Direct-fired machine is a common gas water heater, and its working principle mainly involves the process of gas combustion and heat energy conversion. Direct-fired machine is a process of heating water to the required temperature by generating heat energy through gas combustion. It is mainly composed of gas supply system, combustion system, heat exchange system, control system and smoke exhaust system.
The gas supply system is the gas supply equipment of the direct-fired machine, which usually includes gas pipelines, valves and gas supply pipes. The main function of the gas supply system is to provide gas fuel to ensure the normal operation of the direct-fired machine.
The combustion system is the key part of the direct-fired machine, which consists of gas nozzles, dampers, combustion chambers and ignition devices. The function of the gas nozzle and damper is to control the mixing ratio of gas and air to achieve the best combustion effect. The combustion chamber is the main area of gas combustion, and the ignition device ignites the mixed gas through sparks.
The heat exchange system is the core part of the direct-fired machine, which consists of heat exchangers, water circuits and water pumps. When the gas combustion generates high-temperature heat energy, the heat exchanger transfers it to the water flowing in the water circuit, thereby heating the water. Heat exchangers are usually made of copper tubes, which have good thermal conductivity and stable heat exchange effect.
The control system is the brain of the direct-fired engine, which monitors and controls the working state of the direct-fired engine. The control system usually includes temperature sensors, pressure sensors, controllers and programmable logic controllers. The temperature sensor is used to monitor the temperature of hot water, the pressure sensor is used to monitor the pressure of the system, and the controller and programmable logic controller adjust the opening and closing degree of the gas nozzle and the damper according to the feedback signal of the sensor, thereby controlling the supply and combustion effect of the gas.
The smoke exhaust system is the smoke exhaust device of the direct-fired engine, which usually includes chimneys, smoke exhaust pipes and smoke exhaust fans. Smoke is generated during the combustion process, and the function of the smoke exhaust system is to discharge the smoke to the outside to ensure the cleanliness and safety of the indoor air.
The working process of the direct-fired engine can be simply described as follows: First, the gas supply system provides gas fuel, and the gas enters the combustion chamber through the gas nozzle and damper of the combustion system, mixes with the air and ignites. The heat energy generated by the combustion is transferred to the water through the heat exchanger to heat the water. The control system monitors the temperature of the hot water and the state of the system, and adjusts the combustion effect as needed. The flue gas is discharged to the outside through the exhaust system.
In short, a direct-fired engine is a device that uses gas combustion to generate heat energy to heat water. It realizes the combustion of gas and the conversion of heat energy through the coordinated work of the combustion system, heat exchange system, control system and exhaust system. The direct-fired engine is widely used in households and industries for its high efficiency, energy saving and environmental protection.
