According to different combustion methods, industrial boilers can be divided into two types: stratified combustion and chamber combustion. Which combustion method does gas boiler and biomass boiler belong to? What is the difference between stratified boiler and chamber fired boiler? The pressure-bearing boiler can realize automatic water filling, how to realize it? 1. Stratum-fired boilers and room-fired boilers
1. Chamber fired boiler
Because the room-fired boiler has no grate device, it cannot burn lump coal. Generally, the fuel of the room-fired boiler is in the form of powder (solid fuel, such as pulverized coal), mist (liquid fuel, such as oil) or gaseous (gas fuel, such as Natural gas) is sprayed into the furnace (combustion chamber) along with air to perform suspension combustion in the boiler.
Adopting the stratified combustion method, the coal is conveyed on the plane of the chain grate through the coal feeder, and the combustion process is completed in the furnace. The gas boiler uses room combustion. After the natural gas is mixed with air in a preset ratio in the burner, it is sprayed into the furnace through a nozzle, and the torch is installed in the furnace to complete the combustion. Gas boilers are room-fired boilers.
2, layer-fired boiler
Generally, the boiler in which fuel is burned on the grate is called a stratified combustion boiler; stratified combustion means that after the boiler is ignited, the fuel is fixedly burned on the boiler grate, also known as the fixed-bed combustion method. The biomass boiler is a typical stratified boiler. Burning boiler.
2. How to automatically make up water for a pressure-bearing boiler
1. The pressure-bearing boiler uses an automatic make-up valve to make up water, and can realize continuous water supply of the boiler. The automatic make-up valve is similar to a pressure reducing valve. The size of the make-up pressure is controlled by adjusting the spring force. When the required make-up pressure is reached When the time, the automatic water replenishment valve automatically closes.
2. The automatic make-up valve is a new type of valve installed on the make-up pipeline of the closed-loop heating or cooling system. The make-up valve can automatically maintain the pressure of the system at the set value, and the check valve in the valve can prevent heating The hot water of the system is returned to the cold water pipeline. The internal filter of the water supply valve can prevent impurities from flowing into the system. Even if the pressure at the water supply end changes, the outlet pressure can be kept stable. The handwheel can completely cut off the water flow in emergency situations. The water supply valve is set to reduce pressure. A new high-tech valve with valve, stop valve, check valve, and filter functions in one.
The definitions of layer-fired boilers, chamber-fired boilers, and automatic water replenishment methods for pressure-bearing boilers are introduced in sequence above. If you have any questions, please refer to this article. Industrial boilers can serve a variety of industrial production. If you have boiler purchase requirements and plans, you must carefully select the type, select the appropriate boiler manufacturer, determine the reasonable boiler configuration, and ensure that the appropriate boiler is purchased to ensure the normal and stable operation of the boiler.
