Because a certain amount of air is usually dissolved in water, with the increase of temperature, the solubility of air decreases, and the gas is gradually separates from the water in the process of water circulation, and gradually gathers together to form large bubbles and even gas columns. Gas is often produced due to the water supplement, so the boiler exhaust valve must be used to avoid damage to the system.
The type and parameters of coal-fired boilers are the direct factors affecting the cost of a small coal-fired boiler. For example, rated capacity, rated steam pressure, rated steam temperature, feed water temperature, etc. With different parameters, the more requirements, the higher the price.
New energy boiler fuel is a new clean and environmentally friendly fuel product. The fuel of new energy boiler is clean, sanitary, green and environmentally-friendly. No "three wastes" such as waste gas, wastewater and waste residue are discharged in the production process. It has high oxygen content, full incineration, no black smoke, no carbon deposit, no boiler black bottom, no residual liquid or residue. The waste gas from incineration is more than 80% lower than that of LPG.
As an important heat energy supply equipment, industrial boiler is widely used in food, electronics, paper making, building materials, textiles and chemical industries. According to the medium, industrial boilers can be divided into steam boilers, hot water boilers and thermal oil heaters. In order to solve the problem "How many tons are the rated thermal power of 42 MW of industrial boiler?" First of all, we need to know the basic knowledge of rated thermal power and unit ton.
Boiler water circulation refers to the circulating flow of water and steam-water mixture on the evaporating heating surface of boiler. What is the working principle of the latest water circulation system of boiler?
Deaerator is one of the key equipment in boiler and heating system. With the popularization and development of demineralized water treatment technology, deoxidization of boilers and heating systems becomes more and more important.
Hot-water boiler is a kind of thermal equipment that uses the heat energy released by fuel combustion or other heat energy (such as electric energy, solar energy, etc.) to heat water to the rated temperature. According to different fuels, hot water boilers can be divided into gas-fired hot water boilers, oil-fired hot water boilers, biomass-fired hot water boilers, and coal-fired hot water boilers. How to choose hot water boiler? We will focus on the heating, pressure and thermal efficiency of hot water boiler.
The rated output of boiler refers to the maximum sustained output of industrial boiler under rated parameters (pressure and temperature) and certain efficiency. For steam boilers, the rated output is also called rated capacity, and the unit is t/h (tons/hour); For a hot water boiler, the rated output of the boiler is also called the rated thermal output, and its unit is MW.
