Industrial Vacuum Boiler manfuacturer in China

Le 18 septembre 2015, 10:45 dans Humeurs 0

ZG is one of industrial vacuum boiler supplier in China with 70 years boiler history since the year of 1945 with rich vacuum boiler experience. ZG vacuum boiler has below advantages:

1.High safety and reliability: Vacuum operation unit, hot coal in vacuum state, there is no danger of expansion and explosion. Having constant thermal coal water in the furnace makes no danger of ingredient. Multiple automatic protection devices have much higher safety than other boilers.
2.No corrosion and scaling, long service time: Using stainless steel thermal ex-changer makes thermal coal operate in a closed state. No corrosion and scaling make its service life twice longer than ordinary boiler, which can be used for 20 years.
3.Variety model, one model many uses: There many types for customers to choose such as vertical type, horizontal type, oil-fired type, gas-fired type, water pipe, smoke pipe,
4.Small size and easy installation: Modular design, high performance heat transfer components, small size make it easy to transport. In a small space, multiple units can be used parallel.
5.Functions of environmental protection: Unusual environmental functions: Using high performance burner, designing back flame structure makes full fuel combustion. Every environmental protection indicators meet the state' emissions standards of tourism area.
6.Exempt from the complicated approval procedures: Units operating in the vacuum state streamline the approval of the pressure vessel, such as the annual evaluation procedures.
7.Intelligent control: Touch-screen display, virtual buttons, words and graphics display the situation of systems; The online guides, fault diagnosis, automatic operation and a manual operation also can be used .

With more than 7 decades experience, ZG has built one set of  8ton vacuum hot water for a civil heating in China. Except, we also delivery industrial vacuum boiler to worldwide, like India, Pakistan, Bangladesh, Vietnam, Indonesia, Philippines, South Africa, South America etc country and areas.

Energy conservation of industrial steam boiler

Le 17 septembre 2015, 10:47 dans Humeurs 0

With the increasing costs of resource and awareness of environmental protection,reducing the energy consumption and the heat loss become an imperative matter of the industrial steam boilers.the experts from China-steam boiler-manufacturer ZG give us the following suggestions to achieve that.

optimizing the heating way of industrial steam boiler

Combustion modes of industrial steam boiler are layer combustion,chamber combustion and boiling combustion,because the space design of industrial steam boiler is not perfect,in most conditions,the fuel can not be burned sufficiently,so,changing the type of steam boiler and improving the combustion condition are the basis of the normal operation of industrial steam boilers.

Increasing the combustion efficiency

For the layer combustion of large industrial steam boiler,according to the characters of staged combustion and different consumption of coal,we can take segmented air supply measures,which is adding a secondary air supply with maintaining the temperature of furnace at the same time,to enhance the thermal efficiency by sufficient combustion of coal dust in fuel gas.

Ladder application of thermal energy

The rise of combustion efficiency becomes more difficult because of the maturity of combustion level,therefore,enhancing the utilization efficiency Of thermal energy in the heat transfer process,realizing the ladder application by considering the using and recovery of high grate energy first,then using the low grate energy,will have goos economic benefit.
Waste heat recovery

A lot of high temperature flue gas exists in the operation of industrial steam boiler,if it can be recovered to use again, we can achieve the energy conservation in some degree.

There are so many ways to reach our aim of energy conservation,to adapt to the development of our society,we must explore them continually.

differences between water tube boiler and fire tube boiler

Le 16 septembre 2015, 11:05 dans Humeurs 0

The definition of the water tube and fire tube is decided by the medium of the pipe. The water pipe means that the pipe is used to transmit water which is heated through the outside smoke convection while the fire pipe is used to sent smoke. The structure o f the fire pipeline is simple and it has large steam volume and good adaptability for load. its required water quality is lower than that of water pipe boiler. Therefore, the fire pipe boiler is widely used in small-sized enterprise and life-oriented fields. However, the heating area of the water pipe is easily to distribute and has good transmission efficiency. This kind of structure can be used in large volume and high parametric. Furthermore, it has more strict requirements of the water quality and operation skills. Other specific differences:

1.the pressure of the water pipe coal fired boiler is more widely adaptive and it can satisfy the highest pressure requirements of 2.5Mpa while the fire pipe boiler is limited by the thickness of the material and pressure,it can only be used in the condition of under 2.5 mpa.

2.Fire tube boiler is shell boiler. It is difficult for the manufacturer to make large-sized one because of the limited equipment. Its largest largest capacity is not more than 35ton. Otherwise, the water tube boiler have no limit on the size.

3.The fire tube boiler is very compact, with the same capacity, its weight of the shell and the equipment is lower than that of water tube boiler. But, the water tube need more space to distribute the superheater, so the water tube need a large boiler room.
