20T H Fuel System Boiler


20T H Fuel System Boiler

Subsequently, the delegation visited the company's 20t h fuel system boiler cleaning laboratory, technicians demonstrated to the delegation of the company's latest product boiler operation, and use of DCS control system in the laboratory trace data. Mr. Liu to our boiler products to achieve nitrogen oxide (referred to as NOx) emissions below 18 mg or less, is widely used in Beijing APEC venue, the Central Authority and other countries prefix institutions and other international occasions expressed a high degree of praise and encourage.

What are the main hazards and countermeasures gas steam 20t h fuel system boiler there? Although gas steam boiler is essential for the production of many enterprises power supply equipment, but in practical applications of gas steam boiler danger also exists, therefore, fireman operation of the boiler must have professional credentials and job experience. Following on from a wide variety of gas steam boiler manufacturer to introduce measures to deal with and what are the main danger there. 1, when the boiler water to dry gas steam boiler when the water level is below the limit, the exhaust gas temperature rises and a boiler top will produce burning smell, we have been able to see the red-hot waterwall tubes from the door, tube also serious distortion even burst pipes, and can hear the explosions, smoke and steam discharged from the door to see the fire door. After this occurs, the supply of fuel should be stopped and a blower, extinguishing water into the furnace, if necessary, but be careful not to water boiler in such case. 2, if the boiler overpressure gas steam boiler steam pressure rises sharply and exceeds the allowable operating pressure, the pressure gauge pointer over the "red line", the safety valve, when the pressure is still elevated on the issue of overpressure alarm, steam but with an increasing temperature will reduce the flow of steam. If this dangerous situation, should weaken rapidly burning, gas steam boiler manually open the safety valve or vent valve to increase water supply, sewage increase, reducing the pot of water to reduce the temperature of the boiler drum pressure. 3, water wall boiler tube can hear a distinct blast tube pops sound or jet, pressurized combustion furnace by the combustion pressure becomes far, and has a vapor from the flue gas and can not see where fire doors and close the door, etc. ejection. If the furnace gas steam boiler tube rupture is not serious and can maintain the level, not to expand the accident, it can reduce short-term load operation, if it is serious burst pipe and the water level can not be sustained it must be an emergency shutdown. Hot gas steam boiler manufacturers to introduce the main boiler of several dangerous situations and corresponding measures. If the boiler water shortage occurs, the overpressure and burst pipes are extremely dangerous if not handled properly it will lead to serious accidents, so enterprises must be very careful when using gas steam boiler, the dangers to a minimum.

Hazard scale steam 20t h fuel system boiler steam boiler scale produced when using what harm it? Xiao Bian told you about hazards under the steam boiler scale today, hope can help to you. 1, waste of fuel, because the thermal conductivity decrease the thermal efficiency of the steam boiler scale ten times larger than the thermal conductivity of steel to the fractional number of times. Thus when the steam boiler scale junction, heat transfer performance of the steam boiler heating surface is deteriorated, fuel combustion heat is not released efficiently transferred to the boiler water, a large amount of heat is taken away by the flue gas, resulting in increased exhaust gas temperature, increase heat loss, reduce the thermal efficiency of the furnace. In this case, in order to ensure the parameters of steam boilers, adding more fuel would have to increase the temperature of the furnace and flue gas temperature, thus resulting in wasted fuel. It was estimated that the furnace has a heating surface junction 1mm thick scale, waste of fuel from about 3% to 5%. 2, the impact the safe operation of the steam boiler scale often generate high heat load heating surface. Scale due to the poor thermal conductivity, leading to greatly increased local temperature of the metal wall. When the temperature exceeds the allowable metal temperature can withstand, the metal creep due to overheating, decrease in strength, the working pressure in the boiler, a metal bulge will occur, and cracking of perforation, affect the safe operation. 3, the decrease of the steam boiler output scaling boiler, heat deterioration due to evaporation or to the rated nominal heat production, it is necessary to consume fuel. However, with the increase in scale thickness, and the area of ​​the grate furnace volume is constant, the fuel consumption is limited, the output of the furnace will be reduced. 4, fouling will reduce the life of the scale steam boiler heating surface shall be completely removed in order to ensure its safe operation. Whether manual, mechanical, or the use of cleaning chemicals will affect its service life. These are the steam boiler scale harm, in order to prevent the generation of scale, we can reduce the water flow rate, regular cleaning and other measures to reduce the harm of scale.

At present, in order to save more expenses, many enterprises often adopt unscientific methods to treat 20t h fuel system boiler water, and all kinds of tools and instruments used in the process of boiler water treatment do not meet the relevant regulations. For example, "three no" electronic anti-scale instruments and anti-scale agents and so on.
