The coal-fired boiler uses coal as fuel. The consumption of coal is a key factor to measure the efficiency of boilers. Under the same condition, the coal-fired boiler with less coal consumption can save more costs for enterprises. However, the coal consumption of coal-fired boilers is related to many factors, such as the efficiency of the boiler, the calorific value of fuel coal and the degree of coal combustion.
An Interlock in the boiler’s control system is a programmed or hardwired condition that forces a device to be in a pre-determined or permissive state before the process can continue.
Depending on design pressure, fuel type, either liquid, gas or solid, all steam boiler require interlocks to sequence the operation and to prevent damage to the boiler. Examples of such devices are High or Low Boiler Drum Water Level, Low Boiler Feed Pump Pressure, High or Low Fuel pressure, High or Low Atomization pressure (oil fired), Proof of Ignition, Proof of Flame, FD and/or ID (solid fuel) Fan Motor Operation or combustion air pressure, Damper or Valve position and High Boiler Steam Pressure as well as O2 and furnace temperature.
The principle of boiler heating is a kind of thermal equipment that uses the heat energy released after fuel combustion or the waste heat in industrial production to transfer to the water in the container, so that the water can reach the required temperature or steam with a certain pressure. After the water enters the gas boiler, the heated surface of the gas boiler transfers the absorbed heat to the water in the steam-water system, so that the water is heated into hot water with a certain tempe...
The 15-ton natural gas boiler refers to the heat energy conversion equipment that uses natural gas, liquefied gas, city gas and other gas fuels as fuel, burns the heat released in the boiler, heats the water in the boiler, and converts it into hot water or steam. It is worth noting that the heating of natural gas boiler is completed by a complete system. Here, ZOZEN Boiler will introduces the standard system configuration of 15-ton natural gas boiler.

Steam is one of the essential equipment in the production process of major enterprises, which is mainly used in drying, disinfection, sterilization, distillation and other technological links, and is widely used in many industries such as food, paper making, construction, cable, electronics, tobacco, textile and so on. Whether the boiler can operate efficiently and stably is directly related to the production efficiency of enterprises. The water supply mode of steam boiler is an important part t...
Coal-fired boilers use various types of coal as fuel. After the heat of coal is converted, steam is generated, which is often used in the production of heating, heating and thermal power generation. The model parameters of coal-fired boilers are different, and the cost is also different. Here, ZOZEN Boiler takes the cost of a 40-ton steam coal-fired boiler as an example for a brief introduction.

Gas boilers use clean energy as fuel, produce less pollution and have high thermal efficiency, and are widely used in all walks of life to help major enterprises achieve green development. However, there are many types of boilers on the market with complex performance parameters, and it is difficult to purchase a cost-effective gas boiler. Taking the price of 2 tons of natural gas steam boiler consulted by some users as an example, ZOZEN Boiler explains how to judge the cost performance.2-ton na...
Heating boiler is special equipment commonly used for heating in winter. When purchasing, users should first consider the heating efficiency and heating area of the equipment, which has a certain relationship with the model and capacity of the equipment. In this article, taking a heating steam boiler for 10000 square meters as an example, a reasonable selection is made for everyone.
