Gas-fired vertical oil steam boiler is an advantage on the device using an environmentally friendly energy-saving: With the designers re-design of mechanical innovation, simple and easy to operate equipment, gas steam boiler is not only relatively simple, and better ensure the safe operation of ; saving advantages: high-temperature low-pressure gas steam boiler with a characteristic greatly reduces the stress levels of heating equipment, less direct advantage is the reduction in equipment investment. Electric heating boiler and the boiler is mainly composed of electric control box and control system. Its characteristics are environmentally friendly, clean, no pollution, no noise, automatic, with limited energy and reduce prices significantly, as a new boiler electric heating boiler equipment increasingly being recognized. Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage. 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. It was also said that the proportion of contact with air, just the right amount of fuel and the amount of combustion air composition in order to achieve combustion efficiency, but also reduce gas emissions and achieve energy-saving dual, very convenient. Gas steam boiler may be configured according to the actual amount of steam required, thus reducing waste of energy. The higher the degree of matching the actual demand and supply theory, better energy-saving effect. Continuous sewage heat can be utilized by a heat exchanger, thereby increasing the water temperature deoxygenated water. Gas-fired steam boilers and other machinery and equipment, more in line with current environmental requirements, so it has been widely used.

In most people's concept, the boiler is "silly, big, stupid, thick" representative. But in the fast boiler, but it will completely subvert the concept. When you first meet with the parties boiler fast, never thought the equipment was actually in front of a boiler. They look neat and clean, the overall design is very smooth, the boiler is also not "clumsy" shadow. Mr. Lu Haiqing Group Chairman, says: "Right now, we have four types of enterprises, more than 200 kinds boiler models, innovation and creativity we have tasted the sweetness." The face of fierce market competition, the fast side of the family must go deeply understand the creation of independent innovation road to seek greater development. We respond positively to national development strategies, investment in research on clean and environmentally friendly gas boiler, set up research cooperation with Tsinghua University base, development pattern of innovation and development of new products.

ZG production of DHL package vertical oil steam boiler is committed to energy conservation and environmental protection, is widely used. It is through the efficient combustion of some biomass fuels, rice husk, sawdust, agricultural waste, to ensure the efficient, clean, safe and stable operation of the boiler. The series of boilers using a new furnace structure, to avoid the direct heating caused by the bottom of the raised, also designed a two-wing gas pipeline structure, to avoid the flue crack.

2. Oxygen corrosion

For the biomass fuel boiler pressure parts,the water side is mainly electro chemical corrosion,the fire side (or flue gas side) is mainly chemical corrosion.The oxygen corrosion belongs to electrochemical corrosion, it is mainly caused by the dissolved oxygen in water.At room temperature,the dissolved oxygen concentration is about 9.1mg / L,according to the GB1576-2001 “industrial boiler water quality” requirement ,the rated steam pressure should not be more than 1.0MPa,the dissolved oxygen concentration should not be more than 0.1mg / L,otherwise,it is likely to lead to metal corrosion.
