What does the specification of the steam boiler 0 5t h indicate

Indicates that the rated evaporation capacity is.

That is, the boiler produces steam per hour.

Indicates that the rated evaporation capacity of the steam boiler is tons per hour.

Rated evaporation capacity: ton h

The amount of steam produced per unit time of continuous operation of a boiler is called the evaporation capacity of the boiler.

Evaporation is also known as "output" or "capacity". Terms such as boiler rating (boiler rated load) (BRT) and boiler maximum continuous rating (BMCR) are often used in the power generation industry. The so-called boiler rated output is the boiler output heat power of the boiler under the conditions of rated steam parameters and feed water temperature, which matches the rated output (TRL) of the turbine-generator set, MW.

It is customary to express the main steam flow rate (t h) under this working condition, so it is also called the rated evaporation capacity of the boiler. The main steam flow in the TRL case is the same as the main steam flow in the Turbine-Generator Maximum Continuous Power (TMCR) case. The BRL operating condition should be in the load zone with the highest thermal efficiency of the boiler, usually the thermal efficiency of the boiler [ Guaranteed Operating Condition.

The maximum continuous output of the boiler is the maximum continuous output heat power specified when the design flow conditions of the boiler and the steam turbine unit are matched, mw; It is also customary to express the main steam flow rate (t h) under this condition. BMCR is generally the guaranteed value of boiler design. The design pressure and water circulation reliability of the boiler meet the requirements of this working condition, and the furnace should have no serious or high slag formation tendency under this working condition, and the auxiliary parameters should meet the needs of this working condition.

The thermal efficiency of the boiler in the BMCR condition is allowed to be lower than that in the BRL condition. Practice has proved that if the evaporation of the coal-fired steam boiler [ url[ b is reduced to 60% of the rated evaporation capacity, the thermal efficiency of the boiler will be 10% 20% lower than the heat sales rate at the rated evaporation capacity. Only the coal-fired steam boiler has the highest thermal efficiency when the evaporation capacity is 80% to 100% of the rated evaporation capacity.

Therefore, coal-fired steam boilers are most economical in the range of 80% to 100% of the rated evaporation.

The boiler output --- refers to the output of heat DU power of the boiler in the BAI operating state, and the time unit is ZHI: hours.

dao/h.

The units of measurement are: MW h, kcl h, t h

The fixed evaporation capacity of the boiler is also called the boiler capacity, which refers to the maximum evaporation capacity of the steam boiler in long-term continuous operation when the rated steam parameters, the rated feed water temperature and the design fuel are used, and the unit is t h.

The amount of steam produced by a boiler per hour, which is used to express its ability to produce steam, is called evaporation (boiler output).

Rated evaporation capacity refers to the evaporation capacity (also known as boiler capacity) specified by the boiler when the rated steam parameters, the rated feed water temperature, the fuel selected at the time of use design and the efficiency are guaranteed.

Industrial boilers.

The products are divided into three major source categories: steam boiler and heat BAI

Water boiler, organic heat carrier furnace.

Steam boiler production.

The model number is composed of three parts, and each part is connected by a short horizontal line, namely:

1 - boiler form 2 - combustion mode 3 - rated evaporation capacity (t h) 4 - rated steam pressure 5 - superheated steam temperature (saturated steam not standard) 6 - fuel type.

Organic heat carrier furnace is divided into two categories: liquid phase furnace and gas phase furnace, and the product model of organic heat carrier furnace is composed of two parts, which are connected by a short horizontal line, namely:

1——— Furnace type code 2 - combustion equipment code 3 - furnace placement type code 4 - rated thermal power: kW 5 - fuel code.

Generally, hot water boilers are like this, for example: this is the model of hot water boiler, this is the model of steam boiler.

Hello dear, glad to answer for you: <>

The steam pressure of the steam boiler and the temperature of the boiler body is 171, according to the definition of steam boiler, there is a certain relationship between the temperature of the boiler itself and the steam pressure of the bright branch, and the correspondence can be found through the steam table. Assuming that the steam pressure of the steam boiler is, the saturation temperature corresponding to the steam pressure is 171 according to the steam sensitivity table. The boiler temperature of the steam boiler should be about 171.

Summary. Hello dear <>

The temperature of the superheated steam in megapascals is about 300 degrees Celsius.

What is the steam pressure of a steam boiler and what is the temperature of its boiler body?

Hello dear <>

The temperature of the superheated steam in megapascals is about 300 degrees Celsius.

The pressure of megapascals is 7 atmospheres, and the temperature of superheated steam rises by about 30 degrees Celsius for each additional atmosphere, and about 200 degrees Celsius for each additional atmosphere. The superheated gas temperature of the town is 100 degrees at 1 atmosphere, and the superheated steam temperature can reach about 300 degrees at 7 atmospheres. I wish you a happy life!

Hope mine is helpful to you ha.

The significance of the two boiler models is briefly described: (1) SG-1025; +(2)HG-3239 and compare the main source Li Shou to the difference between the two boilers.

Industrial boilers are divided into four main categories; Steam boilers, hot water boilers, steam-water dual-purpose type, organic heat carrier and multi-body heat conduction oil furnace. According to the different combustion mediums, steam boilers are divided into coal-fired steam boilers, oil-fired steam boilers, electrically heated steam boilers and others; Hot water boilers are divided into coal-fired hot water boilers, oil-fired hot water boilers, electroosmosis sensitive hot water boilers and others according to the combustion medium.

The steam parameters of a boiler are only the capacity, steam pressure, steam temperature and feed water temperature of the boiler.

The capacity of a boiler is usually expressed in terms of rated evaporation in t h. The neat pressure and temperature refer to the pressure and temperature at the main steam valve at the outlet of the superheater, the unit of pressure is MPA, and the unit of temperature is . The feed water temperature refers to the temperature entering the gas entry unit, or if there is no economizer, it refers to the temperature entering the boiler barrel.

In order to facilitate the design and manufacture of the manufacturing plant, the design department design and selection and the production department to use and maintain, and make the water pump, fan, coal mill and deaerator can be used together, it is necessary to uniformly stipulate the steam parameter series of the boiler nationwide.

Table 1-1 shows the parameter series of steam boilers in China.

As can be seen from the table, low-capacity boilers generally use low parameters, medium and small-capacity boilers use medium and high parameters, large-capacity boilers use ultra-high parameters and subcritical parameters, and boilers with a pressure of more than 14MPa have a reheat system.

The main parameters of coal steam boiler: rated evaporation, rated outlet steam, pressure, rated outlet steam temperature, feed water temperature, grate area, heating area, suitable coal type, coal burning capacity, water capacity.

China's steam boiler parameter series standard is "Industrial Steam Boiler Parameter Series".

Parameter standard for steam boilers: GB T1921-2004 "Industrial Steam Boiler Parameter Series".

The parameters of the steam boiler: the rated evaporation capacity of the boiler (t h), the rated steam pressure (gauge pressure) mpa, and the rated steam temperature
