Gas Burner for Boiler Room by Garm Iran Model GNG-90

Expert Guide to Buying Gas Boiler Burner with 110000 Heating Capacity

The Garm Iran Gas boiler Burner Model GNG-90 is one of the gas burners for boilers from the Garm Iran brand, produced by the company with natural gas as fuel and a capacity of 110,000 Kcal/hr.
Garm Iran Company is an active manufacturer of heating equipment and one of the first burner producers in the country, with its work in boiler burner production dating back to the early 1980s. When selecting a burner, in addition to considering the type of fuel, the burner's capacity should be approximately 20% higher than the capacity of the boiler or the heater combustion chamber. When choosing the Garm Iran Gas Burner Model GNG-90, pay close attention to the diameter of the burner flame tube to ensure it fits into the boiler and can be installed correctly on the boiler body.
At the DamaTajhiz reference and sales platform, the technical specifications and guaranteed prices of various gas burners are provided with official warranty to ensure an optimal and smart purchasing experience. When selecting and buying burner, always check the technical specifications of different models and determine the fuel type of the product.

Features of Garm Iran Gas Burner Model GNG-90

• Garm Iran gas burners from 800,000 Kcal and above come with an electrical control panel.
• The maximum gas consumption of the boiler burner in cubic meters per hour is obtained by dividing the burner's maximum heating capacity by 9,200.
• Installing a gas filter with appropriate size and working pressure after the quarter-turn gas valve and before the gas regulator and solenoid or gradual gas valves is one of the essential first components in the gas line of gas burners.
• If the gas supply pressure to the burner is 2 psi, using a balancer to adjust and balance minor variations in the supply gas pressure with the required gas flow for the burner is essential at the beginning of the gas line. Also, if the supply gas pressure is higher than 2 psi (up to 15, 30, or maximum 60 psi), installing a gas regulator with suitable size, working pressure, and gas flow is required at the start of the burner's gas line.
• All Garm Iran gas burners allow the installation of a butterfly valve and connection to a BMS system.

 GNG-90 Gas Boiler Burner Operation

• The gas burner is designed for burning natural gas. The required gas flow passes through a gas filter and is controlled by a solenoid valve. The necessary combustion air is provided by a blower mounted on the motor shaft.
• The airflow is controlled manually or by a motor-driven damper installed in the burner body according to its capacity.
• The gas flows through a filter, mixes with combustion air, and becomes ready for ignition. If the combustion air pressure drops below a certain level or the gas pressure deviates from the required value, sensors detect the change, and the burner shuts off via air and gas pressure switches through relay commands.
• Gas burners are categorized into forced-draft (fan) or non-fan (silent) types. The burners used in apartment packages are silent gas burners without a fan.

Fuel and Air Adjustment of Boiler Burner

• Complete combustion is achieved by precisely adjusting the fuel-to-air ratio. The more accurately this ratio is adjusted, the higher the burner's combustion efficiency and the lower the fuel consumption. In small burners, the required combustion air is adjusted via a manual damper, while in large boiler burners, an automatic air damper provides the necessary combustion air. Since the boiler room air temperature and humidity vary throughout the year, in large burners, the air damper must be readjusted each season. Modern burners for boilers are equipped with a PLC intelligent control system that automatically adjusts the fuel-to-air ratio throughout the day and year.
• Considering incomplete combustion efficiency and some heat losses, the burner's capacity is chosen approximately 20% higher than the boiler's capacity.

• For every 300 meters increase in altitude or due to reduced air density, the combustion efficiency of all burners decreases by about 4%.
• The calorific value of one cubic meter of natural gas is approximately 9,200 Kcal.
• In Garm Iran gas burners, it is possible to modify main components according to customer preference within standard limits.
