2200 kw gas fired boiler

2200 kw gas fired boiler

Coal-fired 2200 kw fired boilers to gas boilers benefits and precautions With the rapid development of national energy-saving environmental protection, the traditional coal-fired boiler can not meet the needs of the times. Therefore, the coal-fired boiler biomass boiler or gas boiler has become in many boiler user's choice. Before the transformation, to understand the difference between .1 and gas boiler fired boiler. Circulating fluidized bed combustion boiler fired by coal crushing device fluidized combustion process, the coal by crushing device percutaneously into the bunker through a the spreading coal coal injecting air into the furnace; circulating ash by heating, fluidized combustion process. When the coal into a gas fuel is injected directly into the combustor for combustion. 2. Combustion of Coal is mainly composed of C, H, O, N, S, ash and moisture and other elements. Generated when coal SO2, SO3, NOx ash and moisture, and SO2, SO3, NOx from flue gas emitted into the atmosphere, pollute the environment and cause harm to humans. The main components of the exhaust gas and coke are CO and H2. The main produce CO2 and H2 post-combustion, much lower than coal-fired boiler SO2, SO3 and NOX emissions. 3. Ventilation pressurized combustion coal combustion boiler used in a combustion mode. The bottom of the combustion process through the induced draft fan with fan and completed. In the combustion of coal, it requires a lot of air. Gas under a slight positive pressure in the boiler or burner slightly negative pressure, which requires less airflow. Burner air may be pre-mixed with natural gas. 4. coal boiler control reasons, material thickness, amount of wind, the wind volume, wind and other than coal, coal-fired boiler is difficult to automatically adjust the operating parameters of the boiler according to the load. However, fewer factors gas boiler, the burner valve can be adjusted according to the size of the load, easy to implement automatic control. Coal-fired boiler to a gas boiler Notes: Main results are as follows: (1) small boiler, the coal-fired boiler to a gas boiler, i.e. the negative pressure of combustion from the original to the current combustion slight positive pressure, and must pay attention to the furnace wall structure sealing problems. Closely related (2) selection and arrangement of the burner and furnace, the degree of filling of the flame in the furnace is preferably not formed dead air, to avoid the interference of adjacent flame burners, to avoid interference from adjacent burner flame. Unburned gas - air mixture should not be in contact with a heated surface, in order to avoid incomplete combustion. Gas combustion. Gas burner arrangement disposed conduit and ducts should be considered reasonable gas pipe and duct arrangement, ease of operation, inspection and maintenance. (3) the transformation of coal-fired boilers is mechanized layered gas boiler should be removed before the arch and the arch, and the bottom heating surface increases, in place of the grate, the grate to prevent overheating. Gas Velocity (4) on heat transfer surface of the fly ash is not restricted abrasion conditions, convection heating surface heat transfer coefficient is increased, increasing the pressure in the boiler where H is unduly increased. Boiler erosion surface. At this time, the capacity of the boiler should be noted that the steam separator to ensure the quality of the steam.

Natural gas as a clean energy, can be reduced nearly 100% of the sulfur dioxide and dust emissions, 60% of carbon dioxide emissions and 50% of nitrogen oxide emissions, and help to reduce acid rain, global warming alleviate, reduce proportion of the amount of coal energy important energy; corresponding gas 2200 kw fired boiler has gradually been used and popular.

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 2200 kw 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. "

How many two tons mill electric steam 2200 kw fired boiler price for the textile mills, there are also many places due to abundant natural gas resources department, need to use electric heating steam boiler, so that, for businesses, in the choice of electric steam boilers when . It must be to look at the country of boiler manufacturers for comparison, in particular, to pay attention to the brand of the steam boiler manufacturers and after-sales service. In this case, for enterprises, pre and post sales are guaranteed. Recently, a textile enterprises to fast boiler consulting, want to buy an electric steam boiler, but for the specific needs of the model and the price is not very understanding. This is the fast boiler technician needs the help of accounting price after accounting concluded that two of the mill with a 2-ton electric steam boiler is possible. Currently, the model price of about 200,000. Therefore, the company for the price of two tons electric boiler steam mills already have a detailed understanding.
