At present, ZG boiler 's sales network covers more than 80 countries and regions around the world, and ZG boiler 's products are continuously sold overseas.
February 21 this year, the Harbin Municipal People's Government issued the "blue sky Harbin win the Battle of three-year action plan to implement the program" (hereinafter referred to as the "Program"), as follows.
First, strictly control the total coal consumption
The county (city) should shoulder the main responsibility for control of the total coal consumption, according to the focus on the use of coal and clean use of principles, focusing on reduction of non-coal power, propulsion power and other clean energy alternative to coal and oil by 2020, coal accounting for the proportion of energy consumption compared to 2015 decreased by 1.5 percentage points or more.
Second, to strengthen control bulk coal
Full implementation of the "Harbin coal pollution prevention and control regulations" to strengthen quality inspection of coal, coal quality testing organizations standardized sampling, testing system, improve the sampling frequency. Promote clean and efficient coal-fired boiler, wherein an alternative embodiment the biomass must be dedicated biomass boiler, burning raw material briquettes, installation efficient dust removal equipment.
Third, steadily promote clean heating
To promote priority to the development of clean coal utilization and clean energy use, urban urban central heating. Being difficult to cover central heating, gas heating and accelerate the implementation of electrical heating and other heating decentralized cleaning implement "coal to clean energy" units should be synchronized removal of coal-fired boiler, gas boiler for an alternative to the use of low NOx combustion technologies , gas boiler efficiency can not be less than two levels. 2019, clean heating rate of more than 60%; in 2020, clean heating rate should reach 70%.
Fourth, to carry out comprehensive improvement of coal-fired boilers
To develop a comprehensive remediation plan coal-fired boilers, the implementation of cleaner alternative to coal-fired heating boilers. 2019, the urban built-up area, county (city) county towns built-up areas out of 10 tons of steam coal-fired boilers and furnaces and tea, operating the stove, grain storage and drying equipment, coal fired facilities; basic urban built-up area out of 35 tons of steam per hour coal-fired boilers; basically eliminated the urban fringe per hour 10 tons of steam coal-fired boilers; county (city) basically out of the city and county (city) financial support units (including township, village ) per hour, 10 tons of steam coal-fired boilers. By 2020, basically out of 10 tons of steam per hour urban coal-fired boilers; out of the urban built-up area per hour can not discharge standards of 35 tons of steam (or 29MW) coal-fired heating boilers. In the central heating pipe network coverage area, a ban on new or expanded scattered coal-fired boilers.
Fifth, accelerate clean energy development
Orderly development of wind power, wind power construction layout optimization, to carry out decentralized wind power development and construction in the area have developed criteria. Actively promote the construction of biomass power generation. Enhanced geothermal energy exploration, development and utilization of resources to carry out detailed investigation and evaluation of geothermal energy, geothermal energy resources in the region to find out the distribution and exploitation potential. Increase renewable energy consumptive efforts to solve the basic water abandoned, abandoned wind, abandoned light problem. By 2020, the proportion of non-fossil fuels in primary energy consumption of the city's total, compared with 2017 increased by 1 percentage point.
What is a Industry boiler economizer?
Details of the use of steam three phase of fire tube boiler steam boiler equipment should be required to guard against the use of equipment should be increasingly common, although the product performance and stability, reliable operation. But not to say that can be freely manipulated. Now we come to tell you tell us about those issues when using steam boiler equipment should beware of need. First, carefully observed before starting the boiler steam boiler plant boiler observed before the start of the most critical step, we need to observe the site should have a particularly large number, like whether the gas load properly, smoke pipe cover is already open, whether conventional pumps pumping and so on. Only routine to ensure that equipment in order to start the boiler, steam boiler to ensure reliable operation of the various reliable. Secondly, the use of use during the shutdown period shutdown should be the most cautious step, turn a small fire to fire first, then slowly extinguished, burning closed valve. Steam boiler matters which should have reliable use of these, Should you be able to use a lot of attention to these matters, I believe a certain amount of use can be very reliable steam boilers, there are details to avoid improper use form.
Our engineering team designed a threepass fire tube steam boiler with a capacity of 5000 kg of steam per hour and a operating pressure of 10 bar. The Figure below equations shows a standard three pass fire tube steam boiler system used as a template for our engineering teams design.Get A Quote
May 22, 2015 · Reasons of hydrogen fire in a watertube boiler or exhaust gas heat exchanger: The conditions necessary for the initiation of a hydrogen fire fortunately rare are generally accepted to be as follows: 1. Tube metal temperatures of over 705°C. 2. Tubes with some steam content (usually quiescent or of poor circulation).Get A Quote
May 22, 2015 · This white hot fire spread throughout the boiler melting and burning most of the tubes, and also initiated soot fire in the air heater. Water wall and screen tube headers were subsequently found to be blocked solid with plugs of steel which had formed when the molten boiler tubes and run back into their holes.Get A Quote
A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. This is the basic definition of water tube boiler. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are surrounded by water.Get A Quote
A fire-tube boiler differs from a water tube boiler, and is a type of boiler in which hot gases from a fire pass through one or more tubes running through a sealed container of water.The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.Get A Quote
Most of the fire tube boilers now come in a complete package.The main parts of the package are : oil burners. fuel pump. forced draft fan. feed pump. automatic control system. Boiler mountings. The most basic type of a package boiler is single passage three pass design. One such boiler is shown in the figure.Get A Quote
The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank or " haystack " boilers, flued boilers with one or two large flues, fire-tube boilers with many small tubes, and high-pressure water-tube boilers.Get A Quote

Several voltages are encountered in boiler work. The most common are 24, 110 220 single phase; 220 three phase and 440 three phase. In some parts of the country 550 volt, three phase, is being used. 24 volts is normally used for thermostatic an d other open-type controls where human contact is most likely.Get A Quote
Boiler A pressure vessel used to transfer heat energy to a usable medium such as water. Boiler Tubes A passage for products of combustion and hot gases used to heat water in Fire Tube Boilers.

The degree of excitation of the molecules determines the physical state (or phase) of the substance. when steam is taken from a boiler and the boiler pressure drops, some of the water content of the boiler will flash off to supplement the "live" steam produced by the heat from the boiler fuel.Get A Quote
