gas superheated steam boiler

6 tph WNS series condensing gas-fired superheated steam boiler for food industryFounded in 1991, Sichuan Liji Pickles & Flavouring Co., Ltd. is a large-scale agricultural and sideline products processing enterprise mainly engaged in the production of pickles, seasonings and red oil series dishes. In order to greatly improve production efficiency and effectively guarantee the stability of product quality, Liji Pickles & Flavouring introduced a series of automated production lines. The boiler is one of the important equipment in its automated production line. The sterilization and disinfection processes during the processing require the steam provided by the boiler.After inspecting many boiler manufacturers, ZOZEN's high-quality equipment and refined services won the trust of Liji Pickles & Flavouring and the company decided to purchase one set of 6 tph WNS series gas-fired steam boiler. This series of gas-fired boilers adopts a full corrugated furnace to enhance the smoke disturbance and effectively improve the heat transfer effect. The threaded tube is a high-efficiency heat transfer element developed by ZOZEN for many years, which can effectively absorb the flame energy after continuous optimization. With the finned tube condenser added at the tail of the flue, the boiler thermal efficiency can be as high as 98% as well as reducing the exhaust gas temperature. In addition, The fully automatic intelligent control and safety detection device ensures the safe operation of the boiler and provides a stable and reliable heat source guarantee for the efficient operation of the Liji Pickles & Flavouring automatic production line.

Method for safe operation of superheated steam boilers steam boiler before use, must be checked for damage of the insulating layer, to check the burner is operating correctly, and to check the position of the opening degree of the valve to ensure it is correct. Must be checked for automatic control instruments and equipment safety equipment accessories, equipment, in order to comply with the requirements. Check item prior to ignition of the steam boiler: open valve before oil circulation pump, oil heating valve is opened, adjusted reasonably high level of the tank, the gas pressure is determined before the natural gas burner ignition must be within the range, the power good . Refers to the operation of the steam boiler is refluxed pressure activated device circulating pump, the circulating pump outlet, inlet, outlet, and the system, it is in the normal range. Circulation pump run for 30 minutes. After the stability of the system, the next step. Open the gas tube steam boiler manual valve, button start-up burner, natural gas burner into the furnace, and then the ignition, the flame remains stable, i.e. is in a safe operating condition. In the firing process steam boiler, if you accidentally quenching phenomenon occurs, the device will automatically interlock burner saver appear. It must be promptly cut off the natural gas pipeline to start the furnace purification. Replacement of the residual gas in the furnace and closed. The system load requirements, temperature requirements and thermal oil outlet, the burner can automatically adjust the size of the fire source.

Before a cooperation with the parties, we heard from other companies where fast boiler brand, saying it was so fast square product quality, use a long time, and after-sales service is also very complete. After the collaboration found that it really is a well-deserved reputation. This three boilers put into use, not only reduces emissions, while meeting the needs of normal heating, fuel input has also been reduced, as we save a lot of operating costs. --customer feedback

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.
