Biomass boilers do produce emissions when they burn organic materials such as wood chips, pellets, or agricultural waste. The exact type and amount of emissions depend on various factors such as the type of fuel used, combustion efficiency, and air pollution control technologies in place. However, with proper design and operation, biomass boilers can emit significantly less pollutants than traditional fossil fuel boilers, making them a more environmentally friendly option for heat and power...
High exhaust temperature in a biomass-fired boiler can be caused by several factors, including:
1. Insufficient air supply: If there is not enough air supplied to the combustion chamber, the fuel may not burn completely, resulting in high exhaust temperatures.
2. Excessive fuel supply: Excessive fuel supply can overload the boiler, causing incomplete combustion and high exhaust temperatures.
3. Improper combustion: Improper combustion can lead to incomplete fuel burning and high exhaust tempe...
Boiler economizers are devices that help to improve the efficiency of industrial boilers by recovering heat from the flue gas and transferring it to the boiler feedwater. In this article, we will explore how boiler economizers work and the benefits they offer. We will also introduce ZOZEN's boiler and economizer solutions that can help improve the energy efficiency of your industrial operations.
How Do Boiler Economizers Work?
A boiler economizer is essentially a heat exchanger that recovers w...
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.
Most petroleum products can be used as fuel, and boiler oil is a kind of refined oil, which is widely used in power plants and industrial boilers. Boiler oil is mainly made of petroleum cracking residue oil and straight-run residue oil, which is characterized by high viscosity and high content of non-hydrocarbon compounds, gum and asphaltene.
The formula of boiler oil mainly includes the following indicators: viscosity of the boiler oil, sulphur content, density, flash point, water content and ...
The economizer of condensing gas-fired boiler can be installed in the flue of the current CFB boiler, to recovery the energy from the high-temperature flue gas, in order to reduce the fuel consumption. Also, the economizer helps to absorb the air pollutants such as the NOx and sulfur dioxide.
Ensure that the vent valve on the boiler is open and check there is no pressure in the boiler. Check that the steam stop valve is closed. Check that all the valves for fuel are open, and let the fuel circulate through the system until it comes to the temperature required by the manufacturer recommendation.
