large stainless steel water boiler

Expected by the end of October this year, Baoji City, Shaanxi Province will be completed 35 tons of steam, Chaigai actions totaling 379 coal-fired boilers, to achieve 35 tons of steam coal-fired boilers "clear" mandate.

Since 2013, environmental departments at all levels Baoji joint cooperation, overcome difficulties, temper forward, the coal-fired boilers Chaigai range extends from the urban area to the entire administrative region, Chaigai scale from 10 tons of steam and extended to the following 35 tons of steam, so far a total of Chaigai coal-fired boiler to reach 5424 units 8060.8 tons of steam, strong contributing atmospheric pollutant emissions and urban air quality continues to improve.

This year is the 35 tons of steam coal-fired boilers "cleared" ending of the task, do the task Chaigai 35 379 tons of steam coal-fired boilers is still very difficult, which, as a county district government initiative to advance planning, increase investment in clean heating, diversified ways to implement the transformation of coal-fired boilers. Currently, there are 59 sets of undesirable coal-fired boilers were removed.

Baoji City, iron-fisted rule haze headquarters director, he said: "We, as the lead department, attaches great importance to coal-fired boilers Chaigai work, held a special meeting to study the deployment of Chaigai work, in accordance with the door-to-one by one to find out the basis on Chaigai way, go through the county publicity, on-site guidance to support, on-site supervision and verification, etc., to urge coal-fired boilers Chaigai work for the city within the new investigation and the coal-fired boiler is within the range of Chaigai, one will find a Chaigai to ensure that before the end of the city's 10 coal-fired boilers Chaigai work perfect ending. currently, the city Qishan County, New District, Jintai District Chaigai has been basically completed the task. "

High temperature or below the rated temperature of the device, will have a bad effect. If the temperature exceeds its rated value, the boiler will cause overheating of the relevant metal material, material creep acceleration, will shorten the life of the boiler. If the temperature is too high, but some of the key components of the boiler would cause damage, can also cause serious and even superheater tube rupture. If the temperature is lower than the rated temperature, vapor enthalpy is reduced, increased air consumption, decreased economy. This will reduce the thermodynamic cycle efficiency of the plant, the steam humidity at the last stage blades of the gas turbine increases, causing erosion and damage to water droplets gas turbine blades, affect the safe operation of the gas turbine.

How to adjust and control excess air in boiler furnace?

Excessive air in the boiler furnace will affect the furnace combustion. Therefore, how to effectively control the air excess coefficient is one of the prerequisites for ensuring the reasonable operation of the boiler. Today, we will explain the excess air in the gas boiler with high degree of automation as an example: Furnace air excess coefficient is one of the important indicators to control the combustion process of gas boiler furnace. For the layer furnace, the air excess coefficient at the exit of the furnace is generally between 1.3 and 1.5. According to the air leakage of each flue section of the flue gas, the air excess coefficient of the exhaust should be 1.8-2.0. There are three factors that determine the heat loss of smoke exhaust: exhaust gas temperature, air excess coefficient and cold air temperature. Among them, the air excess coefficient of gas boilers is the main influencing factor. Excessive air excess factor is a great waste. A large amount of cold air enters the furnace, firstly reducing the furnace temperature, the combustion conditions tend to be unstable, and the volume of the flue gas is increased, and the heat loss of the exhaust gas is increased. Calculations show that when the air excess factor is increased from 2.0 to 3.0, the exhaust heat loss increases to 4.5%. At the same time, the burden of the blasting fan is increased, and the power consumption is increased. In order to improve the thermal efficiency of gas boilers, it is necessary to pay attention to and improve the understanding of the serious hazard caused by excessive air excess coefficient, and strictly control the air excess coefficient in combustion regulation, which is a field often overlooked in the heating industry.

Gas boiler room construction principle: At present, gas steam boiler, gas hot large stainless steel water boiler is widely used in all walks of life, in order to ensure the safe operation of the gas boiler, the user must consider the full range at the time of the construction of the boiler room.
