2. AQC boiler is composed of economizer, evaporator and superheater; PH boiler is composed of evaporator and superheater;
3. The AQC boiler is installed at the kiln head, and the exhaust gas is filtered into the AQC boiler through the sedimentation chamber; The PH boiler is installed at the end of the kiln, and in order to improve the heat exchange effect of the PH boiler, the PH boiler is equipped with a rapping device;
4. The heat exchange tube of AQC boiler is equipped with fins, which are used to increase heat exchange and reduce the wear of dust on the heating tube, therefore, the exhaust gas temperature of the boiler is 360, and the exhaust gas temperature of the boiler is 91; There are no fins on the heat exchange tube of the PH boiler, therefore, the exhaust gas temperature entering the boiler is 350, and the exhaust gas temperature leaving the boiler is 250.
5. AQC boiler is vertical and relies on internal pressure to circulate naturally; Circulate.

Anonymous users2024-02-06The brother above made a mistake and confused PH and SP.
In fact, PH cannot be regarded as a boiler at all, because the boiler must have a pot and a furnace, and the PH furnace is actually a heat exchanger.
The so-called AQC, PH, and SP are also names based on the cement process, which is not available in real boiler plants.
pH is generally a heat exchanger, and the saturated steam becomes superheated steam after being superheated by pH, and the steam turbine is used to do work. In the past, there were also cases where the water was heated by pH and then flashed to replenish the steam.
AQC is a standard waste heat boiler.
Therefore, the pH furnace is actually just a heat exchanger of the boiler.

The pH boiler is horizontal and relies on external pressure (water pump) to force circulation.
1. It is related to the waste heat temperature and flow rate, and of course, it is also related to the narrow point, end difference and close point temperature difference of the boiler design; >>>More
It is recommended to use a bag filter, the working mechanism is that the dusty flue gas passes through the filter material, and the dust particles are filtered down, and the filter material mainly relies on inertial collision to capture coarse-grained dust, and the fine-grained dust is mainly collected by diffusion and screening. The dust layer of the filter material also has a certain filtering effect. >>>More
The boiler is boiled and then watered, which usually causes the metal pipe of the boiler to cool sharply and burst, resulting in a large amount of steam leakage, which will not cause the furnace**. The factor of furnace ** is often that after the furnace is extinguished, the fuel in the pulverizing system is not cleaned in time, and the deflagration occurs after ignition, resulting in a sharp rise in the pressure in the furnace, which makes the furnace deformed and a large amount of coal ash leaks. Because the furnace is surrounded by a furnace wall composed of metal such as a water-cooled wall and an economizer, although the furnace is powerful, it generally rarely poses a direct threat to the person, after all, the water-cooled wall resists the shock wave generated by the furnace.

The main functions of the steam drum are: the connection hub of the three processes of working fluid heating, evaporation and superheating to ensure the normal water circulation of the boiler; There is a steam-water separation device and a continuous sewage discharge device inside to ensure the quality of boiler steam; There is a certain amount of water, a certain heat storage capacity, and the change rate of steam pressure is slowed down; There are pressure gauges, water level gauges, accident water discharge, safety valves and other equipment on the steam drum to ensure the safe operation of the boiler. >>>More
