A rated working pressure of the periodic inspection of hot boiler steam pressure in the boiler should be greater than the sum of the plate for the steam production required for the pipeline resistance and operating pressure. Do not neglect the steam pipe resistance, because the higher rated steam pressure, saturated steam temperatures will also increase. Second, the boiler heating surface heating surface (heat transfer area) is an important boiler (design) parameters. Because of the large output of Boilers generally large overload capability; otherwise, output is small. Same boiler capacity, a relatively large heating area, a lower exhaust gas temperature, the higher the efficiency of the boiler, fuel combustion heat is more fully utilized, consumes less. Third, boiler blowdown boiler blowdown is clean the inside, remove the sludge, reducing the effective measures of scale. Fourth, the construction furnace boiler furnace tube diameter is also one of the very important (design) parameters. After a lot of boiler running for some time in the furnace coke, smoke pipe soot accumulated soot, black smoke even began, will be a waste of fuel. The main reason is the diameter of the furnace small, atomized oil particles had a chance to be injected into the combustion furnace wall caused by high temperature carbonization. Thus, when selecting a gas boiler furnace to select a larger diameter.
The recent good news story: Union Square soon Group was named the provincial Federation of factory affairs leading group as "micro-small and medium private enterprises in Henan workers' congress building demonstration units" honorary title. Win the title, is inseparable from the efforts of all labor union workers, they work with their own solid foundation, effective operational mechanism and splendid achievements successfully nominated and award winning. Over the years, the Labor Union under the correct guidance of urban levels of trade unions, under the correct leadership of the Party, Comrade rely on the staff, smooth internal management channels, good to play the democratic management of conflicts "relief valve" business "stabilizer" and developing the "catalyst".
Why fuel gas-fired periodic inspection of hot boiler will turn off? Although the case of gas-fired boiler fuel oil dual boiler, but only that the furnace can be gas fuel, but a normal customer choice is to select a class of the final fuel only, even if a mixed gas, also belong to the category of gas.
2.4MW YQW series gas-fired horizontal thermal oil heater for food industryChongqing Sanyi Food Co., Ltd. is a modern food enterprise engaged in the production and sales of hot pot butter products and hotpot seasonings. Sanyi Food combines the second generation technology of advanced "physical high temperature deacidification" with the traditional process, in which the stable heat source provided by the periodic inspection of hot boiler meets the high temperature requirements of the production line.As the products sell well, Sanyi Food has built a modern comprehensive production base of more than 20,000 square meters in 2016, which adopted advanced automated production lines, and it was urgent to introduce energy-efficient boilers and use clean energy natural gas as fuel. ZOZEN became the boiler supplier of Sanyi Food due to its outstanding advantages in product performance and environmental protection effects. In order to meet the different requirements of the production line for temperature, ZOZEN customized the combination of YQW series thermal oil heater + WNS series gas-fired steam boiler system. Among them, YQW series thermal oil heater adopts forced circulation three-pass circular tube design for the sufficient heating surface. The energy-saving device added on the tail of the furnace body can greatly reduce heat loss, and the thermal efficiency is up to 95%. In addition, these two series of boilers are both equipped with advanced low NOx burner to realize the low emissions of NOx ≤ 30mg/Nm³; Moreover, the boilers are both adopt the packaged structure, after the boiler components are transported to the site, they can be put into operation once connecting to the electricity and gas, which greatly reduces the boiler installation cost.
The use of hot oil boilers with low pressure and safety systems requires fewer qualified employee than steam systems. Long-life use of the system: Hot oil systems can be used in enterprises without needing to be renewed for a long time if the necessary maintenance, periodic inspection and cleaning are done completely.Get a Quote

Inform boiler operators of your inspection and request that other boilers not be blown down during your inspection. Make sure all fuel, steam, blowdown, feedwater, and chemical feed valves are turned off and locked out. Never use a 110 V light bulb and lead in the boiler to avoid electric shock. Touch the bare metal before entry to ensure the boiler is not too hot for inspection.Get a Quote
