Questions about burner pumps

It is very necessary to install a standby pump auto-start system for the burner cooling water pump; this system can protect the burner from being damaged. Proper operation of the burner relies on significant safety measures to ensure thorough mixing and reaction between the coal slurry and oxygen. If the amount of cooling water is too low or there are issues with burner protection, generally there are lower and upper limits set for flow regulation; as long as the flow does not exceed the upper limit, there is no problem.

I also think it is very necessary. The main reason is to protect the burner; in other words, even when the flow rate is low, the standby pump starting automatically still ensures that the burner is not damaged, otherwise it would be very dangerous. In fact, in our plant, the interconnection between flow rate and the gasification furnace is not necessary; what matters is pressure.

It is very necessary to set the burner cooling water pump to start automatically. The three-out-of-two interlock settings are high outlet temperature, high inlet pressure, and low inlet flow rate; when the pump starts automatically, the flow rate generally fluctuates upward, which does not cause the system to shut down

It is very necessary; it is required to protect the burner. The shell furnace burners are also equipped with the same protection system, and the emergency pump in the cooling water system of the circulating boiler water pump serves the same purpose.

Even if the system shuts down, the burner cooling water must not be stopped.

It is mainly used to protect the burner from being damaged; this item is expensive. It is extremely dangerous to have high-temperature and high-pressure gases flowing through after it gets burned out. Typical reasons for shutting down a two-out-of-three vaporization furnace are: a) low flow rate of cooling water to the burner, b) high pressure of cooling water from the check valve outlet to the burner. c. The temperature of the cooling water exiting the burner is very high. These parameters were selected because the rupture of the cooling water jacket and coils caused the high-temperature, high-pressure synthesizer to enter the cooling water system.

Reply: “Bottom bottom” refers to the minimum value at which something stops working; it generally denotes pressures, flow rates, temperatures, liquid levels, and other such minimum values – in other words, operation stops when these values reach a certain level. The explanation for “high high” is the same

Thank you, OP; I’ve noted it. Studying*……

Auto-start of the burner can prevent the burner from running out of water in the event that the pump operating it fails, allowing the gasification furnace to continue running; this is certainly necessary； There is a three-out-of-two interlock for the burner cooling water; this varies from plant to plant, but a flow rate of HH should not cause an shutdown.

Everyone’s chains are more or less the same; I’m wondering if they’re all Texaco burners. I saw that many people mentioned good things about them. I’m new here, so please give me some advice

The burner cooling water pump starts automatically when there is a low-pressure alarm in the burner cooling water main pipe; the standby pump then starts automatically； Fluctuations in the burner cooling water flow do affect system operation, but there is interlock delay protection in place ； If the pressure in the main burner cooling water pipeline is low, the interlock system that is typically in place is to open the emergency burner cooling water valve to supply water to the burner. In short, to protect the burner, it is sometimes necessary to ensure a supply of cooling water to the burner even during shutdowns. Of course, if there is a fault with the burner itself, such as a leak in the coil, it is necessary to shut off the isolation valves connected to the burner’s inlet and outlet to prevent safety accidents.

It is necessary for the standby pump to start automatically; as for alarms and shutdowns caused by fluctuations in water pressure, those are issues related to the settings for triggering alarms, starting the standby pump, and executing shutdown procedures.

1. There are various interlocks in the burner system, and these vary from one factory to another. As for the interlocks related to shutdowns, their purpose is to determine whether the burner is operating properly and to ensure the safety of the system. There are many ways in which such interlocks can be set up; for example, based on low inlet flow, low outlet flow, low inlet pressure, high or low difference between inlet and outlet flows, or high outlet temperature. 2. As for the safety-related interlocks in the burner system, things like automatic startup of backup pumps and interlocks related to emergency water tanks are essential. 3. The poster’s question, “If the cooling water flow rate to the burner is low and the standby pump starts automatically, then the flow rate at the burner coil will also increase instantly; in other words, this could cause the system to shut down…” is quite good. In fact, some interlocks in an ESD system do not activate immediately – they have a response time. That is, after an interlock is triggered, it takes a few seconds before it acts. If the conditions for activation are still met by that time, the interlock will function; otherwise, the pulse signal sent earlier is automatically canceled (this feature may not be available in burner systems). 4. In reality, when the standby pump starts automatically, it has little impact on the burner interlocks. The reasons are as follows: a) The startup of the standby pump only increases the inlet pressure. b) The inlet and outlet flow meters are located right next to the burner’s inlet and outlet, and water has very low compressibility; therefore, the startup of the standby pump does not significantly affect the interlocks related to high/low inlet and outlet flow rates. c) It has even less impact on other interlocks in the burner system.

Yes, starting the pump automatically is a measure taken for safety’s sake; one cannot simply ignore what happens after the vehicle crashes. Even in the event of a crash, water supply must continue as long as the burner has not been disconnected
