In the edible oil manufacturing and processing industry, saturated steam is mainly used for heating, refining, disinfection and other processes. The edible oil industry has a high demand for steam and high hygiene requirements, therefore, edible oil factories also have high quality requirements for steam. Although the industry standard system in the Philippines is constantly improving, there still exists a problem of obvious product homogeneity and low technical content. This is mainly reflected in the low level of mechatronics integration, insufficient development capability of oil and fat deep processing equipment, dependence on imports for large-scale key technical equipment, and the need to improve equipment engineering and completeness. These factors have constrained the improvement of the technological level of the edible oil processing industry in the Philippines. Steam boilers provide essential steam and heat sources for the production of edible oil and they are crucial to the processing technology and production efficiency as one of the important production equipment. A large edible oil processing plant in the Philippines produces 30 tons of edible oil per day reaching this cooperation who focused on refining and deep processing of palm oil and coconut oil. The existing steam boiler of the factory has problems such as low thermal efficiency, unstable steam supply, and high fuel consumption, which seriously affect the continuity of the refining process and product quality with the expansion of market demand. The customer conducted multiple investigations and field visits, and ultimately selected the WNS4-1.25-Y (Q) series oil fired steam boiler produced by
Sitong boiler as the core thermal equipment for the production line to solve the problems they are facing.
This WNS4-1.25-Y (Q) series oil fired steam boiler customized by
Sitong boiler supports dual fuel switching. Due to the abundant supply and low cost of diesel and heavy oil resources in the Philippines, the edible oil factory select diesel and heavy oil as their boiler fuels. The customer can flexibly choose the fuels according to market fuel price fluctuations, thereby achieving the goal of reducing the operating costs. The refining of edible oil requires stable high-pressure steam, which is used for key processes such as degumming, deacidification, decolorization, and deodorization. The rated evaporation capacity of this boiler is 4t/h, which can accurately meet the continuous steam demand of the production line and avoid excessive product acid value caused by steam pressure fluctuations. The Philippine environmental protection department has strict requirements for industrial boiler emissions. While this WNS4-1.25-Y (Q) adopts a fully wet back structure and low nitrogen combustion technology with nitrogen oxide emissions below 80mg/Nm ³, which can meet local environmental standards. In addition, this oil fired steam boiler is equipped with an intelligent control system that can achieve functions such as one click start stop, automatic pressure adjustment, and fault alarm, reducing the difficulty of manual operation. At the same time,
Sitong boiler will also provide overseas technical support and spare parts supply to the customer for solving their worries about cross-border operations and maintenance. The picture shows the delivery site of the boiler:
