boiler for paper making industry

In October 2016, my company and the China Dunhuang International Hotel signed a ZWNSL2.1-1.0 / W-Y.Q vacuum condensing gas hot water boiler for paper making industry to provide heating and hot water for the hotel. The boiler implementing the response to the national policy of environmental protection requirements and local environmental protection departments on a series of low nitrogen emission standard boiler requirements, in terms of design, manufacture, installation and other sectors have strict checks to ensure that the boiler safe and stable operation.

Why do gas-fired steam boiler for paper making industrys require high water quality?

Many boiler users know that when buying a boiler, the boiler manufacturer's technicians will repeatedly explain the requirements for the boiler water quality. This is because the boiler water quality is a prerequisite for the normal operation of the steam boiler. Correct and reasonable water treatment can be used. Avoid the scaling and corrosion of gas boilers, extend the service life of boilers, reduce energy consumption, and improve the economic benefits of enterprises. Today we will talk about the impact of water quality on natural gas steam boilers.

Third, environmental protection, not a traditional boiler for paper making industry combustion noise-free module boiler system wind equipment, the human ear can hardly be heard boiler operation. Meanwhile, the boiler burner block often used aluminized steel, sophisticated technology, to ensure efficient combustion, the combustion rate of 98%, and substantially no environmental pollution. Product safety: safe and reliable gas boiler module, open the module installed boiler pressure system during operation always in addition to normal pressure, but also with multiple perfect safety functions: flameout protection; anti-dry protection; frost protection ; low protection level; auto exhaust protection; preventing overheating protection leakage protection; built-in installation: water system is always closed during operation under pressure 0.05 ~ 0.3Mpa, the system having a security function in addition to mounting the outer open also has a protective function: expansion pressure protection system; low-pressure water protection system, high-pressure safety relief protection. Gas boiler classification module start, significant energy saving. By fractional gas boiler module system start function, the system in accordance with the size of thermal load, automatic adjustment module stops, when each module reaches full capacity and then start another module, so as to ensure the system is always match the actual heat output heat load demand, ensure that each boiler was operated at peak efficiency, maximize operational heat efficiency of the whole system, completely solve the traditional operation of large boiler of energy wasted. Meanwhile, the control system automatically balance the operating time for each module, extending the life of the overall system. Smart central controller with an indoor temperature sensor and a water temperature sensor, real-time acquisition and the indoor ambient temperature signal automatically calculate the optimum heating water temperature, and controlling the number of modules in operation, while maintaining room temperature stability, saves fuel, significantly reduced Operating costs. Commercial gas boilers climate compensation modules, outside temperature in different months in low-cost gas boiler heating season is different, the same day the outdoor temperature is different at different times of the heat demand of the building will vary widely.

What is a modern large-scale boiler for paper making industrys, industrial boilers and what is the difference between: industrial boilers and power plant boiler structures have their own characteristics. Higher boiler power plant parameters, the structure is more complicated, suspension structure, membrane wall rarely used in industrial boilers, utility boilers, but in a wide range of applications. With the improvement of the working pressure, the vaporization heat boiler to reduce the proportion, increase heat absorption overheating. Utility boilers have been arranged in the furnace wall to meet the requirements of the evaporator heating surface, so that no longer as industrial boilers, evaporation convection bank is often necessary, even more superheater is disposed, and even part of the superheated heating surfaces are arranged in the furnace . Large capacity and high parameter boiler reheater is also arranged.
