Ash accumulation on the heating surface.
The scaling and ash deposition on the water-cooled wall of the furnace and the ash deposition of the superheater, convention tube bundles, economizer and preheater can increase the thermal resistance of the flue gas, weaken the heat transfer, lessen the cooling effect of the flue gas and increase the exhaust gas temperature of the gas-fired boiler.
Too high excess air coefficient.
Under normal circumstances, as the furnace outlet excess...
Power boilers take the chemical energy stored in fuel, convert it to heat energy in the combustion process, and transfer that heat energy to water to produce steam. The transfer of energy from combustion gases to the water and steam is called heat transfer.
When it refers to how to reduce the procurement cost of industrial boilers, many corporate users will be first to take measures to effectively reduce the related costs involved in the boiler procurement process, such as the boiler equipment cost, transportation cost, loading and unloading cost, insurance cost, installation and commissioning cost, labor cost, acceptance and inspection cost.
In addition to quality, price is also an aspect that most corporate users are very concerned about when they purchase the gas-fired thermal oil heater, so what is the price of a set of high-quality gas-fired thermal oil heater?
1. The types and parameters of thermal oil heater, such as rated thermal power, rated working temperature, etc.
Rated thermal power: heat output per unit time. Thermal oil heaters with different heat output per unit time have different prices.
Rated wor...
Biogas is the mixture of gases produced by the breakdown of organic matter in the absence of oxygen (anaerobically), primarily consisting of methane and carbon dioxide. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. Biogas is a renewable energy source.
Biogas is a byproduct of the decomposition of organic matter by anaerobic bacteria. Biogas is typically composed of 60% methane and 40% CO2...
According to the Wikipedia, Second-generation biofuels, also known as advanced biofuels, are fuels that can be manufactured from various types of non-food biomass. Biomass here means plant materials and animal waste used especially as a source of fuel.
Advanced biofuels are renewable fuels derived from renewable biomass that achieve a fifty percent greenhouse gas emissions reduction over conventional biofuels. The definition of advanced biofuels includes cellulosic biofuels, biomass-bas...
A condensing boiler can condense the water vapour in the flue gases and withstand the corrosive and acidic qualities of the flue gas condensate. Although most boilers can condense the flue gasses, only boilers that have heat exchangers constructed from materials able to withstand the corrosion should be used in condensing application. Condensing boilers with primary and secondary heat exchanger do not work well as they are not able to fully condense and defeat the purpose of using a condensing boiler. Also, boilers with this arrangement are prone to condensation in the primary heat exchanger at lower firing rate which can cause damage to the heat exchanger.
One of the biggest issues related to natural gas explosions is that in the industrial world, people just don’t understand that natural gas piping repairs are different from other piping repairs.
