Parameters and heating in winter precautions oil-fired oil or water tube boiler for fertilizer plant 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.
The main factors affecting small type gas steam oil or water tube boiler for fertilizer plant steam boiler thermal stability of gas ignition is not difficult to establish a stable small fire signal, the root cause is a small fire detectors can not detect normal to the fire. Gas-fired steam boiler burner underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reducing user fees biomass boilers categories: biomass boilers horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass steam boiler, biomass hot water boiler, biomass oil furnace. Function gas boiler the ignition system that ignites the mixture of air and fuel, its main components are: the ignition transformer, the ignition electrode, a high voltage electrical cable fire. A more secure electronic ignition system called ignition pulse, is widely used Zhuoyi energy saving gas boiler manufacturers. Which facilitate saving, can simply press a finger, and safe, does not occur due to unexpected accidents occur flame, once the stall state occurs, the control system can close the solenoid valve, off the gas passage. Small fire detectors use the ionization fire detection, and requires effective contact area of the flame, the flame stability and proper size, the gas pressure must be controlled within a very strict range. If the ignition gas pressure is too high, too long a small fire flame is moved beyond the detection range of the small fire detection probe, the system will not be mistaken for a small fire; if the gas pressure is too small, the gas will be firing too small and the boiler the blast very, very easy to blow out the flame, the ignition is not possible. Also, fire gases found a small pressure regulator valve regulating performance is not good, fine adjustment can not be achieved. Stability is also related to a small fire and the ratio of the size of the boiler furnace pressure boiler feed valve. The damper is too large or too small can affect the stability of the flame is ignited and the flame, furnace pressure will lead to extinguish the flame. In order to ensure the accuracy of fire detection, fire detection, we can adjust the small depth of insertion of the probe, the position of the fire detection probe in the correct position, in order to more effectively detect small fires flame.
Recently, the Jiangsu provincial government issued "Jiangsu Provincial Environmental infrastructure building program for three years (2018-2020 years) notice", the "notice" clearly states that, by 2020, the province's natural gas power generation installed capacity reached 20 million kilowatts, total coal consumption reduce 32 million tons more than in 2016, non-fossil fuels in primary energy consumption to 11%. Encourage waste incineration plants, cement plants, coal-fired power plants, organic fertilizer plant and other social resources co-sludge treatment and disposal, and given tariff or price subsidies.

The main components of the oil or water tube boiler for fertilizer plant: boiler lot of people know, but do not always understand the boiler, even customers who have purchased the boiler is not very understanding of what are the component parts of the boiler. Today to look at a detailed analysis of boiler components which mainly consists of: 1, drum. Its role is to collection, storage, and supplementary steam feedwater purification. In water-tube boilers usually 1 to drum 2, the drum is called a steam drum (drum), referred to below water or mud drum drum. The inner drum has a uniform distribution of the feedwater tank, and the water separation means the continuous blowdown apparatus. Internal boiler drum water tube assembly and a separator and the like. The outer drum containing the main steam valve, the sub-steam valve, safety valve, air valve, water level gauge, sewage connection pipe and pressure gauges. One end of the head or top of the drum was Manhole. One end of the drum head with the open manhole bottom with periodic discharge means. In many riser and downcomer (bundle) connected to form the entire structure of the elastic member between the upper and lower drum. 2, water wall heating surface. It is disposed around the furnace radiation heating surface. Boiler tube made of φ51 × 3 ~ φ63.5 × 3.5mm in industrial boilers generally used rust, while the main heating surface of the water tube boiler. Radiation heating surface absorption of radiant heat and flame shield the furnace wall, and thus play a protective role in the furnace wall; the same time, as more endothermic, the furnace temperature can be reduced, as well as to prevent burning effect coking coal seam. 3, header. It is a collection of tubes arranged in the main element is coupled, and a dispensing action of water drawn, its location has upper header and a lower header or inlet header and the outlet header bin of. A header welded seamless steel pipe is generally greater diameter and two end caps. In recent years, some manufacturers shut spinning tube ends, substituted welded end cap, a more rational structure. 4, the convection heating surface tubes. Convection convection bank known as the drain pipe, located between the upper and lower drum, generally by a boiler φ51 × 3mm steel composition, the main heating surface of the water tube boiler. In order to sufficiently absorb heat, convection bank usually intermediate, separator trap wall consisting of a flue or turns back and forth, increasing the flow of flue gas, and smoke at high speed across tube bundles. 5, the pyrotechnic heating surface tubes. Smoke tube heating surface is the main fire tube smoke-tube boiler and a combination boilers, its role is as high temperature flue gas generated from the combustion furnace flows through the inner tube, the outer pot of water continuously on the heating tube, it gradually becomes steam (or hot water). Smoke tube is typically mounted pot shell, fixed to both ends connected to the tube plate by welding or expansion. Because of its limited number of installations of the boiler shell, plus content of the tube is easy to plug fouling, easy outer tube fouling, it is not practical for large boilers. 6, the superheater. Economizer and air preheater, which belong convection heating surface. Superheater convection superheater addition, there are radiation superheater, economizer and a preheater rest are mounted boiler backpass. Their role in the main exhaust gas temperature is further reduced, improving the thermal efficiency of the boiler.
