condensing gas boiler systems

What is the difference between a gas-fired condensing boiler systems and a coal-fired boiler?

Both gas and coal can be used as fuel for boilers, but different types of boilers are named according to the types of fuels used, so there are gas boilers and gas boilers. So what is the difference between a coal-fired boiler and a gas-fired boiler, apart from the fuel used in combustion?

1. The fuel used by different coal-fired boilers to exhaust smoke is coal. When coal burns, it will cause serious pollution to the environment by producing larger smoke and dust. However, high-stability gas-fired boilers do not emit black smoke after combustion. Because gas can basically be completely burned, smoke-emitting black poison can reach zero level, the content of SO2 in it is very small, so there is no pollution to the environment.

2, heat loss is different in order for coal-fired boilers to maintain adequate combustion intensity, the use of human or other equipment to constantly add coal to the furnace, when the need for intermittent operation, It takes a long time to raise the temperature in the furnace when starting again, so it will produce great heat loss when pressing fire, and the gas-fired boiler is very convenient to start and stop, and can heat up rapidly during intermittent operation, so as to reduce the heat loss in this process.

3, the different ways of treatment after combustion will produce a large amount of ash after burning in the boiler. In order to maintain the health of the environment, the ash will be transported to the professional slag removal yard for treatment, but gas is used in the gas-fired boiler. There will be no residue after combustion, so there is no need to deal with it. It not only avoids the pollution to the environment, but also reduces the labor intensity of enterprises and the storage and transportation of urban ash.

Steam condensing boiler systems is one of the indispensable devices in the pharmaceutical industry, decoction of Chinese medicine, medicine drying, sterilization, cooking gum, drying, tabletting and capsule production processes, a large amount of steam will be used. West Libang Pharmaceutical Co., Ltd. is a pharmaceutical research and development, production and sales of high-tech enterprises, the existing anesthesia, cardiovascular, child immunization, pharmaceutical raw materials, pharmaceutical excipients, nutrition series of six automated production lines. With the increasing strength of China's environmental protection, some high-pollution devices are making the transition to clean environmental protection. Libang Pharmaceutical respond positively to national coal to gas policy, decided to change the existing coal-fired boilers to clean better gas steam boiler. Fast boiler with strong comprehensive strength in the field of clean energy, Libang Pharmaceutical after conducting comprehensive consideration, determined to cooperate with the fast boiler. The two sides further understanding, party fast technical engineers according to production needs state power, and soon its development of specific solutions for its recommendation of a 6 tons of steam condensing gas steam boiler (WNS6-1.25-Y.Q).

After gas-fired condensing boiler systemss for low-nitrogen transformation impact: environmental protection efforts continue to increase, the provinces and cities have introduced various environmental policies. Air pollutant emissions is one of the main issues of governance and environmental protection sectors. For gas-fired boilers for low-nitrogen transformation has also become popular, such as Beijing, Tianjin, Zhengzhou, Xi'an and other places are carrying out renovation work and out of the boiler. Natural gas as a clean energy, can be reduced nearly 100% of the sulfur dioxide and dust emissions, 60% of carbon dioxide emissions and 50% of nitrogen oxide emissions, and help to reduce acid rain, global warming alleviate, reduce proportion of the amount of coal energy important energy; corresponding gas boiler has gradually been used and popular. But not as long as the use of gas-fired boiler can, according to China's introduction of the latest air pollutant emission standards, Beijing and Tianjin, the Yangtze River Delta and other regions, and Zhengzhou, Xi'an and other cities ever to perform the most stringent air pollutant emission standards --30 mg / cubic meter. Many enterprises due to gas-fired boiler installation time relatively early, current nitrogen oxide emissions higher than this standard, however, when the burner exhaust emissions can not meet the standards formulated by the state, need to deal with the transformation of low nitrogen may continue to be put into use .

Biomass fired condensing boiler systems fuel characteristics

Biomass fuel has the following main characteristics compared to coal:

1. Low sulfur content. Biomass fuels are mostly less than 0.2% sulphur, and there is no need to install a gas desulfurization device when burning, which reduces costs and is environmentally friendly.

2. Most of the carbon in the biomass fuel combines with hydrogen to form a low-molecular hydrocarbon. After a certain temperature, it thermally decomposes and folds out the volatiles. Therefore, biomass fuel is easily ignited,

3. The density is small. The density of biomass fuel is obviously lower than that of coal, and the texture is relatively loose, especially crop straw, which is bulky.

4. Less carbon. The highest carbon content in biomass fuels is only about 50%, which is equivalent to the carbon content of lignite with less generation.

5. Straw biomass contains a large amount of alkali metal elements (mainly potassium and sodium). In the combustion process of biomass, the main performance is that the adhesion of ash is strong, and slagging and clogging are likely to occur in the furnace. Ash accumulates on the heated surface of the tail.
