Environment-friendly energy-saving boiler

Abstract

The invention provides an environment-friendly energy-saving boiler. The environment-friendly energy-saving boiler comprises a chassis, a boiler body is fixedly installed on the chassis, and the boiler body is internally provided with a boiler furnace and a reversal chamber which is located at the rear end of the boiler furnace; a combustion engine is arranged at the portion, corresponding to theboiler furnace, of the front end of the boiler body, the front end of the boiler body is further provided with a front smoke box, and the rear end of the boiler body is provided with a rear smoke box;and a first smoke tube group is arranged between the reversal chamber and the front smoke box, a second smoke tube group is arranged between the front smoke box and the rear smoke box, and a chimneybase which communicates with the rear smoke box is arranged on the rear smoke box. The environment-friendly energy-saving boiler is characterized in that an energy-saving condenser is installed on thechimney base and provided with a connecting smoke flue which is connected with a chimney; a smoke recirculating tube is arranged between the chimney base and the energy-saving condenser, the other end of the smoke recirculating tube is connected with an air inlet of the combustion engine, the volume of smoke, sucked into the combustion engine, in the smoke recirculating tube accounts for 10%-16%that of the smoke exhausted in the chimney base, and the volume heat load of the boiler furnace ranges from 850 KW / m<3> to 1,050 KW / m<3>. Not only can the using requirement be met, but also the environment-friendly energy-saving boiler is more energy-saving and environment-friendly compared with an existing hot-water boiler.

Description

technical field [0001] The invention belongs to the technical field of boilers, in particular to an environment-friendly and energy-saving boiler. Background technique [0002] Hot water boilers include electric hot water boilers, fuel-fired hot water boilers, gas-fired hot water boilers, and coal-fired hot water boilers. Hot water boilers are boilers that produce hot water. , solar energy, etc.) A thermal energy device that heats water to a rated temperature. Gas-fired hot water boilers include gas-fired heating boilers and gas-fired bathing boilers. With the realization of the national "West-to-East Gas Transmission" project, gas-fired boilers have gradually become people's first choice. [0003] The Chinese patent application with the publication number CN103697582A discloses a fuel-fired gas-fired atmospheric hot water boiler, which includes a boiler body arranged on a base, a water return port is provided at the bottom of the boiler body, and a water outlet and an air ...

AI Technical Summary

Problems solved by technology

Although the hot water boiler can meet the requirements of use to a certain extent, with the continuous development of my country's industry, the environmental load is increasing, so higher requirements for energy saving and environmental protection are put forward for the hot water boiler, and the hot water boiler Cannot meet the requirements of high efficiency and low emissions
