About methanol boiler fuel: methanol

A boiler consists of two parts: a pot and an oven. The original meaning of a pot refers to a container of water heated over a fire, and a furnace refers to a place where fuel is burned. The hot water or steam generated in the boiler can directly provide the heat energy needed for production and life, or it can be converted into mechanical energy through a steam device, or the mechanical energy can be converted into electrical energy via a generator. Boilers that provide hot water are called hot water boilers. They are mainly used in everyday life and also have a small number of applications in industrial production. The boiler that generates steam is called a steam boiler, also called a steam generator, often called a boiler. It constitutes an important element of the steam energy production device and is principalipally used in thermal power plants, ships, locomotives and industries and mines. businesses. Boilers are subjected to high temperatures and pressures, so safety issues are very important. Boiler capacity can be expressed as the rated evaporation capacity or the maximum continuous evaporation capacity. Rated evaporation capacity is the amount of steam produced continuously per unit time under a specified outlet pressure, temperature and efficiency. Maximum continuous evaporation capacity is the maximum amount of vapor that can be produced continuously per unit time under the specified outlet pressure and temperature. Steam parameters include boiler steam pressure and temperature, which generally refers to the pressure and temperature of the superheated steam leaving the superheater and reheater. If there is nosuperheater nor reheater, they refer to the pressure and temperature of the saturated steam. boiler outlet. Feed water temperature refers to the economizer inlet water temperature. If there is no economizer, it refers to the drum inlet water temperature. Boilers can be classified in different ways. Boilers can be divided into industrial boilers, power plant boilers, marine boilers and locomotive boilers according to their uses according to the boiler outlet pressure, they can be divided into low pressure, medium pressure, high pressure, ultra high pressure, subcritical pressure. , supercritical pressure and other boilers; according to the circulation method, they can be divided into natural circulation boilers and auxiliary circulation boilers (that is, forced circulation boilers), pa boilers.single ssage and compound circulation boilers according to the combustion methods, boilers are divided into chamber furnaces, layer furnaces and; boiling furnaces. Regarding the water vapor system, after the feed water has been heated to a certain temperature in the heater, it enters the economizer through the water supply pipe. After further heating, it is sent to the drum, mixes with the water in the pot and. then flows to the water wall inlet collector. Water in the water-cooled wall tube absorbs radiant heat from the furnace to form a steam-water mixture that reaches the drum through the riser tube. Water and steam are separated by the steam-water separation device. The separated saturated steam flows from the upper part of the drum to the superheater, continues to absorb heat and becomes superheated steam at 450°C, then is sent to the steam turbine. In thisRegarding combustion and combustion air systems, the fan sends the air into the air preheater to heat it to a certain temperature. The main components of the boiler, such as furnace, drum, burner, water wall superheater, economizer, air preheater, frame and furnace wall, constitute the essential part of the boiler. heat production and are called boiler bodies. The two most important parts of the boiler body are the furnace and the drum. The furnace, also called the combustion chamber, is the fuel combustion space. The furnace in which the solid fuel is placed on the grate and burned on the fire bed is called layered combustion furnace, also known as fire bed furnace; the furnace in which liquid, gaseous or powdered solid fuel is sprayed into the fire chamber for combustion is called chamber burner, also known as no.m combustion chamber furnace; the air lifts the coal particles and burns them to the boiling state, and is suitable for burning low-grade fuels.The furnace is called boiling furnace, also known as fluidized bed furnace; The cylindrical furnace which uses air flow to make the coal particles rotate at high speed and burn intensely is called cyclone furnace. The cross section of the oven is generally square or rectangular. The fuel burns in the furnace to form high temperature flames and combustion gases, so the furnace walls around the furnace are made of high temperature resistant materials and insulation materials. Water-cooled wall tubes are often laid on the inner surface of the furnace wall, which not only protects the furnace wall from burnout, but also absorbs a large amount of radiant heat from the flame andhigh temperature combustion gas. The design of the furnace must fully take into account the characteristics of the fuel used. 1. Boilers can be classified based on their purpose. The boilers can be used as thermal boilers and heating boilers. Electric boilers include power plant boilers, ship boilers and locomotive boilers, etc., which are used for electricity generation, ship power and locomotive power. Heating boilers include steam boilers, hot water boilers, heat pipe boilers, hot blast furnaces and heat transfer heating furnaces, etc., and obtain steam and hot water accordingly. Hot air and heat transfer, etc. 2. Classification according to the structure of the boiler body. According to the structure of the boiler, it is mainly divided into boilersfire tubes and water tube boilers. Fire tube boilers include vertical boilers and horizontal boilers, and water tube boilers include horizontal water tube boilers and vertical water tube boilers. 3. Classification according to the type of fuel used in boilers. Depending on the type of fuel used in the boilers, the categories are coal-fired boilers, oil-fired boilers, and gas-fired boilers, as well as coal upgrade technology. fire boilers, substitute products for oil and gas furnaces --- pulverized coal boilers, dual-purpose gas boilers, etc. Coal-fired boilers can be divided into layer boilers, chamber boilers and boiling boilers according to their combustion methods. 4. According to the classification of boiler capacity, those with an evaporation capacity less than 20 t/h are calledsmall boilers, those having an evaporation capacity above 75 t/h are called large boilers and those having an evaporation capacity between the two are called. called medium-sized boilers. 5. According to the classification of boiler pressure, boilers below 2.5 MPa are called low pressure boilers, those above 6.0 MPa are called high pressure boilers, and those with pressure between the two are called medium pressure boilers. There are also ultra high pressure boilers, subcritical boilers and supercritical boilers. 6. Classification according to the boiler water circulation form. Boiler water circulation forms can be divided into natural circulation boilers and forced circulation boilers (including once-through boilers). 7. According to the shape of the device, it can be divided into quick installation boilers,assembled boilers and bulk boilers. There are also wall-mounted boilers, vacuum boilers and modular boilers.
