What Is The Use Of Economizer In Boiler

First, the boot 1, the operator must first have a fireman qualifications, so that the holder of the operation, the person in charge should carefully read the operating manual of the equipment, knowledge and proficiency in the safe operation of the method; 2, every time before starting to check the gas valve is open, otherwise, the burner does not work; 3, the power control button to start the control cabinet, the window displays the current digital case furnace pressure, the pressure level of the what is the use of economizer in boiler with reference to the judgment section control instructions; 4, after starting the burner, the first pre-blowing fan after 30-50 seconds sweep, and then open the gas valve; i.e., to establish a flame (combustion process with reference to the specific burner manual); 5, start and stop by the boiler burner controller is to issue an instruction start and stop according to a change in pressure, ( this feature is automatic) the operator should always observe the change in pressure when the abnormal phenomenon needs to stop immediately, the cease-fire; 6, boiler operator should always observe the water level during operation, in particular to ensure that fill the tank with water. The operator periodically to the boiler blowdown should ensure boiler water; 7, once the boiler during operation anomalies operator should shut down immediately after the new failure processing power; 8, burner for an operator to be used in the initial phase supply to determine before starting the motor forward, reverse, normal or not ignition (combustion engine fan case started ten seconds after the stop, alarm control box).

Porous materials have always been the main sound absorbing material, such as glass wool. The structural feature of porous sound absorbing materials is that there are many small gaps in the material. When sound waves are incident on the surface of the porous material, they can enter the pores, causing vibration of the air and material within the pores. The friction and viscous action of the air converts the kinetic energy (sound energy) of the vibration into heat energy, thereby attenuating the sound waves. The experiment proves that the sound absorbing material has better absorption for medium and high frequency, and the low frequency absorption performance is poor. Fangkuai Boiler uses a sound-absorbing technology combined with a porous material, and uses a sound-absorbing panel and a muffler chimney to effectively reduce the noise generated during what is the use of economizer in boiler operation.

This method is a method of adding a base, so that the what is the use of economizer in boiler is filled with water PH value of 10 or more. Corrosion resistance of the metal surface to generate a protective film to prevent corrosion of metals in dissolved oxygen. The lye used as NaOH, Na3PO4 or a mixture of both.

Heat recovery FAQ - Thermal Energy International

Boiler feedwater economizers are placed in the boiler exhaust stack and heat boiler feedwater after the deaerator and before the boiler. Condensing economizers will have exhaust gas temperatures of between 70°F and 130°F (roughly between 20°C and 60°C), whereas feedwater economizers typically exhaust at well over 200°F (over 100°C).

Why Economizer Is Used In Boiler

The economizer also prevents flooding of the boiler with liquid water that is too cold to be boiled given the flow rates and design of the boiler. A common application of economizers in steam power plants is to capture the waste heat from boiler stack gases (flue gas) and transfer it to the boiler feedwater.
