What parameters are debugged for oil fired boilers, and how to adjust the temperature gauge of oil f

I don't know how big the boiler you are talking about, but let's talk about the parameters to be debugged for small oil-fired boilers (, the burner is a Weiso burner.

Conversion pressure control and debugging of large and small fire (such as turning to low fire and turning to large fire).

Normal automatic furnace shutdown and automatic furnace start pressure control and debugging (if the working pressure requires, adjust to stop the furnace and start the furnace).

Overpressure alarm, furnace shutdown pressure control and debugging (generally about higher than the normal automatic furnace shutdown pressure setting).

High water level alarm setting (generally adjusted to about 25mm from the visible edge of the upper part of the water level gauge).

Low water level alarm and automatic furnace shutdown setting (generally adjusted to about 25mm from the visible edge of the lower part of the water level gauge).

Limit low water level shutdown (according to different manufacturers of boilers, some have a separate electrode control device on the top of the pot barrel or shell, and some are together with the water level control device, the shell boiler shall not be lower than the maximum fire limit in principle, and the water tube boiler shall not be lower than the falling nozzle).

Automatic start and stop control of the water pump (generally adjusted to about 25mm above and below the center of the water level gauge).

Fuel pressure setting (generally heavy oil pressure is adjusted to about left, light oil is adjusted to left and right).

Fuel temperature setting (light oil does not need to be heated, heavy oil heating control temperature: the daily fuel tank is generally set at 60 80 degrees, and the temperature controller on the burner is adjusted to about 95 110, which is adjusted according to the heavy oil model).

Exhaust gas temperature control setting (general oil-fired boiler exhaust gas temperature is set at 220 240, over-smoke temperature alarm is set at about 280, and the smoke temperature exceeds the standard must be cleared of soot or scale or flue gas short circuit fault).

The debugging of various interlocking protection controls (flame-out protection, flame detection protection, over-smoke temperature, low water level and extremely low water level, over-pressure, etc.) will send out sound and light alarms and stop the furnace, and the furnace can only be started after manual reset; The boiler will not be able to be started if the burner is turned on, the oil temperature is low, etc.; The high water level generally only emits sound and light alarms and does not stop the furnace).

In addition, it is necessary to adjust the damper of the large and small fire of the burner, which should be adjusted according to the variety of oil and the form of the boiler, etc., there is no fixed parameter, and the adjustment is qualified to the following conditions: the flame burns stably, yellowish-white and not dazzling, the chimney has a slight visible flue gas (not obvious), and the large and small fire does not go out when converting, and does not emit black smoke. According to my experience, the opening of the small fire damper is generally 23 30°, the opening of the large fire damper is 45 60°, and the switch of the large fire solenoid valve is controlled at about 40°.

It is recommended that you use a small gas or oil-fired steam boiler, which can produce 170 high-quality steam within half an hour, which absolutely meets the heating requirements of general large villas.

How to adjust the temperature gauge of the oil-fired boiler, hello dear! 1. Setting of starting temperature: plug the power cord of the thermostat into the mains 220V power socket, and after there is a digital display on the panel, press the "+" button or "—" key of the starting setting to set the starting temperature, and the temperature displayed on the meter is the starting temperature of the circulating pump.

2. Stop temperature setting: press the "+" button or "-" button to stop the setting to set the stop temperature of the circulating pump, and the temperature displayed by the head of the meter is the stop temperature of the circulating pump. 3. Temperature setting of the temperature control of the temperature alarm:

In general, the starting temperature is higher than the stopping temperature, that is, starting at high temperature and stopping at low temperature; If the settings are reversed, the controller will not work properly. The opposite is true for users who require a low-temperature start, i.e. the starting temperature is lower than the stop temperature. 4. When you need to force the circulating pump to start or stop, you need to press the "manual" button, when you press the "manual" button once, the "start", "stop" indicator and "actual temperature" of the circulating pump start to flash, indicating that the controller has entered the manual working state; Press the "Manual" button again, and the circulating pump will stop working; When the experiment is completed, it is necessary to press the "auto" button, and only by pressing the auto button can the controller return to the automatic state to play the role of automatic temperature control.

5. Connection of the controller: insert the plug of the controller into the 220V power supply, and the circulating pump below 2000W is directly inserted into the socket of the controller, and the circulating pump above 2KW needs to be converted by intermediate relay. Install the temperature probe on the upper Yuno water pipe of the boiler, or if you choose to start at a low temperature, you need to install the temperature probe on the return pipe of the boiler.
