The key to avoiding the excess air in the furnace is the proper air distribution and the appropriate monitoring and control means. The monitoring method has a method for measuring the content of CO2 or O2, and the oxygen content of the gas economical industrial water tube boiler is usually determined. This is because the gas boiler is burned with a slight positive pressure, and the sealing problem is easily solved. The measurement of the oxygen content accurately reflects the excess air coefficient value. Nowadays, the oxygen content measurement technology generally uses a zirconia constant temperature oxygen analyzer to continuously measure the oxygen content of the flue gas. According to the oxygen content of the flue gas as a reference, the air-fuel ratio is properly adjusted to perform low-oxygen combustion.

A scale-up of the technology to 100 MW is investigated in terms of mass and heat balances,flows,solids inventories,economical industrial water tube boiler dimensions and the major differences between a full-scale Circulating Fluidized Bed boiler.Furthermore, the additional cost of 100MW CFB power plant boiler relative to CFB technology is analysed.The largest cost is made up of compression of CO2,which is common to all capture technologies. Although the need for oxygen to manage incomplete conversion is estimated to be only a tenth of that of oxy-fuel combustion,oxygen production is nonetheless the second largest cost.Other significant costs include oxygen-carrier material, increased boiler cost and steam for fluidization of the fuel reactor.

The second reason is that it can reduce the frequency of replacing heating equipment in modern people. At present, the raw materials used in common economical industrial water tube boiler products in the market are mostly copper, which is easy to be corroded and replaced by a series of faults after long-term use. The condensing boiler is made of stainless steel, and even in the process of operation, the contact with water vapor will not affect the quality of the boiler, so that the frequency of replacing heating equipment can be controlled inconspicuously.

In the low profit era of Chinese paper packaging industry, entrepreneurs have been turning their attention to internal management, increase business efficiency by saving energy. At present, the paper packaging industry equipment many of them appear old and comes with a variety of issues, in particular energy use seriously inadequate problem is solved and bear the brunt of reform issues. So we must make an effort in the use of energy, use energy-saving equipment for the industry, in order to solve the problem fundamentally.
