Parameters and heating in winter precautions oil-fired boiler oil-fired boiler should set this kind of boiler, I believe we will not feel strange, because the site has its relevant articles to allow them to learn and understand this kind of boiler, and at the same time, also to know the proper use and rational use of this kind of boiler, in turn, have a good economic benefits in the economic performance of the boiler. So, based on this, then, will continue to carry out this work, the study follows. Adjustments and adjust the size of the working pressure 1. conversion or oil-fired boiler control debugging: Under normal circumstances, turn a small fire is 0.9MPa, 0.8MPa turn the fire. Automatic startup and shutdown start furnace: when the operating pressure required is 0.8-1MPa, is adjusted to 1.02MPa shutdown, 0.82NPa start furnace. Overpressure alarm: it is generally set pressure than normal shutdown automatically comparing 0.05MPa. High level alarm: Usually when the setting is the distance of the upper glass sheet is less than 25mm, water enters the alert state. Extreme low water level shutdown: Boilers different manufacturers, it will be different on the set, however, the general principle is that each water tube boilers can not fall below the nozzle. Pump automatic start-stop control: water table is generally set in the center of the vertical and horizontal 25mm. The fuel pressure setting: heavy oil is 1.8-2.2MPa, light oil is 1.6-1.8MPa. Fuel temperature set: If the light oil is not heated, if a heavy oil, will have to control the heating. In addition, daily tank temperature of 60 to 80 degrees, the burner temperature is controlled within the range of 95 ℃ -110 ℃. Exhaust Temperature: oil-fired boiler exhaust gas temperature is 220 ℃ -240 ℃, Super Smoke alarm temperature is set to about 280 ℃. 2. The oil-fired boiler which signals and parameters should be set to indicate? Oil-fired boiler, and a parameter indicative of the signal which should be set for the oil flow into the oil feed pressure, chamber temperature, chamber pressure, the boiler water level alarm limit values and the like which, in addition, there may be some other parameters. Moreover, these terms of oil-fired boiler, is an important parameter, therefore, not be taken lightly. 3. The oil-fired boiler in winter precautions when heating oil-fired boilers, which on heating in winter, there are some precautions, which are as follows: the boiler room should take into account the possibility of development and expansion, between its subsidiary in position, should It does not interfere with the development of the boiler room. If the boiler room is in the factory, living area, it is generally a closed, but in their dust and the wind section, you can open layout.
Importance of continuous Feedwater equipment in Gas-fired Steam BoilerThere are two kinds of feed water methods for steam boiler, steam feed water and electric feed water. Steam water supply equipment mainly refers to water injector and steam reciprocating pump, usually acting as backup water supply equipment in boiler. Another commonly used electric feed-water method is through the electric centrifugal pump and vortex pump to feed the water. During the operation of steam boiler, the feed water equipment is usually required to have the active control function. The water level can be lowered to a certain azimuth to actively open the pump to feed the boiler, and the inlet water to a certain direction can also actively stop the pump. Hot water boilers can also be recycled according to in / out water temperature or heating conditions. So gas boilers are usually equipped Use an electric centrifugal pump or vortex pump instead of steam-powered feed-water equipment. The feed-water equipment in gas-fired steam boiler is a very important equipment in all boiler systems. It is responsible for supplying raw materials to steam boilers; allowing it to produce the steam it needs to be used. In the process of boiler operation, it is necessary for the water supply equipment to run synchronously so as to supply water to the boiler continuously, so that the boiler can get enough water supply to run normally and safely.
