How to provide boiler thermal efficiency thermal efficiency of the hot selling coal steam boiler manufacturer has the following methods: low-pressure boiler at the factory has been designed considering the problem of thermal efficiency of the boiler, the flue gas from the device or change little aspects of energy-saving possibilities, it is best to start from the energy-saving operation (here talk recovered water vapor condensation method). The current design thermal efficiency of domestic low-pressure boiler is generally 70 to 90%, generally the actual operation of the thermal efficiency of about 60 to 80%, some even below 50%, a small low pressure industry as long as the operation, maintenance properly, can meet the design thermal efficiency of manufacturers. I think the management and operation should pay attention to the following points: First, the boiler flue gas temperature monitoring. Typically the maximum exhaust heat loss is loss, it is important to good control of exhaust gas temperature, exhaust gas temperature is generally low pressure coal-fired boiler of 150 ~ 180 ℃, fuel boiler exhaust gas temperature is 210 ~ 240 ℃, so when the boiler to find out why when the exhaust temperature is too high and promptly eliminated. Coal-fired boiler flue gas temperature is too high reasons are: high furnace pressure; shorting smoke; thick soot on the heat pipe; thick scale pot like. High temperature fuel exhaust reasons are: 1 air not adjusted oil, the oil is not completely burned in the chimney the secondary combustion occurs aft; 2 soot too, the need for timely cleaning; 3 shorting smoke; 4.... thick scale; Second, controlling blowdown rate. Without restricting the general rate of industrial sewage control in 5 to 10%, in the pot of water to ensure that qualified (mainly total alkalinity and pH value), the blowdown rate as low as possible, the sewage to adhere to the "ground row, row less, are ranked "the rules. Third, the maintenance of good furnace wall insulation. The heat loss is also a relatively large heat losses, now the manufacturers in the manufacturing and design has been well thought out, so we do not need to change, we just trying to be difficult to maintain. Outer surface temperature generally does not exceed 50 ℃, it will have to find out the reasons such as too high, and remove. Boiler insulation should always be kept dry, for coal, not a long positive run, or easy to damage the coal furnace wall and gate and so on. Fourth, adjust the ratio of fuel and air volume, complete combustion of the fuel as possible. Generally do not have a small amount of wind testing instruments, we can only go by experience adjustment. For oil, the normal combustion flame was yellow-white, non-glare, flame stability, no visible smoke chimney; For coal, the normal combustion flame pale, no visible smoke chimney, basic cinder burn coal particles as even as possible. Fifth, the need for a sound water treatment. Improve water treatment and water quality testing can maximize prevent fouling and correct guidance of the sewage, but it did not do a lot of small, companies usually do not pay attention.
Horizontal hot selling coal steam boiler manufacturer accident treatment method: 1 overpressure accident boiler, boiler overpressure phenomenon of (1) a sharp rise in steam pressure, the pressure exceeds the allowable working pressure gauge pointer over the "red line" safety valve operating pressure is still elevated. (2) the operation of the device is the interlock overpressure protection, should send overpressure alarm signal, stops the air blowing, the wind, coal. (3) steam temperature and steam flow rate reduction increases. 2, to treat boiler overpressure (1) weakened rapidly burning, manually open the valve or bleed valve. (2) increase the water supply, while the lower reinforcing blowdown drum (It should be noted at this time to maintain the normal water level of the boiler), in order to reduce the temperature of the boiler water, thereby reducing the pressure in the boiler drum. (3) as a safety valve malfunction or all of the pressure gauge damage, emergency shutdown, safety valves and pressure gauges are to be repaired after the boost operation. When endanger the safe operation of (4) Boiler excessive pressure, blood pressure should take measures, but too fast buck is strictly prohibited. (5) boiler overpressure eliminate serious, to the shutdown of the boiler internal and external inspection, to eliminate the overpressure caused by deformation, leakage and other safety accessories and maintenance unqualified. 1, the phenomenon of the boiler water (1) below the minimum safe water level line, or no visible water, the water table glass (plate) as a white. (2) as a full-color water level gauge vapor instruction color. Low water level alarm signal (3) water level alarm occurs. (4) low water interlocking means, the water level should be below a prescribed value blower, Fan, grate reduction motor stops running. (5) a sharp rise in the superheater steam temperature, higher than the outlet steam temperature. (6) boiler exhaust gas temperature rises. (7) the water flow is less than the steam flow, causing Should the water tube due to tube cracking or economizer, an opposite phenomenon occurs. (8) When a serious water shortage, can smell the burnt smell. (9) When a serious shortage, the door can be seen from the red-hot waterwall tubes. (10) a serious water shortage, the furnace tube may rupture, then can hear the explosions, smoke and steam from the door, watching spray the fire door.
Dairy production and processing sectors, need a lot of steam on food drying, sterilization, stereotypes, such as processing, hot selling coal steam boiler manufacturer essential. Xinjiang Ake Su Xinnong Dairy Co., Ltd. as a local brand, has a large market users. 2016, Akzo increased demand for dairy production, the original steam boiler company can not meet today's production needs. In the same year, Akzo dairy cooperation with our company, signed a series SZS 6 tons of steam pipe steam boilers, steam support for the dairy industry dairy production Aksu.
The reason gas hot selling coal steam boiler manufacturer flame of abnormal phenomena and processing method. Flameout for the following reasons: 1. Auxiliary trip or power interruption. 2. boiler combustion instability. 3. When the load is too low, due to the sudden drop in load, ignition energy mill will be lost or the combustion is automatically stopped. 4. mutation coal, low volatile or low calorific value. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. 5, the automatic combustion flame detectors or failure resulting in failure to trip mill. 6. The furnace wall or squib serious improper boiler soot-blowing operation, a large amount of steam into the combustion chamber. 7, coal pulverizing system, fuel system failure, resulting in a substantial amount of fuel reduction or interruption. A large amount of water or impurities in the fuel oil gun clogging, or atomized vapor pressure is too low. Second, the phenomenon: 1, furnace pressure was significantly higher, flameless furnace flame monitoring CRT display. Pit of fire no fire. BTG MFT alarm window alarm indicator lights. 2. The unit load is reduced, steam flow drops rapidly, and the temperature of each section of the working medium vapor pressure decrease, a sharp increase in oxygen index. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. 3. Treatment: 1. If you refuse to run MFT protection, emergency stop should be handled according to the situation and stop the supply of fuel. 2.2. Identify the cause of stalling, and try to eliminate it. Conduct a comprehensive inspection of the boiler, and to confirm proper before the device is restarted.
