fired tube oil boiler

fired tube oil boiler

Steam fired tube boiler furnace operating point first launched circulating pump equipment circulating pump outlet, into the furnace, the pressure released, and the system back to the oil pressure, make sure that in the positive practice mode. Circulation pump run for 30 minutes, after the stable operation of the system before it can enter the next step. Open gas pipeline manual valve steam boiler, burner launch button, natural gas burner into the furnace, and then burned, keeping the flame stable condition, is in the safe operation of the equipment. Incineration steam boiler, once the accident shut down if the phenomenon occurs, the device will take the initiative burner interlock protection status, should be promptly cut off natural gas pipeline, launched a purge function of the furnace, the furnace inside air replaced more than clean shutdown. System according to load requirements, temperature requirements and thermal oil outlet, the burner can be actively adjust the size of the amount of fire. Steam boiler heat exchanger is generally divided into two, one is directly touch the touch exchanger, and the other is the direct heat exchanger, which are separate apparatus for flue gas waste heat recovery, energy saving effect complete . Generally steam boiler practices can be simple progress through the transformation of energy-saving action, such as increasing the waste heat recovery equipment installed on, which is energy-saving advantages of steam boilers. Energy savings from the big side, is to promote the cause of saving the country, to say that small ways to create more profits for the company to save costs, the choice of one of the heat exchanger is a good way to complete energy policy.

Fast fired tube boiler is a very trustworthy business, whether it is the beginning of cooperation or boiler put into operation, such as a party soon have maintained cooperative attitude, patience, careful. To ensure long-term stability of the latter part of the boiler operation, fast boiler technician fireman's gave us a free people to do the training, precautions and reduce the accident rate method full guidance boiler operation. --customer feedback

Boiler burner selection techniques to select the type of burner nozzle atomization or gas burner and furnace fired tube boiler performance according to the structure, which is the most important point. Today we take a closer look. Burner output should match the rated output of the boiler, choose a good shape of the flame, such as length and diameter so as to adapt the furnace structure. The required combustion air is supplied from the root flare fuel gas and air or oil mist uniformly mixed rapidly, to ensure complete combustion. The rated output of the boiler and boiler efficiency is determined, the fuel consumption is calculated, and then selected according to power a single burner arranged to determine the number of burners. Increase the number of burners, in favor of the atomization quality assurance wind oil mix, but too many, and not easy to operation and maintenance, will give burner arrangement difficult. Adjusting the burner to a large extent, be able to adapt to changes in boiler load, to ensure complete stable combustion under different conditions. Fuel atomization less energy consumption, adjusting the wind resistance of the device to be small. Effects of smoke and noise emissions must comply with environmental standards, the main emissions must be below national requirements, should use low-noise and low burner. There are integral and split two ways boiler burner assembly. I.e. monolithic burner body, the burner and a combustion air blower system (including an oil pump, a solenoid valve, a servo motor or the like) into one; split i.e. burner body (comprising a combustion head, oil or gas systems), fans and combustion burner control system (including the control box, fan thermal relay, AC contactor, etc.) are each independent three-part system, according to the specific requirements of the boiler and user choice. We should use a simple structure, reliable operation, easy to adjust and control the repair, easy to implement automatic control of the combustion process in the burner. Respond burner brand, performance, price, and service life of comprehensive comparison. In addition to the burner air pressure to be considered to overcome the resistance of the outer boiler, economizer and also to overcome the resistance of the flue gas system.

Combustion Adjustment of dual-use oil and gas fired tube boilers (Skills) boiler firing was successful, the load can be adjusted to normal operation. At this point, we should always observe the furnace combustion, if there is a bad oil and gas atomization, beating the flame, the flame hit the furnace and the exhaust gas temperature is too high or too low and so, it is timely for oil pressure, oil temperature, of steam, wind, air pressure, steam pressure hanging line adjustments to ensure safe and economic operation of the boiler. Size and load size of hydraulic, pneumatic boiler related to the oil pressure adjusted by adjusting the back pressure or fuel burner to achieve the size, by adjusting the air pressure to achieve the degree of opening of the valve. Adjust the amount of oil, air pressure adjustment load, at the same time, air volume control, must be synchronized to ensure a reasonable match of oil and the amount of wind, so as to achieve economic operation of the boiler. 1, the combustion method of determining boiler fuel gas: C02 content is determined from the flue gases and excess air ratio (1) the combustion quality (2) determines the length of the flame from the combustion quality (3) from the flame color and smoke color determination 2 is good or bad combustion, fuel combustion boiler adjustment method: the normal combustion, furnace flame stability was white orange, generally rumble, or if the flame beating abnormal sound, should adjust the fuel and air volume. If the adjusted still no improvement, it should identify the cause flameout, the measures to be taken and re-ignition.
