china high quality coal fired steam boiler china

Boiler structure have? The whole structure, including boiler and boiler auxiliary equipment of two parts. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Boiler body is in two main parts and drum furnace. Also known as the furnace combustion chamber, fuel combustion for space. The solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as fire bed furnace; solid fuel furnace liquid, gas or pulverized, is injected into the combustion chamber is called the fire chamber burner, also known as the furnace fire chamber; air coal particles burn hold it was boiling, and the furnace is inferior fuel suitable for combustion is called fluidized bed furnace, also called fluidized bed furnace; coal particles so that an air flow rotated at high speed, and strongly called fire cylindrical cyclone furnace hearth. The furnace cross-section is generally square or rectangular. Combustion fuel to form a flame in the furnace and high temperature flue gas, so the hearth around the furnace wall is made of refractory material and insulation material. On the inner surface of the wall of the furnace waterwall tubes often laid, it will not burn both protect the furnace wall, and absorb a large amount of radiation heat of the flame and the high temperature flue gas. Furnace design needs to fully consider the characteristics of the fuel used. Each boiler should be fueled with the original design of the fuel. Boilers running economy and reliability are likely to vary greatly reduced when using the characteristics of fuel combustion. And the natural circulation drum is repeatedly forced circulation boiler receiving feedwater to the economizer, the coupling cycle and supplying saturated steam superheater cylindrical vessel. Simplified drum made from high quality steel plate, is one of the heaviest components of the boiler.

6 tons gas china high quality coal fired steam boiler china steam pressure adjusting a boiler operation, must frequently monitor the pressure gauge indicated. To maintain stable steam pressure, boiler pressure must not exceed the design pressure. Second, increasing boiler load: Steam pressure decreased boiler load is increased, if the level is high at this time, the amount of water should be reduced to a water supply or suspend, the amount of coal and increase the air volume. Gradually increase the amount of water at the same time to strengthen the burning, keep the steam pressure and the water level is normal. Third, the boiler load reduction: the vapor pressure rises to reduce boiler load, if the level is high at this time, the amount of coal should be reduced and the air volume, reduced combustion. Then the appropriate water reduction or suspension of water supply to the water vapor pressure and stability in the nominal range. Then press the normal combustion and the amount of feed water 8 to adjust. If the actual water level within the boiler is low, to increase the amount of water should, until the water level returns to normal after the combustion and needs to be adjusted according to the water vapor pressure and load changes.

Reducing the project covers an area large china high quality coal fired steam boiler china and therefore a large high-pressure steam boiler pipe insulation manufacturers buried heating pipe does not require masonry huge trench, just insulation pipe buried underground people, thus greatly reducing the project area, reducing earthwork open dig about 50% or more, reducing the amount of civil masonry and concrete 90%. Gas boiler, pipe insulation and processed in parallel trenching site, linker site only, shorten the construction period can be greater than about 50%, thermokeeping pipe is widely used a liquid, a gas pipeline network, Chemical Engineering Oil pipe insulation, the vapor Hence largest chemical boiler, central heating network, air conditioning and ventilation ducts, municipal engineering. Buried pipe insulation is one kind of good insulation properties, plus safe, reliable, low construction cost of the prefabricated buried pipe insulation. Effective solution incubated urban centralized heating with a high temperature heat input thermokeeping tube, sliding and water lubrication problems exposed tube ends. Buried pipe insulation not only has the traditional trench laying of pipelines and overhead incomparable advanced technology, practical performance, but also has significant social and economic benefits, but also energy-saving heating of effective measures. Prefabricated buried pipe insulation technology using buried heating pipe, marking polyurethane insulation heating pipe technology development has entered a new starting point. Reporters noted that this year again Yajian steel production capacity of about 50 million tons, quit more than 150 million tons of coal production capacity. Even the industry is expected this year to production capacity will be extended to glass, construction accounted for a large reduction in the steam boiler electrolytic aluminum, cement and shipbuilding industries. High pressure steam boiler pipe insulation manufacturers of polyurethane buried insulating pipe evacuated provided.

Battle blue horn sounded, emissions of sulfur, nitrogen and oxygen compounds gradually strict national requirements. To improve the quality of the environment, but also the people a blue sky, in all industries around the environmentally friendly product revolution, Hainan Sinochem Pharmaceutical companies are no exception. By the company investigation and comparison of boiler products, in March 2017 signed a six-ton ​​steam-cleaning integrated condensing gas boiler and steam fast boiler. Tested and post feedback, the boiler equipment installation qualification, operating normally, and successfully passed the inspection by local quality inspection departments of the boiler.
