Polaris Answers: What is a heater? What is the purpose of installing a radiator? What are the advantages and disadvantages?
The heat exchanger which uses the low pressure exhaust steam from the steam turbine to heat the inlet air of the air preheater is called an air heater. Heater installation
Between fan outlet and air preheater inlet, it is also called front air preheater.
Install a fan heater to increase the temperature of the air entering the air preheater and increase the temperature of the walls of the air preheater, thereby preventing low temperature corrosion.
After using an air heater, the heat transfer temperature difference of the air preheater is reduced, the boiler exhaust temperature increases, and the thermal efficiency of the boiler decreases, which is more obvious than the use of hot air recirculation. CepMeanwhile, the unit heater uses low pressure exhaust steam from the steam turbine as a heating heat source. Increasing the amount of low pressure extraction steam improves the efficiency of the steam turbine cycle. The thermal efficiency of the boiler decreases and the efficiency of the steam turbine increases. The ability of the two to compensate for each other depends on the air heating temperature and the exhaust pressure. Generally, the increase in steam turbine efficiency cannot compensate for the decrease in boiler thermal efficiency. As a result, the overall efficiency of the power plant will decrease.
What size diesel generator is used for 10KW household appliances? Let me know if you know, thanks
Refunds can be made in this case.
Generally, if the car heater generator you purchased prhas quality problems or does not meet expectations, you can request a refund or exchange from the merchant.
However, it should be noted that if the car heater generator problem is caused by improper operation or irregular use, the merchant will not necessarily accept the refund.
It depends on whether your electrical device is an inductive load or a resistive load. Electrical devices with inductive load such as electric fans, water pumps, motors, etc., these devices usually have a starting current. the starting current is 3 times the rated current, 220V10KW. You must choose a generator of at least 30KW; devices with resistive load such as electric heating rods, water heaters, etc., these devices have no starting current. just choose a slightly larger one, like 10KW, you can buy 11KW or 12, 13KW is good.
