Multi-fuel CFB boilers typically burn a mixture of waste or alternate fuels along with natural gas, fuel oil,or pulverized coal.This provides an opportunity to produce steam at lower cost than a basic fossil fuel fired unit, but it also makes operations more challenging.Waste and alternate fuels vary in Btu content per volume and their supply is often not consistent. This significantly affects combustion stability and the ability to reliably meet load. More expensive fossil fuels must be used when waste and alternate fuel is not available or to make up for low Btu. Managing this without excessive cost is difficult.In addition, operating within emissions constraints may be a problem with multiple fuel streams in the mix.
Gas gas-fired boiler for school and hotel 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 .
Besides the biomass fuel boiler, gas fired steam boiler or oil fuel steam boiler can also be used in rice factory. With packaged style, the boiler is easy to transport and install. It can get the capacity of 6~35t/h under pressure1~2.5Mpa, temperature 193~300℃. The boiler can burn natural gas, heavy oil, LPG, coke oven gas,etc. It has also many advantages such as large combustion chamber, strong load adaptability, safe and reliable operation, long service life, environmental friendly and so on.
It is reported that fast gas-fired boiler for school and hotel opportunity to help APEC summit, with more than Institute, universities collaborate to jointly develop the latest ultra-low nitrogen oxide emissions control technology, nitrogen oxide emissions will be maintained at 33 mg / m within the scope of the emissions has exceeded European standards in the future, this technology will better serve the Beijing as well as the national gas boiler renovation project. "Our vision is to: continue to meet the energy needs of user convenience and energy saving, the fast boiler build the first brand of Chinese clean boiler future we will continue in different areas of ultra-low nitrogen, ultra-low dust, low noise, etc. continue to explore. in order to achieve greater results. "the technician said in conclusion.
