bathroom natural gas steam water boiler dealer

Cade Shopping Mall is located in central Shanghai Hongkou District, Shanghai Daily larger flow of people in the region. The introduction of Shanghai air pollutant emission standards, boiler flue gas emissions of nitrogen oxide emissions to less than 80 mg / m, Shopping Mall a coal-fired boilers have been used for many years, NOx emissions far super to this request, the urgent need to replace more environmentally friendly low nitrogen emission boilers. Other units through the use of fast Boiler introduction and understanding, determined and fast boiler to achieve cooperation, party fast to their specific needs to recommend one condensing gas hot bathroom steam water boiler dealer of a 4.2MW for heating needs of the shopping center.

4tph WNS gas-fired firetube boiler project for food industryBoilers are mainly used to provide steam for drying, refining, destaining and other processes in the productive progress of edible oil. As a children company of AnHui COFCO Biochemical, AnHui COFCO Edible Oil Co.,Ltd. is founded on 2000, producing premium quality edible oil from corn germ, rapeseed, peanut, soy bean etc.. In order to develop the circular economy, COFCO has taken an active part in energy saving and emission reduction these years. The company adopts reliable and advanced waste water treatment system, meanwhile, the environment protection facilities also produces ammonia sulfate, feed and methane as by products. Therefore, they’d like to use desulfuration methane as the fuel for boiler to improve economic returns. They have planned to order one set of methane-fired boiler. ZOZEN’s WNS series firetube boilers have drew their attention by remarkable performance. This kind of firetube boilers is adaptable for various fuels, including natural gas, methane and coke oven gas. Large corrugated furnace is adopted for complete combustion. Meanwhile, engineers of ZOZEN also add the condenser, economizer and other energy-saving equipment at the end of flue gas duct in accordance with actual demand of the company, which makes the thermal efficiency reach above 98%. Furthermore, it equips with advanced combustion apparatus for lower NOx emission.

How much gas 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. At the same time, coal-fired steam power boiler tonnes to around 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 superior to coal or gas, such as environmental protection, operating environment, repair and maintenance.

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.
