zhongding oil gas boiler

In early 2013, fast zhongding oil boiler is a food processing company Luohe a 10-ton condensing steam boiler installed integrally cloud service monitoring module, by monitoring the data found in March, the maximum pressure in the boiler set small deviation, the small boiler load adjustment range, and it uses a continuous replenishment way. When such a large load changes, the burner will start and stop frequently, adversely affect the boiler. After the burner system to monitor working properly, timely communication with customers, to help customers put pressure adjusted to the maximum deviation of the normal range. Then return to the display data safe range, the maximum starting frequency is reduced to the burner 4 times / hour from 8 times / hour, reduced by the mean starting frequency of 3.7 times / hr 1 / hr reported in June. At the same time gas consumption decreased by 10% to obtain the customer's trust and recognition.

Such as the use of coal fired zhongding oil boilers, coal heating value 5500Kcal / Kg (in terms of standard coal) around, (coal prices have continued their upward trend in the market price of 460 yuan per ton, and the purchase and sale channel is not smooth, to control the current energy under rotten mining waste and serious situation, the price of coal have continued upward momentum). 10t steam boiler steam coal consumption per ton of 0.2 ton, the price of 92 yuan. The hot gas is 8000kcal / Nm3, the price of natural gas per cubic 2.0 million, according to gas consumption per ton of steam gas consumption 80Nm3, the price of 160 dollars.

Gas zhongding oil boiler room gas leak serious harm to the increasingly tense in recent years as the price of coal and coal supply more of our day to rise, more and more companies turning to heating gas heating from conventional coal-fired heating, gas supply heat its environmental protection, energy conservation in the country has been more widely used, especially gas central heating boiler room the most popular. So gas boiler room safety management has also become an important issue in the heating industry attention. In recent years, Nansen boiler room with heating company EMS / OSH / HSE management system as the carrier continued analysis of hazards and risks boiler room gas leak, the development of effective preventive measures, the use of a number of advanced new technologies at home and abroad, new technology and new equipment to ensure the safe and stable operation of the boiler room. The main component of natural gas we use are: methane content 98, the content of 0.3 propane, butane content of 0.3, 1 and the nitrogen content of other substances, high calorific value 9650 kcal / standard side, the low calorific value 8740 kcal / standard side, explosion limit: 5-15. We call regional gas may leak means natural gas pipeline, a valve table, fitting between the regulator from the station to the boiler (including boilers) and the like. Wherein the regulator station for the fan to between buried pipeline between the boiler to fan out to the overhead line. Gas explosion in an instant, (the number of thousandths of a second) the production of high-temperature (up to 3000 deg.] C), high-pressure combustion process, explosion velocity of up to 300m / s, resulting in a great destructive power. If a natural gas leak encountered fire, static electricity, lightning or improper operation such as an explosion, a fire in a confined space will make people hypoxia, asphyxia and even death, to production safety and the state and the people incalculable loss of life and property .

Four combustion modes of zhongding oil boilerBoiler as an energy conversion equipment, plays a very important role in industrial production, can be said to be the core main force of production enterprises. I know the boiler, but it is estimated that most people do not know much about the combustion mode of the boiler. Today, our Fangkuai Boiler will take you to understand the four combustion modes of the boiler. It can be divided into suspended combustion, boiling combustion, layered combustion and gasification combustion. The following is one by one. First, suspension combustion, also known as fire chamber combustion, is a combustion mode in which fuel is injected into the furnace with air in the form of fog, powder or gas. Suspension combustion ignition is rapid, combustion heat The efficiency is high. It is easy to realize automatic operation. The adaptability to load variation is strong. And the adaptability to the fuel is also strong. However, this combustion mode requires a high level of operation, and should not run intermittently. Secondly, boiling combustion is a kind of fluidized boiling combustion of fuel in fluidized bed under the action of appropriate velocity of air. Boiling combustion is suitable for all kinds of coal, especially inferior coal, such as coal gangue. Stone coal, and so on, this combustion mode on the size of coal particles also have certain requirements. The coal mass must be processed and broken into particles with an average diameter less than 10mm during combustion. Delivered by coal-feeding equipment Enter the furnace. Third, layered combustion, also known as fire bed combustion, is a way of burning fuel in a certain thickness on the grate. This combustion mode is only suitable for solid fuels. However, there are certain requirements for particle size (6~50mm). Layered combustion can basically adapt to solid fuel. As long as the mixture of air and fuel layer is good, and there is a certain combustion temperature, the ideal combustion can be achieved. If the air and fuel layer do not mix well, or the local air supply is insufficient, the combustion will be incomplete and the combustion efficiency will be low. This type of combustion is generally used in chain furnaces. IV. Gasification combustion Gasification combustion mainly refers to gasification and direct combustion of coal put into furnace, and this combustion mode is not suitable for coal with low ash content. High-temperature gasification and staged combustion is different from ordinary gasification combustion. Its utilization principle is as follows: under the condition of oxygen, the fuel surface is heated with high-temperature heat source above 800 ℃, so that the fuel can be rapidly pyrolysis and gasification combustion from outside to inside. Part of the high temperature produced by combustion is then gasified at high temperature, and part of the fuel is discharged for work, thus forming a continuous high temperature gasification combustion reaction.
