gas fire steam boiler prices

Gaz than fire steam boiler prices should be how to calculate? Q: ratio of gas steam boiler gaz simple algorithm is multiplied by the calorific value of coal and boiler efficiency is calculated by dividing this simple assumption does not heat to the steam boiler efficiency of 80%, coal calorific value 5500, if the amount of steam produced a ton of coal can be calculated as follows * 0.8 = 5500/600 = 7.3, ie: gaz ratio of 7.3 can be calculated simply, is this right? A: According to your argument: the amount of steam a ton of coal produced, commonly referred to as the evaporation rate of the fuel, commonly known as steam coal ratio. The calculation formula is: base received low calorific value of coal is then divided by multiplying the thermal efficiency of the boiler (steam heat feedwater minus heat). You said above is correct.

Technical characteristics: the overall cost of natural gas boiler is half the coal-fired boilers, and operation costs are four times as coal, a ton of steam needs to burn about 80 cubic meters of natural gas, and coal-fired no more than 0.185 kg, the economic accounts will be considered . Select the gas boiler it under certain conditions choice of last resort. As well as on the performance of the gas is better than coal. In principle, they are heat transfer equipment, the difference is that on combustion, complex grate or coal, coal preparation, etc. as well as coal needs, while gas only burner that simple. Use of cleaning gas boiler: boiler after a long run, the inevitable emergence of scale, mainly due to the scale of the problem of corrosion, formation of boiler feed water with hardness components, through subsequent high temperature and pressure continuously concentrated by evaporation in a furnace a series of physical and chemical reactions that ultimately form a hard heating surface, a dense scale, resulting in reduced heat transfer and the effect of corrosion under the scale factors, will result in reduced boiler waterwall furnace heat absorption, furnace outlet temperature of the boiler is increased, so that increased boiler losses. After scaling while reducing the heat transfer within the water wall, water wall tube wall temperature may lead to increased water wall lead to burst pipes, affect the safe operation of the boiler. The first of scale is detrimental boiler, the boiler is the main cause of accidents, the danger main problems: wasting a lot of fuel: Because only one of very few steel thermal conductivity of scale, so when the heating surface fouling will heat blocked, in order to maintain a certain boiler output, it is necessary to increase the temperature of the side of the fire, so that the external radiation and flue gas heat loss. Now it can be used efficient and environmentally non-corrosive cleaning agent gas boiler cleaning, cleaning Fu World Tektronix cleaning agent scale was completely dissolved, the equipment expose the metal tube primary colors, because the reduction of algae and biological sludge fouling effect. At the same time stripping the role of iron oxide and iron oxide Asia, extended gas boiler service life, reduce energy consumption and improve productivity.

Boiler steam temperature affect the safety and economy temperatures above will be lower than the rated temperature of the device, it 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. Ruoyin with water vapor causes a decrease in temperature, the moisture in the salt impurities formed in the superheater scale, pipe valves, gas turbine blade, because the superheater lead to reduced heat transfer, the temperature decreased, damage increased wall temperature; and cause the valve plug, the operation failure; and a gas turbine blade erosion, loss of balance and vibration occurs. Temperature fluctuations reason superheater actual heat transfer the vapor does not reach the required amount of heat absorbed corresponding balancing. When the heat absorbed is greater than the heat transfer, the temperature rise; conversely decreased. Many factors affect the temperature change, including both gas side and the vapor side. Such as boiler load increased, but also to ensure the boiler load unchanged or decreased in order to prevent pressure shall increase the amount of fuel and air supply, strengthen the burning, causing the furnace exit flue gas temperature of the flue gas volume increases and lower water temperature , temperature increase; If the oil and gas fuel is combusted in the furnace carbon black is not fully formed, into the superheater flue causing secondary combustion, but also greatly increase the superheat temperature. Reducing the temperature of the main reasons: improper adjustment of combustion, low flame center furnace; superheater area is small, or too much leakage at the furnace wall; Save water flow rising or temperature reduction; drum water level or high gas-water separator separating efficiency is lowered, the humidity of the vapor is increased; superheater tube fouling, reduced heat absorption and the like.
