What does the Fangkuai boiler tell you about instrument activity analysis? What is the effect of instrument activity analysis? The operation of the boiler is reflected by the instructions of various instruments. According to the indicator data of the instrument and its changing trend, it is the analysis of the instrument activity to analyze whether the boiler's working condition is normal or not. The normal operating parameters of the boiler are measured by various thermal monitoring instruments in various parts. The vehicle data include pressure, temperature, flow rate, water level, current, etc. In normal operation, by monitoring the operation of these parameters, we can analyze and judge the operation condition of the passageway, and when the accident occurs, we can also pass the Abnormal data changes to analyze and judge the location and nature of the accident, this timely handling of the accident to create conditions. The surge of induced fan is due to the excessive differential pressure in the inlet and outlet of its static blade. The differential pressure of the inlet and outlet of the stator blade is influenced by the resistance of the pipe, and the same induced fan is more prone to surge when the resistance of the static blade opening pipe is large. The static blade opening of the induced fan produces the corresponding wind pressure and flow rate. When the pressure and flow rate produced by the fan are greater than or equal to the resistance of the flue gas pipe, the fan can work stably without surging. When the resistance of the pipe increases, the pressure flow at the outlet of the fan can not overcome the resistance of the pipeline system. The force reverses the current. When the pipe resistance is reduced to the fan outlet pressure, the flue gas flows downstream. The smoke flows back and forth in such a way that it is surging. Therefore, when the resistance of wind-smoke pipe is large, it is more prone to surge when the output force is not enough. The influence of starting and stopping pulverized coal production system on boiler combustion condition is analyzed. As a result of the three-time air belt powder, the furnace fuel quantity increases / decreases, and the oxygen content increases / decreases relatively when the pulverized coal production system is started / stopped. When the pulverized coal making system starts for a long time, the boiler flame length is long, the furnace fire filling degree is good, and vice versa; under low load, the multiple pulverizing system operates or completely stops the pulverizing system, especially to prevent the flame from suddenly extinguishing. Once What is the cause of duct clogging? How to prevent it? Reasons: 1) the burner is blocked by coke or the inlet of the burner is partly blocked by small oil gun. 2) too many impurities in pulverized coal, too high speed of pulverized coal feeder, too heavy pulverized coal and too low primary wind speed. 3) the speed of powder feeder is too high. Too much powder to blow away in time. 4) the wind pressure is too low once (the wind door is not open or the opening degree is too small), do not take away powder. Preventive measures: 1) according to the speed of the powder feeder and the load of the unit, the corresponding primary air pressure should be adjusted in time, the speed of the powder feeder shall not be greater than 700 rpm, the primary wind speed of each unit shall be kept at 25 ~ 30 m / s, and the mixing temperature of the primary air and powder shall be controlled at 180. At ~ 250 ℃, the primary wind pressure depends on the load and coal quality, and the range of variation is in the range of 2.5~3.8kPa.2) it is found that the primary wind speed is too low. When the primary air temperature is lower than the normal value, the primary air velocity and the primary air temperature corresponding to the speed of the powder feeder should be reduced in time. 3) the boiler oil tank stop powder feeder should fully blow the tube. Blow away the powder from the powder tube. 4) scorch or clog the fire nozzle and try to get rid of it. Which causes the induced fan vibration? 1) motor bearing oil shortage, resulting in bearing wear and vibration; 2) coupling installation center is not good; 3) induced fan stall surge; 4) induced fan ground angle bolt Loose; 5) blade ash or wear, out of balance.

Working principle and structural characteristics of steam boiler

Steam boiler has brought great convenience to industry. Steam boiler has driven the development of the times. The following is a brief introduction to the structural characteristics and working principle of steam boiler. Steam boiler is a machine that mainly produces steam, and many people use it, but many of them do not know much about its structure and working principle. It makes use of coal, oil, natural gas and other water-tube steam boilers with limited capacity and pressure. There is a large desire to space, and easy to arrange, steam boiler in a variety of forms. Water is heated in the drum into steam, and the heat emitted by fire in the furnace is the principle of a steam boiler. Work of steam boiler Principle:

1, the heat generated by pulverized coal combustion in the furnace is first absorbed by the water wall through radiative heat transfer, and the water boiling of the water wall is vaporized, producing a large amount of steam into the steam drum for steam separation (except for direct flow furnaces). The separated saturated steam enters the superheater and continues to absorb the flue gas heat at the top of the furnace and the horizontal flue and the tail flue through radiation and convection, and enables the superheated steam to reach the required working temperature. The steam boiler for power generation is usually equipped with a reheater, which is used to heat the steam after the high-pressure cylinder does work, and the reheat steam comes out of the reheater to go back to the middle, and the low-pressure cylinder continues to do the work to generate electricity.

2. When the pulverized coal stove is working, The position of the center of the flame will affect the amount of evaporation, generally speaking, if the center of the flame is low, the amount of evaporation will be large, and the position of the center of the flame will also affect the temperature of the superheated steam or reheated steam, as well as the high value of the flame center and the small amount of evaporation. When the flame center is low, the superheated steam, especially the reheated steam temperature, will be low and vice versa.

3, the arrangement of burners, as far as coal powder furnace is concerned, there are many kinds of combustion modes, such as front and rear wall, tangential combustion, double tangential combustion, and so on, each of which has its own characteristics. The influence on steam can not be directly determined because the same furnace can not apply the above-mentioned arrangement methods at the same time.

Boiler basic knowledge and principle: as a heat carrier, pump forced circulation of liquid phase, then return to reheating, direct-flow special industrial furnace. Widely used in foundry sand molds such as petrochemical, textile, printing and dyeing, plastics, rubber, food processing, wood processing, asphalt heat, carton production, vegetable dehydration, drying and so on. Boiler is an energy, safe, heating equipment, is an ideal alternative to steam boiler products. The working principle is that the oil heater (endothermic) (organic heat) which is transported to the various thermal equipment after heating, the heat conduction (heat energy release), and then back to the furnace, forming a closed circle in the sense of meaning. In order to achieve the purpose of heating in the process of education. Performance and characteristics: 1, low pressure and high temperature. With the increase of temperature, the viscosity of the oil will continue to decrease the resistance of the system, but also reduce the working pressure, more conducive to safe operation and safe operation. Steam boiler is a high temperature and high pressure plume. 2 the heating system adopts hot water and equipment inlet and outlet temperature of 20? 30 degrees closed-circuit forced circulation heat can be recycled repeatedly there is no waste thermal efficiency is high energy-saving effect is remarkable. (3) the pressure of the heating system is low and the requirements of the pressure equipment and its system will also be reduced accordingly. Therefore, the steam pot required by the production process is accordingly reduced. The furnace is simple and the investment cost is low. 4, the thermal efficiency of various loads can be maintained at an optimal level, and can be adapted to the production of heat load requirements of the following types of 320 degrees, temperature can be accurately adjusted and controlled. 5, heaters to increase two to three times the cycle can provide a wide range of temperature processes for a variety of equipment to meet different temperatures that greatly reduce the need for equipment investment.
