The high heat transfer of the boiler requires good medium. With the improvement of boiler in the production technology and intelligenlization, gas-fired boilers have more strict requirements for boiler operation medium in order to improve the boiler operating performance, reduce boiler failures and costs.
Biomass-fired boilers can burn many fuel types, but they all belong to biomass energy, such as corn stalks, wheat straws, straws, peanut shells, corn cobs, cotton stalks, soybean stalks, weeds, branches, leaves, sawdust, bark and other solid waste of wood or furniture factories.
Due to the development of boiler technology and relevant policies, gas-fired boilers using eco-friendly fuels are often applied for heating. For thermal power companies, cost is the most important issue.
The thermal oil heater, also called the organic heat carrier boiler, is a kind of once-through boiler developed based on the forced circulation design concept. With gas, oil or coal as the fuel and heat conducting oil as the medium, the thermal oil heater adopts the thermal oil pump to force the medium conducting the circulation in the liquid phase. The medium transfers the heat energy to the heating equipment and then returns to the furnace for being reheated. The thermal oil heater has the advantages of high-temperature and low-pressure heating and precise control of the medium.
The dual-fuel boilers usually burn oil and gas fuel which can be natural gas fuel or artificial gas fuel such as natural gas or diesel. The field-assembled dual-fuel boilers also burn the heavy oil or light oil. This type of boiler can make enterprises select the fuel more flexibly and minimize the boiler operating and production costs for enterprises.
The coal-fired boiler has low fuel costs and high calorific value, which is a kind of important auxiliary heating equipment in the production-oriented enterprises. However, the coking on the furnace wall is common in the operation of the coal-fired boiler.
The gas-fired boiler has outstanding eco-friendly advantages, which makes it stand out among various boilers. Due to the high efficiency and fuel characteristics, the gas-fired boiler has many protective measures in the operation.
