Application
Steam boiler is an important equipment for chemical production, and the steam produced by it is an indispensable source of heat and power in chemical enterprises. Steam boiler is suitable for all kinds of chemical industries, such as fertilizer plant, oil refinery, feed plant, coating plant, plastic plant, glass plant, sulfuric acid plant, coal chemical, petrochemical and so on.
According to the utility of boiler, it could be steam boiler or hot water boiler.
Boilers are divided into fuel oil gas boilers, coal-fired boilers, biomass boilers, electric boilers. Gas boiler is convenient to control the temperature. However, it is necessary to consider whether it is convenient to install the gas pipeline. If it is not convenient, it is necessary to consider the use of oil-fired or electric boilers. However, oil-fired boilers need to consider transportation and storage issues, and electric boilers need to install special electrical equipment.
he capacity of the boiler shall be calculated according to the heat load curve or the heat balance system diagram, and the heat loss into the pipeline, the heat used in the boiler room and the available waste heat.
Boiler should have high efficiency. 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.
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.
