentration, the fuel combustion efficiency of all types of burners is reduced by about 4%.
• The calorific value of each cubic meter of natural gas is approximately equal to 9200 K.cal.
• In Iranian hot gas burners, it is possible to change the main parts according to the taste and needs of the customer within the required standards.
