Sugar Industry Boiler

How to Choose the Suitable Boiler

Determine boiler capacity

Sugar production is characterized by high consumption of steam and low electricity consumption. The boiler is equipped with steam supply and turbo-generator to produce vapors for sugar-making process. In order to make rational use of heat energy and save energy, the method of co-generation of heat and power is generally adopted in the sugar refinery at present. The principle of determining electricity by steam is that the boiler steam output is subject to the process steam consumption while the power generation is determined by steam output.

Determine Boiler Pressure

In the past few years, the low-pressure boiler of 1.3mpa set up in Chinese sugar mills is unreasonable for the economic efficiency of steam and the utilization of heat energy in sugar mills. In recent years, the boilers of sub-medium pressure (2.5mpa) and Central Asia (4Mpa) are generally adopted in sugar mills, and remarkable energy-saving results have been achieved.

Steam Turbine Selection

The sugar factory is a seasonal production factory, which USES electricity and steam more smoothly during production, and the boiler also stops running during decompressing. The back-pressure steam turbine can meet the actual requirements of the sugar plant: high efficiency, combined heat and power generation, steam power. The inlet pressure of back-pressure turbine is usually 2.45mpa or 3.43mpa. High efficiency of heat energy, no need of condenser, simple equipment, relatively little investment, easy installation and maintenance.

Determine Boiler Efficiency

Boiler for sugar factory should be more efficient. The boiler output, the number of sets and other performance can adapt to the demand of heat load change, in order to facilitate economic management. If the use of one boiler operating at full load can meet the demand for steam, it is not appropriate to use two boilers operating under lower load. However, from the perspective of safety production, it is necessary to consider whether a single boiler in operation can be started quickly in a short time due to failure, so as to meet heating requirements without affecting production.

Capacity and Model

When boiler with different capacity and different types is selected, the boiler with the same capacity and combustion equipment should be selected. If not, try to construct the responsible line of equipment layout and maintenance management. The same model with different capacities or different models with same capacity could be choosed.
