47 bar coal fired boiler
Because of the characteristics of domestic resource structure coal once had a large proportion in the resource structure so the coal-fired 47 bar coal fired boiler was also in a prominent position in the market. However, with the change of resource structure and environmental pollution in recent years, gas-fired boilers are gradually replacing coal-fired boilers and becoming the main force of the new market because of their natural advantages. Gas-fired boiler market is gradually obvious, has its own obvious advantages, the following comparative analysis of the advantages of gas-fired boilers. Gas-fired boilers are fueled by natural gas, which burns rapidly and produces great power, so it is also efficient, and its efficiency is 50% higher than that of coal-fired boilers. . Although natural gas prices are higher than coal prices, apart from the cost of fuel, as long as the pipeline can be invested. Coal-fired boilers, in addition to fuel costs, transportation costs, labor costs, storage costs, etc., the overall price is not cheap. Therefore, from the cost-effective point of view, natural gas as a whole has more advantages. Natural gas is one of the most environmentally friendly sources of energy by far because of its abundant combustion, clean combustion and pollution-free emissions. Coal combustion emissions sulfur, ash content is more serious pollution to the environment, which is also incomparable with gas-fired boiler. Gas-fired boilers can bring greater environmental benefits to enterprises.
In textile industry, steam 47 bar coal fired boiler is an essential device and it can supply steam to drying, power generation, etc. However, textile industry is suffering from energy crisis specially gas, low pressure and high demand among residence in winter causes complete breakdown. So, it’s high requirement to shift on alternate energy resources e.g. Coal. Country is very rich with its coal reserves and it can serve for quite long. In this post we will discuss possible energy alternates for textile industry, Economical aspect (Costing), Merits and demerits involved. Major focus is on costing to evaluate efficiency of different energy resources.Industry utilizes different kind of boilers with varying pressure and of different capacities as per unit requirement.
Provide for the growers Kingenta Ecological Engineering Group, the main compound fertilizer, slow release fertilizer, water soluble fertilizer, bio-fertilizer, soil conditioner, etc. required for a full line of soil and - with another giant fertilizer industry enterprises farming solutions services. 2016, Kim Jong large group with my company, to buy one of two 10 tons of steam condensing steam 47 bar coal fired boiler (WNS10-1.25-Y.Q). It is the product side were quick constant pursuit of quality, in-depth research and development of control and intelligent control, boiler energy efficiency as well as high demand for continuous improvement of energy efficiency and emissions, making the fertilizer industry's two leading companies invariably choose the fast way hand in hand!
According to this feature, the blower must be segmented to meet the needs of the combustion. Although the current domestic production of 47 bar coal fired boilers are taken into account this feature, using the sub-air room, and is equipped with a damper. However, according to the survey, many units in the actual operation is not performed in accordance with the combustion characteristics of air volume control, the amount of air required for combustion and an actual amount of supply air does not fit very well, so that incomplete combustion loss increases. Therefore, adjustment the combustion in the boiler, the air amount to be supplied to the combustion timely adjusted according to need, to reduce heat loss and improve the thermal efficiency. 3. The use of secondary air. Strengthening of the combustion secondary air stream is very effective, it has the following effects: (1) strengthening the furnace turbulence and mixing of the gas stream in the furnace oxygen and fuel gas are uniformly mixed, so that the chemical loss of incomplete combustion and furnace excess air coefficient is decreased. (2) the secondary air vortex formed in the furnace flue gas, on the one hand to extend the suspension of fine coal particles travel in the furnace increases the residence time of the suspension of fine particles in the furnace, so that there is sufficient time than combustion, incomplete combustion to reduce heat loss; on the other hand due to the separation effect of the vortex gas flow, the coal particles and ash particles thrown back to the furnace, reducing the amount of fly ash escaping the mechanical incomplete combustion to reduce heat loss. (3) the high temperature secondary air in the furnace flue gas is improved fullness, that eliminates dead reduced stagnation zone and improve the utilization of the furnace heating surface. In addition to the secondary air had a marked effect on energy conservation, but on the smoke and dust is also very effective.
