gas fired 4 ton steam boiler

Phase out coal-fired boilers, promote air pollution control is an important measure to improve the air quality of the environment. Zhangjiakou City, Hebei Province, according to the central and provincial government deployment requirements, in-depth launched out of control for coal-fired boilers, and comprehensively promote the city's 35 tons of steam / coal-fired boiler sales and less "clear" work to ensure the city's air quality improved and enhanced.

The phase-out of coal-fired boiler from the following three points.

First, the coal-fired boilers carry out a comprehensive investigation work.

Depth investigation and the remodeling phase out coal-fired boilers and "coal to electricity", "coal to gas" and so on, electricity consumption by verifying the number of boilers and eliminated the need for the transformation of gas to develop a control list in 2018 coal-fired boilers to natural gas, electricity security for the ability to determine the "coal to electricity", the number of "coal to gas," the boiler. Do a boiler in a table, as well as finishing the complete elimination of the transformation of the way, rectification, acceptance, responsibility for people's list, to lay the foundation for the next phase out coal-fired boilers governance.

Second, carry out the phase-out coal-fired boilers.

Carry out a comprehensive phase-out 35 tons of steam / hour and below the coal-fired boiler, stove, operating a small coal stove, the main urban built-up areas and the urban fringe, and built-up areas within the county Economic Development Zone range, a ban on new coal-fired boilers other regional ban on new 35 steam tons / hour and below the coal-fired boilers. For central heating central heating in the official website of the area covered, when not incorporated central heating, heating mode using a variety of propulsion power, natural gas, industrial waste heat utilization, and energy from the source to control pollution.

Third, strongly promote the boiler-depth treatment.

Focus on pollution control bulk coal, comprehensive transformation of the use of coal boilers and generators. Stoker addition, stoker furnace, over the remaining 65 tons of steam / h coal-fired boiler to complete the transformation process ultra-low emissions, the city above 35 t steam / hour is then mounted boiler line monitoring devices, and environmental protection authorities and networking, production facilities and quality facilities simultaneously, real-time monitoring.

Fire boiler design pitch is much: a room, boiler production plant belongs to class D, to a fired 4 ton steam boiler rated evaporation 4t / h, when the rated output is greater than 2.8MW hot water boiler, the boiler room building fire resistance rating of not less than two ; rated evaporation steam boiler is less than or equal to 4t / h, when the hot water boiler is equal to or less than the rated output 2.8MW, between the boiler building fire resistance rating of not less than three; m-inter-tank, oil pump and the oil heater are inter production plant belonging to class C, not less than two of its construction fire rating, between said room is arranged within the auxiliary boiler room, a room should be set apart from other firewall; March and gas regulator production plant belonging to Group A, which building fire rating of not less than two, should be provided between the boiler room and the immediate neighborhood regulator firewall spaced boiler room, which doors should open outwards and should not directly access to the boiler room, the ground should not be spark Ping.

How much gas fired 4 ton steam boiler power and water consumption about? One ton of steam coal boiler is about 85 kilograms, a ton of steam consumption of natural gas is about 80 square. I do not know the local fuel prices. Meanwhile, steam boiler tons of gas consumption to about 7 degrees, and tons of gas boiler steam power was insufficient. This is the cost of consumption, you can according to the local point, calculate the cost of coal. Other aspects of superior gas or gas, such as environmental protection, operating environment, repair and maintenance.

Preparation and method for measuring the moisture content of the flue gas of the boiler before the boiler purchase this product knowledge and understanding, the present, it is necessary for two reasons, first, it is the site of important product and the main key one word, and second, the products are widely used, why we have these conclusions and specific requirements. Meanwhile, I hope that we can be taken seriously and, in order to have learned well and apply their knowledge to practical work flexibly. Is there some preparatory work before the boiler 1. buy? Boiler products to buy, this is an important job, and need to be taken seriously, but also want to take into account all relevant factors, in order to have accurate judgments and the correct choice, a good choice to avoid mistakes. Before carrying out this work, is the need to do some preparation, use of the product to the environment and have a clear understanding of the requirements and learn about product origin, specifications, technical parameters, materials, quality, price, service and product manufacturers these and other basic information, in order to compare and consider, then, the right to choose their own products. 2. whether Sheung Shui before the boiler starts have specific requirements? From a professional point of view, Sheung Shui before the boiler starts, there are some basic requirements, which specifically is: If the hot water boiler, the water speed before it starts not too fast, not be less than the winter time Sheung Shui 4 hours, in other seasons upper water time of not less than 2-3 hours. And, at the beginning of the water, its water speed to slow. If the boiler is cold, it's inlet temperature in the range of 50 ℃ -90 ℃, and the difference between the water temperature and the temperature of the drum wall into the steam drum, not greater than 40 ℃. 3. What is the chain boiler? Chain boiler, which is a particular kind of a boiler, a higher degree of mechanization layers fired boilers, the time the track grate with a chain similar to these so called chain boiler A boiler. Further, it is a pre-boiler, the coal combustion process is completed in the movement. Advantage of this kind of boiler, the combustion condition is stable, high thermal efficiency and easy operation, in addition, its low concentration of dust emissions. However, it should be noted that the moisture content of the larger, more ash and strong coking coal, not suitable for this kind of boiler for combustion. 4. How the moisture content in the flue gas boiler measured? Determination of moisture content in the boiler flue gas, which is the weight measurement method, condensation method, and three psychrometer, and the moisture content of the flue gas is typically in the volume percent of water vapor in the flue gas content to represent. If dark gravimetry, need to use hygroscopic agent, the hygroscopic agent used is calcium chloride, calcium oxide, silica gel, alumina, phosphorus pentoxide, magnesium perchlorate and the like.
