As of November 29, two 14 MW condensing vacuum boilers independently developed by Jidong Oilfield Machinery Co., Ltd. have been operating safely and steadily for 20 days. This is the single gas-fired vacuum boiler with the largest single power in China, each capable of meeting the heating needs of 200,000 square meters of residential area.
After testing, the average thermal efficiency of this type of condensing gas-fired vacuum boiler is up to 96%, which is 4 percentage points higher than that of conventional gas-fired boilers to 5 percentage points. It is expected that a single boiler can save more than 100,000 cubic meters of natural gas during a heating period.
In view of the low return water temperature of the heating system, the R&D team of Jidong Oilfield Machinery Co., Ltd. took the lead in applying the flue gas condensation technology to high-power boilers, and used the large amount of phase change latent heat released by partially condensing the water vapor in the flue gas for heating. Backwater greatly improves thermal efficiency. At the same time, the use of oxygen content feedback control of the distribution of wind technology, effective control of exhaust heat loss, reduce the generation and emission of harmful gases, energy saving and environmental protection effect is good.
This type of boiler is also safe, compact and easy to operate. The boiler shell pressure is always lower than the ambient atmospheric pressure, and the safety performance is excellent.
Investment casting is a kind of casting process. Some people call it "lost wax casting" or "precision casting". It can also be said to be a special casting improved from ordinary casting. Its precision and surface finish are higher than Ordinary casting is much higher. In some places where the precision requirements are not very high, investment castings can be used and assembled directly. Even in some positions that require precise assembly, we can meet the required requirements through local secondary CNC machining of the product, which can reduce the product's cost. Below are some of the investment castings we have done.
SCZY committed to the production of stainless steel, carbon steel, alloy steel and copper and other Metal Casting parts, and also provides professional follow-up secondary CNC machining (for places with high precision requirements and direct casting cannot meet the requirements) and various surface treatments etc. Our investment casting parts accuracy achieve CT4-6, surface finish Ra.1.6~3.2μm and the wall thickness can be reach 0.5mm. Our high-quality engineering team and quality inspection team ensure product excellent quality and in time delivery. We would be happy to provide a free quote for your upcoming project.
